By contrast, +our General Public Licenses are intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + Developers that use our General Public Licenses protect your rights +with two steps: (1) assert copyright on the software, and (2) offer +you this License which gives you legal permission to copy, distribute +and/or modify the software. + + A secondary benefit of defending all users' freedom is that +improvements made in alternate versions of the program, if they +receive widespread use, become available for other developers to +incorporate. Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/ultralytics/MANIFEST.in b/ultralytics/MANIFEST.in new file mode 100644 index 0000000000000000000000000000000000000000..cd7df3ee93004aab1f57213c65f9b4b06f35fce5 --- /dev/null +++ b/ultralytics/MANIFEST.in @@ -0,0 +1,8 @@ +include *.md +include requirements.txt +include LICENSE +include setup.py +include ultralytics/assets/bus.jpg +include ultralytics/assets/zidane.jpg +include tests/*.py +recursive-include ultralytics *.yaml diff --git a/ultralytics/README.md b/ultralytics/README.md new file mode 100644 index 0000000000000000000000000000000000000000..660c35034c2f4291890c50f82908ec931fb9e9b8 --- /dev/null +++ b/ultralytics/README.md @@ -0,0 +1,276 @@ +

It is typically used during the development and testing phase of a documentation project. + +```bash +mkdocs serve +``` + +Here is a breakdown of what this command does: + +- `mkdocs`: This is the command-line interface (CLI) for the MkDocs static site generator. It is used to build and serve MkDocs sites. +- `serve`: This is a subcommand of the `mkdocs` CLI that tells it to build and serve the documentation site locally. +- `-a`: This flag specifies the hostname and port number to bind the server to. The default value is `localhost:8000`. +- `-t`: This flag specifies the theme to use for the documentation site. The default value is `mkdocs`. +- `-s`: This flag tells the `serve` command to serve the site in silent mode, which means it will not display any log messages or progress updates. When you run the `mkdocs serve` command, it will build the documentation site using the files in the `docs/` directory and serve it at the specified hostname and port number. You can then view the site by going to the URL in your web browser. + +While the site is being served, you can make changes to the documentation files and see them reflected in the live site immediately.

Some popular options include GitHub Pages, GitLab Pages, and Amazon S3. + +Before you can deploy your site, you will need to configure your `mkdocs.yml` file to specify the remote host and any other necessary deployment settings. + +Once you have configured your `mkdocs.yml` file, you can use the `mkdocs deploy` command to build and deploy your site. This command will build the documentation site using the files in the `docs/` directory and the specified configuration file and theme, and then deploy the site to the specified remote host. + +For example, to deploy your site to GitHub Pages using the gh-deploy plugin, you can use the following command: + +```bash +mkdocs gh-deploy +``` + +If you are using GitHub Pages, you can set a custom domain for your documentation site by going to the "Settings" page for your repository and updating the "Custom domain" field in the "GitHub Pages" section. + +![196814117-fc16e711-d2be-4722-9536-b7c6d78fd167](https://user-images.githubusercontent.com/26833433/210150206-9e86dcd7-10af-43e4-9eb2-9518b3799eac.png) + +For more information on deploying your MkDocs documentation site, see the [MkDocs documentation](https://www.mkdocs.org/user-guide/deploying-your-docs/). diff --git a/ultralytics/docs/SECURITY.md b/ultralytics/docs/SECURITY.md new file mode 100644 index 0000000000000000000000000000000000000000..b7320e352d2e424c98a9adcf91e27ea6f064c350 --- /dev/null +++ b/ultralytics/docs/SECURITY.md @@ -0,0 +1,26 @@ +--- +description: Discover how Ultralytics ensures the safety of user data and systems.

While MNIST included images only of handwritten digits, EMNIST includes all the images from NIST Special Database 19, which is a large database of handwritten uppercase and lowercase letters as well as digits. The images in EMNIST were converted into the same 28x28 pixel format, by the same process, as were the MNIST images. Accordingly, tools that work with the older, smaller MNIST dataset will likely work unmodified with EMNIST. + +## Applications + +The MNIST dataset is widely used for training and evaluating deep learning models in image classification tasks, such as Convolutional Neural Networks (CNNs), Support Vector Machines (SVMs), and various other machine learning algorithms.

The training performance is then assessed. + +### Evaluate Model + +Use metrics like AP50, F1-score, or custom metrics to evaluate the model's performance. + +### Log Results + +It's crucial to log both the performance metrics and the corresponding hyperparameters for future reference. + +### Repeat + +The process is repeated until either the set number of iterations is reached or the performance metric is satisfactory. + +## Usage Example + +Here's how to use the `model.tune()` method to utilize the `Tuner` class for hyperparameter tuning of YOLOv8n on COCO8 for 30 epochs with an AdamW optimizer and skipping plotting, checkpointing and validation other than on final epoch for faster Tuning. + +!!! example "" + + === "Python" + + ```python + from ultralytics import YOLO + + # Initialize the YOLO model + model = YOLO('yolov8n.pt') + + # Tune hyperparameters on COCO8 for 30 epochs + model.tune(data='coco8.yaml', epochs=30, iterations=300, optimizer='AdamW', plots=False, save=False, val=False) + ``` + +## Results + +After you've successfully completed the hyperparameter tuning process, you will obtain several files and directories that encapsulate the results of the tuning. The following describes each: + +### File Structure + +Here's what the directory structure of the results will look like. Training directories like `train1/` contain individual tuning iterations, i.e. one model trained with one set of hyperparameters. The `tune/` directory contains tuning results from all the individual model trainings: + +```plaintext +runs/ +└── detect/ + ├── train1/ + ├── train2/ + ├── ... + └── tune/ + ├── best_hyperparameters.yaml + ├── best_fitness.png + ├── tune_results.csv + ├── tune_scatter_plots.png + └── weights/ + ├── last.pt + └── best.pt +``` + +### File Descriptions + +#### best_hyperparameters.yaml + +This YAML file contains the best-performing hyperparameters found during the tuning process.

+ K-Fold Cross Validation Overview +

+ +Whether your project involves the Fruit Detection dataset or a custom data source, this tutorial aims to help you comprehend and apply K-Fold Cross Validation to bolster the reliability and robustness of your machine learning models. While we're applying `k=5` folds for this tutorial, keep in mind that the optimal number of folds can vary depending on your dataset and the specifics of your project. + +Without further ado, let's dive in! + +## Setup + +- Your annotations should be in the [YOLO detection format](https://docs.ultralytics.com/datasets/detect/). + +- This guide assumes that annotation files are locally available. + + - For our demonstration, we use the [Fruit Detection](https://www.kaggle.com/datasets/lakshaytyagi01/fruit-detection/code) dataset. + + - This dataset contains a total of 8479 images. + - It includes 6 class labels, each with its total instance counts listed below. + + | Class Label | Instance Count | + |:------------|:--------------:| + | Apple | 7049 | + | Grapes | 7202 | + | Pineapple | 1613 | + | Orange | 15549 | + | Banana | 3536 | + | Watermelon | 1976 | + +- Necessary Python packages include: + + - `ultralytics` + - `sklearn` + - `pandas` + - `pyyaml` + +- This tutorial operates with `k=5` folds. However, you should determine the best number of folds for your specific dataset. + +1. Initiate a new Python virtual environment (`venv`) for your project and activate it. Use `pip` (or your preferred package manager) to install: + + - The Ultralytics library: `pip install -U ultralytics`. Alternatively, you can clone the official [repo](https://github.com/ultralytics/ultralytics). + - Scikit-learn, pandas, and PyYAML: `pip install -U scikit-learn pandas pyyaml`. + +2. Verify that your annotations are in the [YOLO detection format](https://docs.ultralytics.com/datasets/detect/). + + - For this tutorial, all annotation files are found in the `Fruit-Detection/labels` directory. + +## Generating Feature Vectors for Object Detection Dataset + +1. Start by creating a new Python file and import the required libraries. + + ```python + import datetime + import shutil + from pathlib import Path + from collections import Counter + + import yaml + import numpy as np + import pandas as pd + from ultralytics import YOLO + from sklearn.model_selection import KFold + ``` + +2. Proceed to retrieve all label files for your dataset. + + ```python + dataset_path = Path('./Fruit-detection') # replace with 'path/to/dataset' for your custom data + labels = sorted(dataset_path.rglob("*labels/*.txt")) # all data in 'labels' + ``` + +3. Now, read the contents of the dataset YAML file and extract the indices of the class labels. + + ```python + yaml_file = 'path/to/data.yaml' # your data YAML with data directories and names dictionary + with open(yaml_file, 'r', encoding="utf8") as y: + classes = yaml.safe_load(y)['names'] + cls_idx = sorted(classes.keys()) + ``` + +4. Initialize an empty `pandas` DataFrame. + + ```python + indx = [l.stem for l in labels] # uses base filename as ID (no extension) + labels_df = pd.DataFrame([], columns=cls_idx, index=indx) + ``` + +5. Count the instances of each class-label present in the annotation files. + + ```python + for label in labels: + lbl_counter = Counter() + + with open(label,'r') as lf: + lines = lf.readlines() + + for l in lines: + # classes for YOLO label uses integer at first position of each line + lbl_counter[int(l.split(' ')[0])] += 1 + + labels_df.loc[label.stem] = lbl_counter + + labels_df = labels_df.fillna(0.0) # replace `nan` values with `0.0` + ``` + +6. The following is a sample view of the populated DataFrame: + + ```pandas + 0 1 2 3 4 5 + '0000a16e4b057580_jpg.rf.00ab48988370f64f5ca8ea4...' 0.0 0.0 0.0 0.0 0.0 7.0 + '0000a16e4b057580_jpg.rf.7e6dce029fb67f01eb19aa7...' 0.0 0.0 0.0 0.0 0.0 7.0 + '0000a16e4b057580_jpg.rf.bc4d31cdcbe229dd022957a...' 0.0 0.0 0.0 0.0 0.0 7.0 + '00020ebf74c4881c_jpg.rf.508192a0a97aa6c4a3b6882...' 0.0 0.0 0.0 1.0 0.0 0.0 + '00020ebf74c4881c_jpg.rf.5af192a2254c8ecc4188a25...' 0.0 0.0 0.0 1.0 0.0 0.0 + ... ... ... ... ... ... ... + 'ff4cd45896de38be_jpg.rf.c4b5e967ca10c7ced3b9e97...' 0.0 0.0 0.0 0.0 0.0 2.0 + 'ff4cd45896de38be_jpg.rf.ea4c1d37d2884b3e3cbce08...' 0.0 0.0 0.0 0.0 0.0 2.0 + 'ff5fd9c3c624b7dc_jpg.rf.bb519feaa36fc4bf630a033...' 1.0 0.0 0.0 0.0 0.0 0.0 + 'ff5fd9c3c624b7dc_jpg.rf.f0751c9c3aa4519ea3c9d6a...' 1.0 0.0 0.0 0.0 0.0 0.0 + 'fffe28b31f2a70d4_jpg.rf.7ea16bd637ba0711c53b540...' 0.0 6.0 0.0 0.0 0.0 0.0 + ``` + +The rows index the label files, each corresponding to an image in your dataset, and the columns correspond to your class-label indices. Each row represents a pseudo feature-vector, with the count of each class-label present in your dataset. This data structure enables the application of K-Fold Cross Validation to an object detection dataset. + +## K-Fold Dataset Split + +1. Now we will use the `KFold` class from `sklearn.model_selection` to generate `k` splits of the dataset. + + - Important: + - Setting `shuffle=True` ensures a randomized distribution of classes in your splits. + - By setting `random_state=M` where `M` is a chosen integer, you can obtain repeatable results. + + ```python + ksplit = 5 + kf = KFold(n_splits=ksplit, shuffle=True, random_state=20) # setting random_state for repeatable results + + kfolds = list(kf.split(labels_df)) + ``` + +2. The dataset has now been split into `k` folds, each having a list of `train` and `val` indices. We will construct a DataFrame to display these results more clearly. + + ```python + folds = [f'split_{n}' for n in range(1, ksplit + 1)] + folds_df = pd.DataFrame(index=indx, columns=folds) + + for idx, (train, val) in enumerate(kfolds, start=1): + folds_df[f'split_{idx}'].loc[labels_df.iloc[train].index] = 'train' + folds_df[f'split_{idx}'].loc[labels_df.iloc[val].index] = 'val' + ``` + +3. Now we will calculate the distribution of class labels for each fold as a ratio of the classes present in `val` to those present in `train`. + + ```python + fold_lbl_distrb = pd.DataFrame(index=folds, columns=cls_idx) + + for n, (train_indices, val_indices) in enumerate(kfolds, start=1): + train_totals = labels_df.iloc[train_indices].sum() + val_totals = labels_df.iloc[val_indices].sum() + + # To avoid division by zero, we add a small value (1E-7) to the denominator + ratio = val_totals / (train_totals + 1E-7) + fold_lbl_distrb.loc[f'split_{n}'] = ratio + ``` + +The ideal scenario is for all class ratios to be reasonably similar for each split and across classes. This, however, will be subject to the specifics of your dataset. + +4. Next, we create the directories and dataset YAML files for each split. + + ```python + supported_extensions = ['.jpg', '.jpeg', '.png'] + + # Initialize an empty list to store image file paths + images = [] + + # Loop through supported extensions and gather image files + for ext in supported_extensions: + images.extend(sorted((dataset_path / 'images').rglob(f"*{ext}"))) + + # Create the necessary directories and dataset YAML files (unchanged) + save_path = Path(dataset_path / f'{datetime.date.today().isoformat()}_{ksplit}-Fold_Cross-val') + save_path.mkdir(parents=True, exist_ok=True) + ds_yamls = [] + + for split in folds_df.columns: + # Create directories + split_dir = save_path / split + split_dir.mkdir(parents=True, exist_ok=True) + (split_dir / 'train' / 'images').mkdir(parents=True, exist_ok=True) + (split_dir / 'train' / 'labels').mkdir(parents=True, exist_ok=True) + (split_dir / 'val' / 'images').mkdir(parents=True, exist_ok=True) + (split_dir / 'val' / 'labels').mkdir(parents=True, exist_ok=True) + + # Create dataset YAML files + dataset_yaml = split_dir / f'{split}_dataset.yaml' + ds_yamls.append(dataset_yaml) + + with open(dataset_yaml, 'w') as ds_y: + yaml.safe_dump({ + 'path': split_dir.as_posix(), + 'train': 'train', + 'val': 'val', + 'names': classes + }, ds_y) + ``` + +5. Lastly, copy images and labels into the respective directory ('train' or 'val') for each split. + + - __NOTE:__ The time required for this portion of the code will vary based on the size of your dataset and your system hardware. + + ```python + for image, label in zip(images, labels): + for split, k_split in folds_df.loc[image.stem].items(): + # Destination directory + img_to_path = save_path / split / k_split / 'images' + lbl_to_path = save_path / split / k_split / 'labels' + + # Copy image and label files to new directory (SamefileError if file already exists) + shutil.copy(image, img_to_path / image.name) + shutil.copy(label, lbl_to_path / label.name) + ``` + +## Save Records (Optional) + +Optionally, you can save the records of the K-Fold split and label distribution DataFrames as CSV files for future reference. + +```python +folds_df.to_csv(save_path / "kfold_datasplit.csv") +fold_lbl_distrb.to_csv(save_path / "kfold_label_distribution.csv") +``` + +## Train YOLO using K-Fold Data Splits + +1. First, load the YOLO model. + + ```python + weights_path = 'path/to/weights.pt' + model = YOLO(weights_path, task='detect') + ``` + +2. Next, iterate over the dataset YAML files to run training. The results will be saved to a directory specified by the `project` and `name` arguments. By default, this directory is 'exp/runs#' where # is an integer index. + + ```python + results = {} + + # Define your additional arguments here + batch = 16 + project = 'kfold_demo' + epochs = 100 + + for k in range(ksplit): + dataset_yaml = ds_yamls[k] + model.train(data=dataset_yaml,epochs=epochs, batch=batch, project=project) # include any train arguments + results[k] = model.metrics # save output metrics for further analysis + ``` + +## Conclusion + +In this guide, we have explored the process of using K-Fold cross-validation for training the YOLO object detection model. We learned how to split our dataset into K partitions, ensuring a balanced class distribution across the different folds. + +We also explored the procedure for creating report DataFrames to visualize the data splits and label distributions across these splits, providing us a clear insight into the structure of our training and validation sets. + +Optionally, we saved our records for future reference, which could be particularly useful in large-scale projects or when troubleshooting model performance. + +Finally, we implemented the actual model training using each split in a loop, saving our training results for further analysis and comparison. + +This technique of K-Fold cross-validation is a robust way of making the most out of your available data, and it helps to ensure that your model performance is reliable and consistent across different data subsets. This results in a more generalizable and reliable model that is less likely to overfit to specific data patterns. + +Remember that although we used YOLO in this guide, these steps are mostly transferable to other machine learning models. Understanding these steps allows you to apply cross-validation effectively in your own machine learning projects.

+ SAHI Sliced Inference Overview +

+ +## Introduction to SAHI + +SAHI (Slicing Aided Hyper Inference) is an innovative library designed to optimize object detection algorithms for large-scale and high-resolution imagery. Its core functionality lies in partitioning images into manageable slices, running object detection on each slice, and then stitching the results back together. SAHI is compatible with a range of object detection models, including the YOLO series, thereby offering flexibility while ensuring optimized use of computational resources. + +### Key Features of SAHI + +- **Seamless Integration**: SAHI integrates effortlessly with YOLO models, meaning you can start slicing and detecting without a lot of code modification. +- **Resource Efficiency**: By breaking down large images into smaller parts, SAHI optimizes the memory usage, allowing you to run high-quality detection on hardware with limited resources. +- **High Accuracy**: SAHI maintains the detection accuracy by employing smart algorithms to merge overlapping detection boxes during the stitching process. + +## What is Sliced Inference? + +Sliced Inference refers to the practice of subdividing a large or high-resolution image into smaller segments (slices), conducting object detection on these slices, and then recompiling the slices to reconstruct the object locations on the original image. This technique is invaluable in scenarios where computational resources are limited or when working with extremely high-resolution images that could otherwise lead to memory issues. + +### Benefits of Sliced Inference + +- **Reduced Computational Burden**: Smaller image slices are faster to process, and they consume less memory, enabling smoother operation on lower-end hardware. + +- **Preserved Detection Quality**: Since each slice is treated independently, there is no reduction in the quality of object detection, provided the slices are large enough to capture the objects of interest. + +- **Enhanced Scalability**: The technique allows for object detection to be more easily scaled across different sizes and resolutions of images, making it ideal for a wide range of applications from satellite imagery to medical diagnostics. + + + + + + + + + + +

+ +## What is Triton Inference Server? + +Triton Inference Server is designed to deploy a variety of AI models in production. It supports a wide range of deep learning and machine learning frameworks, including TensorFlow, PyTorch, ONNX Runtime, and many others. Its primary use cases are: + +- Serving multiple models from a single server instance. +- Dynamic model loading and unloading without server restart. +- Ensemble inferencing, allowing multiple models to be used together to achieve results. +- Model versioning for A/B testing and rolling updates. + +## Prerequisites + +Ensure you have the following prerequisites before proceeding: + +- Docker installed on your machine. +- Install `tritonclient`: + ```bash + pip install tritonclient[all] + ``` + +## Exporting YOLOv8 to ONNX Format + +Before deploying the model on Triton, it must be exported to the ONNX format. ONNX (Open Neural Network Exchange) is a format that allows models to be transferred between different deep learning frameworks. Use the `export` function from the `YOLO` class: + +```python +from ultralytics import YOLO + +# Load a model +model = YOLO('yolov8n.pt') # load an official model + +# Export the model +onnx_file = model.export(format='onnx', dynamic=True) +``` + +## Setting Up Triton Model Repository + +The Triton Model Repository is a storage location where Triton can access and load models. + +1. Create the necessary directory structure: + + ```python + from pathlib import Path + + # Define paths + triton_repo_path = Path('tmp') / 'triton_repo' + triton_model_path = triton_repo_path / 'yolo' + + # Create directories + (triton_model_path / '1').mkdir(parents=True, exist_ok=True) + ``` + +2. Move the exported ONNX model to the Triton repository: + + ```python + from pathlib import Path + + # Move ONNX model to Triton Model path + Path(onnx_file).rename(triton_model_path / '1' / 'model.onnx') + + # Create config file + (triton_model_path / 'config.pdtxt').touch() + ``` + +## Running Triton Inference Server + +Run the Triton Inference Server using Docker: + +```python +import subprocess +import time + +from tritonclient.http import InferenceServerClient + +# Define image https://catalog.ngc.nvidia.com/orgs/nvidia/containers/tritonserver +tag = 'nvcr.io/nvidia/tritonserver:23.09-py3' # 6.4 GB + +# Pull the image +subprocess.call(f'docker pull {tag}', shell=True) + +# Run the Triton server and capture the container ID +container_id = subprocess.check_output( + f'docker run -d --rm -v {triton_repo_path}:/models -p 8000:8000 {tag} tritonserver --model-repository=/models', + shell=True).decode('utf-8').strip() + +# Wait for the Triton server to start +triton_client = InferenceServerClient(url='localhost:8000', verbose=False, ssl=False) + +# Wait until model is ready +for _ in range(10): + with contextlib.suppress(Exception): + assert triton_client.is_model_ready(model_name) + break + time.sleep(1) +``` + +Then run inference using the Triton Server model: + +```python +from ultralytics import YOLO + +# Load the Triton Server model +model = YOLO(f'http://localhost:8000/yolo', task='detect') + +# Run inference on the server +results = model('path/to/image.jpg') +``` + +Cleanup the container: + +```python +# Kill and remove the container at the end of the test +subprocess.call(f'docker kill {container_id}', shell=True) +``` + +--- + +By following the above steps, you can deploy and run Ultralytics YOLOv8 models efficiently on Triton Inference Server, providing a scalable and high-performance solution for deep learning inference tasks.

Use the `nvidia-smi` command to check the status of your NVIDIA GPU and CUDA version. + + - **Check PyTorch and CUDA Integration**: Ensure PyTorch can utilize CUDA by running `import torch; print(torch.cuda.is_available())` in a Python terminal. If it returns 'True', PyTorch is set up to use CUDA. + + - **Environment Activation**: Ensure you're in the correct environment where all necessary packages are installed. + + - **Update Your Packages**: Outdated packages might not be compatible with your GPU. Keep them updated. + + - **Program Configuration**: Check if the program or code specifies GPU usage. In YOLOv8, this might be in the settings or configuration. + +### Model Training Issues + +This section will address common issues faced while training and their respective explanations and solutions. + +#### Verification of Configuration Settings + +**Issue**: You are unsure whether the configuration settings in the `.yaml` file are being applied correctly during model training. + +**Solution**: The configuration settings in the `.yaml` file should be applied when using the `model.train()` function. To ensure that these settings are correctly applied, follow these steps: + +- Confirm that the path to your `.yaml` configuration file is correct. +- Make sure you pass the path to your `.yaml` file as the `data` argument when calling `model.train()`, as shown below: + +```python +model.train(data='/path/to/your/data.yaml', batch=4) +``` + +#### Accelerating Training with Multiple GPUs + +**Issue**: Training is slow on a single GPU, and you want to speed up the process using multiple GPUs. + +**Solution**: Increasing the batch size can accelerate training, but it's essential to consider GPU memory capacity. To speed up training with multiple GPUs, follow these steps: + +- Ensure that you have multiple GPUs available. + +- Modify your .yaml configuration file to specify the number of GPUs to use, e.g., gpus: 4. + +- Increase the batch size accordingly to fully utilize the multiple GPUs without exceeding memory limits. + +- Modify your training command to utilize multiple GPUs: + +```python +# Adjust the batch size and other settings as needed to optimize training speed +model.train(data='/path/to/your/data.yaml', batch=32, multi_scale=True) +``` + +#### Continuous Monitoring Parameters + +**Issue**: You want to know which parameters should be continuously monitored during training, apart from loss. + +**Solution**: While loss is a crucial metric to monitor, it's also essential to track other metrics for model performance optimization. Some key metrics to monitor during training include: + +- Precision +- Recall +- Mean Average Precision (mAP) + +You can access these metrics from the training logs or by using tools like TensorBoard or wandb for visualization. Implementing early stopping based on these metrics can help you achieve better results. + +#### Tools for Tracking Training Progress + +**Issue**: You are looking for recommendations on tools to track training progress. + +**Solution**: To track and visualize training progress, you can consider using the following tools: + +- [TensorBoard](https://www.tensorflow.org/tensorboard): TensorBoard is a popular choice for visualizing training metrics, including loss, accuracy, and more. You can integrate it with your YOLOv8 training process. +- [Comet](https://bit.ly/yolov8-readme-comet): Comet provides an extensive toolkit for experiment tracking and comparison. It allows you to track metrics, hyperparameters, and even model weights. Integration with YOLO models is also straightforward, providing you with a complete overview of your experiment cycle. +- [Ultralytics HUB](https://hub.ultralytics.com): Ultralytics HUB offers a specialized environment for tracking YOLO models, giving you a one-stop platform to manage metrics, datasets, and even collaborate with your team. Given its tailored focus on YOLO, it offers more customized tracking options. + +Each of these tools offers its own set of advantages, so you may want to consider the specific needs of your project when making a choice. + +#### How to Check if Training is Happening on the GPU + +**Issue**: The 'device' value in the training logs is 'null,' and you're unsure if training is happening on the GPU. + +**Solution**: The 'device' value being 'null' typically means that the training process is set to automatically use an available GPU, which is the default behavior. To ensure training occurs on a specific GPU, you can manually set the 'device' value to the GPU index (e.g., '0' for the first GPU) in your .yaml configuration file: + +```yaml +device: 0 +``` + +This will explicitly assign the training process to the specified GPU. If you wish to train on the CPU, set 'device' to 'cpu'. + +Keep an eye on the 'runs' folder for logs and metrics to monitor training progress effectively. + +#### Key Considerations for Effective Model Training + +Here are some things to keep in mind, if you are facing issues related to model training. + +**Dataset Format and Labels** + +- Importance: The foundation of any machine learning model lies in the quality and format of the data it is trained on. + +- Recommendation: Ensure that your custom dataset and its associated labels adhere to the expected format. It's crucial to verify that annotations are accurate and of high quality. Incorrect or subpar annotations can derail the model's learning process, leading to unpredictable outcomes. + +**Model Convergence** + +- Importance: Achieving model convergence ensures that the model has sufficiently learned from the training data. + +- Recommendation: When training a model 'from scratch', it's vital to ensure that the model reaches a satisfactory level of convergence. This might necessitate a longer training duration, with more epochs, compared to when you're fine-tuning an existing model. + +**Learning Rate and Batch Size** + +- Importance: These hyperparameters play a pivotal role in determining how the model updates its weights during training. + +- Recommendation: Regularly evaluate if the chosen learning rate and batch size are optimal for your specific dataset. Parameters that are not in harmony with the dataset's characteristics can hinder the model's performance. + +**Class Distribution** + +- Importance: The distribution of classes in your dataset can influence the model's prediction tendencies. + +- Recommendation: Regularly assess the distribution of classes within your dataset. If there's a class imbalance, there's a risk that the model will develop a bias towards the more prevalent class. This bias can be evident in the confusion matrix, where the model might predominantly predict the majority class. + +**Cross-Check with Pretrained Weights** + +- Importance: Leveraging pretrained weights can provide a solid starting point for model training, especially when data is limited. + +- Recommendation: As a diagnostic step, consider training your model using the same data but initializing it with pretrained weights. If this approach yields a well-formed confusion matrix, it could suggest that the 'from scratch' model might require further training or adjustments. + +### Issues Related to Model Predictions + +This section will address common issues faced during model prediction. + +#### Getting Bounding Box Predictions With Your YOLOv8 Custom Model + +**Issue**: When running predictions with a custom YOLOv8 model, there are challenges with the format and visualization of the bounding box coordinates. + +**Solution**: + +- Coordinate Format: YOLOv8 provides bounding box coordinates in absolute pixel values. To convert these to relative coordinates (ranging from 0 to 1), you need to divide by the image dimensions. For example, let’s say your image size is 640x640. Then you would do the following: + +```python +# Convert absolute coordinates to relative coordinates +x1 = x1 / 640 # Divide x-coordinates by image width +x2 = x2 / 640 +y1 = y1 / 640 # Divide y-coordinates by image height +y2 = y2 / 640 +``` + +- File Name: To obtain the file name of the image you're predicting on, access the image file path directly from the result object within your prediction loop. + +#### Filtering Objects in YOLOv8 Predictions + +**Issue**: Facing issues with how to filter and display only specific objects in the prediction results when running YOLOv8 using the Ultralytics library. + +**Solution**: To detect specific classes use the classes argument to specify the classes you want to include in the output. For instance, to detect only cars (assuming 'cars' have class index 2): + +```shell +yolo task=detect mode=segment model=yolov8n-seg.pt source='path/to/car.mp4' show=True classes=2 +``` + +#### Understanding Precision Metrics in YOLOv8 + +**Issue**: Confusion regarding the difference between box precision, mask precision, and confusion matrix precision in YOLOv8. + +**Solution**: Box precision measures the accuracy of predicted bounding boxes compared to the actual ground truth boxes using IoU (Intersection over Union) as the metric. Mask precision assesses the agreement between predicted segmentation masks and ground truth masks in pixel-wise object classification. Confusion matrix precision, on the other hand, focuses on overall classification accuracy across all classes and does not consider the geometric accuracy of predictions. It's important to note that a bounding box can be geometrically accurate (true positive) even if the class prediction is wrong, leading to differences between box precision and confusion matrix precision. These metrics evaluate distinct aspects of a model's performance, reflecting the need for different evaluation metrics in various tasks. + +#### Extracting Object Dimensions in YOLOv8 + +**Issue**: Difficulty in retrieving the length and height of detected objects in YOLOv8, especially when multiple objects are detected in an image. + +**Solution**: To retrieve the bounding box dimensions, first use the Ultralytics YOLOv8 model to predict objects in an image. Then, extract the width and height information of bounding boxes from the prediction results. + +```python +from ultralytics import YOLO + +# Load a pre-trained YOLOv8 model +model = YOLO('yolov8n.pt') + +# Specify the source image +source = 'https://ultralytics.com/images/bus.jpg' + +# Make predictions +results = model.predict(source, save=True, imgsz=320, conf=0.5) + +# Extract bounding box dimensions +boxes = results[0].boxes.xywh.cpu() +for box in boxes: + x, y, w, h = box + print(f"Width of Box: {w}, Height of Box: {h}") +``` + +### Deployment Challenges + +#### GPU Deployment Issues + +**Issue:** Deploying models in a multi-GPU environment can sometimes lead to unexpected behaviors like unexpected memory usage, inconsistent results across GPUs, etc. + +**Solution:** Check for default GPU initialization. Some frameworks, like PyTorch, might initialize CUDA operations on a default GPU before transitioning to the designated GPUs. To bypass unexpected default initializations, specify the GPU directly during deployment and prediction. Then, use tools to monitor GPU utilization and memory usage to identify any anomalies in real-time. Also, ensure you're using the latest version of the framework or library. + +#### Model Conversion/Exporting Issues + +**Issue:** During the process of converting or exporting machine learning models to different formats or platforms, users might encounter errors or unexpected behaviors. + +**Solution:** + +- Compatibility Check: Ensure that you are using versions of libraries and frameworks that are compatible with each other. Mismatched versions can lead to unexpected errors during conversion. + +- Environment Reset: If you're using an interactive environment like Jupyter or Colab, consider restarting your environment after making significant changes or installations. A fresh start can sometimes resolve underlying issues. + +- Official Documentation: Always refer to the official documentation of the tool or library you are using for conversion. It often contains specific guidelines and best practices for model exporting. + +- Community Support: Check the library or framework's official repository for similar issues reported by other users. The maintainers or community might have provided solutions or workarounds in discussion threads. + +- Update Regularly: Ensure that you are using the latest version of the tool or library. Developers frequently release updates that fix known bugs or improve functionality. + +- Test Incrementally: Before performing a full conversion, test the process with a smaller model or dataset to identify potential issues early on. + +## Community and Support + +Engaging with a community of like-minded individuals can significantly enhance your experience and success in working with YOLOv8.

They shed light on how effectively a model can identify and localize objects within images. Additionally, they help in understanding the model's handling of false positives and false negatives. These insights are crucial for evaluating and enhancing the model's performance. In this guide, we will explore various performance metrics associated with YOLOv8, their significance, and how to interpret them. + +## Object Detection Metrics + +Let’s start by discussing some metrics that are not only important to YOLOv8 but are broadly applicable across different object detection models. + +- **Intersection over Union (IoU):** IoU is a measure that quantifies the overlap between a predicted bounding box and a ground truth bounding box. It plays a fundamental role in evaluating the accuracy of object localization. + +- **Average Precision (AP):** AP computes the area under the precision-recall curve, providing a single value that encapsulates the model's precision and recall performance. + +- **Mean Average Precision (mAP):** mAP extends the concept of AP by calculating the average AP values across multiple object classes. This is useful in multi-class object detection scenarios to provide a comprehensive evaluation of the model's performance. + +- **Precision and Recall:** Precision quantifies the proportion of true positives among all positive predictions, assessing the model's capability to avoid false positives. On the other hand, Recall calculates the proportion of true positives among all actual positives, measuring the model's ability to detect all instances of a class. + +- **F1 Score:** The F1 Score is the harmonic mean of precision and recall, providing a balanced assessment of a model's performance while considering both false positives and false negatives. + +## How to Calculate Metrics for YOLOv8 Model + +Now, we can explore [YOLOv8's Validation mode](https://docs.ultralytics.com/modes/val/) that can be used to compute the above discussed evaluation metrics. + +Using the validation mode is simple. Once you have a trained model, you can invoke the model.val() function. This function will then process the validation dataset and return a variety of performance metrics. But what do these metrics mean? And how should you interpret them? + +### Interpreting the Output + +Let's break down the output of the model.val() function and understand each segment of the output. + +#### Class-wise Metrics + +One of the sections of the output is the class-wise breakdown of performance metrics. This granular information is useful when you are trying to understand how well the model is doing for each specific class, especially in datasets with a diverse range of object categories. For each class in the dataset the following is provided: + +- **Class**: This denotes the name of the object class, such as "person", "car", or "dog". + +- **Images**: This metric tells you the number of images in the validation set that contain the object class. + +- **Instances**: This provides the count of how many times the class appears across all images in the validation set. + +- **Box(P, R, mAP50, mAP50-95)**: This metric provides insights into the model's performance in detecting objects: + + - **P (Precision)**: The accuracy of the detected objects, indicating how many detections were correct. + + - **R (Recall)**: The ability of the model to identify all instances of objects in the images. + + - **mAP50**: Mean average precision calculated at an intersection over union (IoU) threshold of 0.50. It's a measure of the model's accuracy considering only the "easy" detections. + + - **mAP50-95**: The average of the mean average precision calculated at varying IoU thresholds, ranging from 0.50 to 0.95. It gives a comprehensive view of the model's performance across different levels of detection difficulty. + +#### Speed Metrics + +The speed of inference can be as critical as accuracy, especially in real-time object detection scenarios. This section breaks down the time taken for various stages of the validation process, from preprocessing to post-processing. + +#### COCO Metrics Evaluation + +For users validating on the COCO dataset, additional metrics are calculated using the COCO evaluation script. These metrics give insights into precision and recall at different IoU thresholds and for objects of different sizes. + +#### Visual Outputs + +The model.val() function, apart from producing numeric metrics, also yields visual outputs that can provide a more intuitive understanding of the model's performance. Here's a breakdown of the visual outputs you can expect: + +- **F1 Score Curve (`F1_curve.png`)**: This curve represents the F1 score across various thresholds. Interpreting this curve can offer insights into the model's balance between false positives and false negatives over different thresholds. + +- **Precision-Recall Curve (`PR_curve.png`)**: An integral visualization for any classification problem, this curve showcases the trade-offs between precision and recall at varied thresholds. It becomes especially significant when dealing with imbalanced classes. + +- **Precision Curve (`P_curve.png`)**: A graphical representation of precision values at different thresholds. This curve helps in understanding how precision varies as the threshold changes. + +- **Recall Curve (`R_curve.png`)**: Correspondingly, this graph illustrates how the recall values change across different thresholds. + +- **Confusion Matrix (`confusion_matrix.png`)**: The confusion matrix provides a detailed view of the outcomes, showcasing the counts of true positives, true negatives, false positives, and false negatives for each class. + +- **Normalized Confusion Matrix (`confusion_matrix_normalized.png`)**: This visualization is a normalized version of the confusion matrix. It represents the data in proportions rather than raw counts. This format makes it simpler to compare the performance across classes. + +- **Validation Batch Labels (`val_batchX_labels.jpg`)**: These images depict the ground truth labels for distinct batches from the validation dataset. They provide a clear picture of what the objects are and their respective locations as per the dataset. + +- **Validation Batch Predictions (`val_batchX_pred.jpg`)**: Contrasting the label images, these visuals display the predictions made by the YOLOv8 model for the respective batches. By comparing these to the label images, you can easily assess how well the model detects and classifies objects visually. + +#### Results Storage + +For future reference, the results are saved to a directory, typically named runs/detect/val. + +## Choosing the Right Metrics + +Choosing the right metrics to evaluate often depends on the specific application. + +- **mAP:** Suitable for a broad assessment of model performance. + +- **IoU:** Essential when precise object location is crucial. + +- **Precision:** Important when minimizing false detections is a priority. + +- **Recall:** Vital when it's important to detect every instance of an object. + +- **F1 Score:** Useful when a balance between precision and recall is needed. + +For real-time applications, speed metrics like FPS (Frames Per Second) and latency are crucial to ensure timely results. + +## Interpretation of Results + +It’s important to understand the metrics. Here's what some of the commonly observed lower scores might suggest: + +- **Low mAP:** Indicates the model may need general refinements. + +- **Low IoU:** The model might be struggling to pinpoint objects accurately. Different bounding box methods could help. + +- **Low Precision:** The model may be detecting too many non-existent objects. Adjusting confidence thresholds might reduce this. + +- **Low Recall:** The model could be missing real objects. Improving feature extraction or using more data might help. + +- **Imbalanced F1 Score:** There's a disparity between precision and recall. + +- **Class-specific AP:** Low scores here can highlight classes the model struggles with. + +## Case Studies + +Real-world examples can help clarify how these metrics work in practice. + +### Case 1 + +- **Situation:** mAP and F1 Score are suboptimal, but while Recall is good, Precision isn't. + +- **Interpretation & Action:** There might be too many incorrect detections. Tightening confidence thresholds could reduce these, though it might also slightly decrease recall. + +### Case 2 + +- **Situation:** mAP and Recall are acceptable, but IoU is lacking. + +- **Interpretation & Action:** The model detects objects well but might not be localizing them precisely. Refining bounding box predictions might help. + +### Case 3 + +- **Situation:** Some classes have a much lower AP than others, even with a decent overall mAP. + +- **Interpretation & Action:** These classes might be more challenging for the model. Using more data for these classes or adjusting class weights during training could be beneficial. + +## Connect and Collaborate + +Tapping into a community of enthusiasts and experts can amplify your journey with YOLOv8. Here are some avenues that can facilitate learning, troubleshooting, and networking. + +### Engage with the Broader Community + +- **GitHub Issues:** The YOLOv8 repository on GitHub has an [Issues tab](https://github.com/ultralytics/ultralytics/issues) where you can ask questions, report bugs, and suggest new features.

Here is what you should avoid: sharing a single YOLO model instance across multiple threads. + +```python +# Unsafe: Sharing a single model instance across threads +from ultralytics import YOLO +from threading import Thread + +# Instantiate the model outside the thread +shared_model = YOLO("yolov8n.pt") + + +def predict(image_path): + results = shared_model.predict(image_path) + # Process results + + +# Starting threads that share the same model instance +Thread(target=predict, args=("image1.jpg",)).start() +Thread(target=predict, args=("image2.jpg",)).start() +``` + +In the example above, the `shared_model` is used by multiple threads, which can lead to unpredictable results because `predict` could be executed simultaneously by multiple threads. + +### Non-Thread-Safe Example: Multiple Model Instances + +Similarly, here is an unsafe pattern with multiple YOLO model instances: + +```python +# Unsafe: Sharing multiple model instances across threads can still lead to issues +from ultralytics import YOLO +from threading import Thread + +# Instantiate multiple models outside the thread +shared_model_1 = YOLO("yolov8n_1.pt") +shared_model_2 = YOLO("yolov8n_2.pt") + + +def predict(model, image_path): + results = model.predict(image_path) + # Process results + + +# Starting threads with individual model instances +Thread(target=predict, args=(shared_model_1, "image1.jpg")).start() +Thread(target=predict, args=(shared_model_2, "image2.jpg")).start() +``` + +Even though there are two separate model instances, the risk of concurrency issues still exists. If the internal implementation of `YOLO` is not thread-safe, using separate instances might not prevent race conditions, especially if these instances share any underlying resources or states that are not thread-local. + +## Thread-Safe Inference + +To perform thread-safe inference, you should instantiate a separate YOLO model within each thread. This ensures that each thread has its own isolated model instance, eliminating the risk of race conditions. + +### Thread-Safe Example + +Here's how to instantiate a YOLO model inside each thread for safe parallel inference: + +```python +# Safe: Instantiating a single model inside each thread +from ultralytics import YOLO +from threading import Thread + + +def thread_safe_predict(image_path): + # Instantiate a new model inside the thread + local_model = YOLO("yolov8n.pt") + results = local_model.predict(image_path) + # Process results + + +# Starting threads that each have their own model instance +Thread(target=thread_safe_predict, args=("image1.jpg",)).start() +Thread(target=thread_safe_predict, args=("image2.jpg",)).start() +``` + +In this example, each thread creates its own `YOLO` instance. This prevents any thread from interfering with the model state of another, thus ensuring that each thread performs inference safely and without unexpected interactions with the other threads. + +## Conclusion + +When using YOLO models with Python's `threading`, always instantiate your models within the thread that will use them to ensure thread safety. This practice avoids race conditions and makes sure that your inference tasks run reliably. + +For more advanced scenarios and to further optimize your multi-threaded inference performance, consider using process-based parallelism with `multiprocessing` or leveraging a task queue with dedicated worker processes. diff --git a/ultralytics/docs/help/CI.md b/ultralytics/docs/help/CI.md new file mode 100644 index 0000000000000000000000000000000000000000..60cd01e39123def77c61ad5f2327db4ff71d0475 --- /dev/null +++ b/ultralytics/docs/help/CI.md @@ -0,0 +1,61 @@ +--- +comments: true +description: Learn how Ultralytics leverages Continuous Integration (CI) for maintaining high-quality code.

What are the hardware requirements for running Ultralytics YOLO? + +Ultralytics YOLO can be run on a variety of hardware configurations, including CPUs, GPUs, and even some edge devices. However, for optimal performance and faster training and inference, we recommend using a GPU with a minimum of 8GB of memory. NVIDIA GPUs with CUDA support are ideal for this purpose. + +## 2. How do I fine-tune a pre-trained YOLO model on my custom dataset? + +To fine-tune a pre-trained YOLO model on your custom dataset, you'll need to create a dataset configuration file (YAML) that defines the dataset's properties, such as the path to the images, the number of classes, and class names. Next, you'll need to modify the model configuration file to match the number of classes in your dataset. Finally, use the `train.py` script to start the training process with your custom dataset and the pre-trained model. You can find a detailed guide on fine-tuning YOLO in the Ultralytics documentation. + +## 3. How do I convert a YOLO model to ONNX or TensorFlow format? + +Ultralytics provides built-in support for converting YOLO models to ONNX format. You can use the `export.py` script to convert a saved model to ONNX format. If you need to convert the model to TensorFlow format, you can use the ONNX model as an intermediary and then use the ONNX-TensorFlow converter to convert the ONNX model to TensorFlow format. + +## 4. Can I use Ultralytics YOLO for real-time object detection? + +Yes, Ultralytics YOLO is designed to be efficient and fast, making it suitable for real-time object detection tasks. The actual performance will depend on your hardware configuration and the complexity of the model. Using a GPU and optimizing the model for your specific use case can help achieve real-time performance. + +## 5. How can I improve the accuracy of my YOLO model? + +Improving the accuracy of a YOLO model may involve several strategies, such as: + +- Fine-tuning the model on more annotated data +- Data augmentation to increase the variety of training samples +- Using a larger or more complex model architecture +- Adjusting the learning rate, batch size, and other hyperparameters +- Using techniques like transfer learning or knowledge distillation + +Remember that there's often a trade-off between accuracy and inference speed, so finding the right balance is crucial for your specific application. + +If you have any more questions or need assistance, don't hesitate to consult the Ultralytics documentation or reach out to the community through GitHub Issues or the official discussion forum. diff --git a/ultralytics/docs/help/code_of_conduct.md b/ultralytics/docs/help/code_of_conduct.md new file mode 100644 index 0000000000000000000000000000000000000000..c8c7cdc66ed90843164fbf40c3dfc63007feabd4 --- /dev/null +++ b/ultralytics/docs/help/code_of_conduct.md @@ -0,0 +1,88 @@ +--- +comments: true +description: Explore Ultralytics community’s Code of Conduct, ensuring a supportive, inclusive environment for contributors & members at all levels.

An MRE is a small, self-contained piece of code that demonstrates the problem you're experiencing. Providing an MRE helps maintainers and contributors understand the issue and work on a fix more efficiently. This guide explains how to create an MRE when submitting bug reports to Ultralytics YOLO repositories. + +## 1. Isolate the Problem + +The first step in creating an MRE is to isolate the problem. This means removing any unnecessary code or dependencies that are not directly related to the issue. Focus on the specific part of the code that is causing the problem and remove any irrelevant code. + +## 2. Use Public Models and Datasets + +When creating an MRE, use publicly available models and datasets to reproduce the issue. For example, use the 'yolov8n.pt' model and the 'coco8.yaml' dataset. This ensures that the maintainers and contributors can easily run your example and investigate the problem without needing access to proprietary data or custom models. + +## 3. Include All Necessary Dependencies + +Make sure to include all the necessary dependencies in your MRE. If your code relies on external libraries, specify the required packages and their versions. Ideally, provide a `requirements.txt` file or list the dependencies in your bug report. + +## 4. Write a Clear Description of the Issue + +Provide a clear and concise description of the issue you're experiencing. Explain the expected behavior and the actual behavior you're encountering. If applicable, include any relevant error messages or logs. + +## 5. Format Your Code Properly + +When submitting an MRE, format your code properly using code blocks in the issue description. This makes it easier for others to read and understand your code. In GitHub, you can create a code block by wrapping your code with triple backticks (\```) and specifying the language: + +
+```python
+# Your Python code goes here
+```
+
+ +## 6. Test Your MRE + +Before submitting your MRE, test it to ensure that it accurately reproduces the issue. Make sure that others can run your example without any issues or modifications. + +## Example of an MRE + +Here's an example of an MRE for a hypothetical bug report: + +**Bug description:** + +When running the `detect.py` script on the sample image from the 'coco8.yaml' dataset, I get an error related to the dimensions of the input tensor. + +**MRE:** + +```python +import torch +from ultralytics import YOLO + +# Load the model +model = YOLO("yolov8n.pt") + +# Load a 0-channel image +image = torch.rand(1, 0, 640, 640) + +# Run the model +results = model(image) +``` + +**Error message:** + +``` +RuntimeError: Expected input[1, 0, 640, 640] to have 3 channels, but got 0 channels instead +``` + +**Dependencies:** + +- torch==2.0.0 +- ultralytics==8.0.90 + +In this example, the MRE demonstrates the issue with a minimal amount of code, uses a public model ('yolov8n.pt'), includes all necessary dependencies, and provides a clear description of the problem along with the error message. + +By following these guidelines, you'll help the maintainers and contributors of Ultralytics YOLO repositories to understand and resolve your issue more efficiently. diff --git a/ultralytics/docs/help/privacy.md b/ultralytics/docs/help/privacy.md new file mode 100644 index 0000000000000000000000000000000000000000..dfd8137ef562ca0a6f5422854b77950dfde425b2 --- /dev/null +++ b/ultralytics/docs/help/privacy.md @@ -0,0 +1,137 @@ +--- +description: Learn about how Ultralytics collects and uses data to improve user experience, ensure software stability, and address privacy concerns, with options to opt-out. +keywords: Ultralytics, Data Collection, User Privacy, Google Analytics, Sentry, Crash Reporting, Anonymized Data, Privacy Settings, Opt-Out +--- + +# Data Collection for Ultralytics Python Package + +## Overview + +[Ultralytics](https://ultralytics.com) is dedicated to the continuous enhancement of the user experience and the capabilities of our Python package, including the advanced YOLO models we develop.

+ +The Ultralytics Android App is a powerful tool that allows you to run YOLO models directly on your Android device for real-time object detection. This app utilizes TensorFlow Lite for model optimization and various hardware delegates for acceleration, enabling fast and efficient object detection. + +## Quantization and Acceleration + +To achieve real-time performance on your Android device, YOLO models are quantized to either FP16 or INT8 precision. Quantization is a process that reduces the numerical precision of the model's weights and biases, thus reducing the model's size and the amount of computation required. This results in faster inference times without significantly affecting the model's accuracy. + +### FP16 Quantization + +FP16 (or half-precision) quantization converts the model's 32-bit floating-point numbers to 16-bit floating-point numbers. This reduces the model's size by half and speeds up the inference process, while maintaining a good balance between accuracy and performance. + +### INT8 Quantization + +INT8 (or 8-bit integer) quantization further reduces the model's size and computation requirements by converting its 32-bit floating-point numbers to 8-bit integers. This quantization method can result in a significant speedup, but it may lead to a slight reduction in mean average precision (mAP) due to the lower numerical precision. + +!!! tip "mAP Reduction in INT8 Models" + + The reduced numerical precision in INT8 models can lead to some loss of information during the quantization process, which may result in a slight decrease in mAP. However, this trade-off is often acceptable considering the substantial performance gains offered by INT8 quantization. + +## Delegates and Performance Variability + +Different delegates are available on Android devices to accelerate model inference. These delegates include CPU, [GPU](https://www.tensorflow.org/lite/android/delegates/gpu), [Hexagon](https://www.tensorflow.org/lite/android/delegates/hexagon) and [NNAPI](https://www.tensorflow.org/lite/android/delegates/nnapi). The performance of these delegates varies depending on the device's hardware vendor, product line, and specific chipsets used in the device. + +1. **CPU**: The default option, with reasonable performance on most devices. +2. **GPU**: Utilizes the device's GPU for faster inference. It can provide a significant performance boost on devices with powerful GPUs. +3. **Hexagon**: Leverages Qualcomm's Hexagon DSP for faster and more efficient processing. This option is available on devices with Qualcomm Snapdragon processors. +4. **NNAPI**: The Android Neural Networks API (NNAPI) serves as an abstraction layer for running ML models on Android devices.

It's designed to accelerate machine learning tasks, particularly for neural networks, allowing for faster and more efficient execution of your YOLO models. + +By combining quantized YOLO models with the Apple Neural Engine, the Ultralytics iOS App achieves real-time object detection on your iOS device without compromising on accuracy or performance. + +| Release Year | iPhone Name | Chipset Name | Node Size | ANE TOPs | +|--------------|------------------------------------------------------|-------------------------------------------------------|-----------|----------| +| 2017 | [iPhone X](https://en.wikipedia.org/wiki/IPhone_X) | [A11 Bionic](https://en.wikipedia.org/wiki/Apple_A11) | 10 nm | 0.6 | +| 2018 | [iPhone XS](https://en.wikipedia.org/wiki/IPhone_XS) | [A12 Bionic](https://en.wikipedia.org/wiki/Apple_A12) | 7 nm | 5 | +| 2019 | [iPhone 11](https://en.wikipedia.org/wiki/IPhone_11) | [A13 Bionic](https://en.wikipedia.org/wiki/Apple_A13) | 7 nm | 6 | +| 2020 | [iPhone 12](https://en.wikipedia.org/wiki/IPhone_12) | [A14 Bionic](https://en.wikipedia.org/wiki/Apple_A14) | 5 nm | 11 | +| 2021 | [iPhone 13](https://en.wikipedia.org/wiki/IPhone_13) | [A15 Bionic](https://en.wikipedia.org/wiki/Apple_A15) | 5 nm | 15.8 | +| 2022 | [iPhone 14](https://en.wikipedia.org/wiki/IPhone_14) | [A16 Bionic](https://en.wikipedia.org/wiki/Apple_A16) | 4 nm | 17.0 | + +Please note that this list only includes iPhone models from 2017 onwards, and the ANE TOPs values are approximate. + +## Getting Started with the Ultralytics iOS App + +To get started with the Ultralytics iOS App, follow these steps: + +1.

+ +## YOLO: A Brief History + +[YOLO](https://arxiv.org/abs/1506.02640) (You Only Look Once), a popular object detection and image segmentation model, was developed by Joseph Redmon and Ali Farhadi at the University of Washington. Launched in 2015, YOLO quickly gained popularity for its high speed and accuracy. + +- [YOLOv2](https://arxiv.org/abs/1612.08242), released in 2016, improved the original model by incorporating batch normalization, anchor boxes, and dimension clusters. +- [YOLOv3](https://pjreddie.com/media/files/papers/YOLOv3.pdf), launched in 2018, further enhanced the model's performance using a more efficient backbone network, multiple anchors and spatial pyramid pooling. +- [YOLOv4](https://arxiv.org/abs/2004.10934) was released in 2020, introducing innovations like Mosaic data augmentation, a new anchor-free detection head, and a new loss function. +- [YOLOv5](https://github.com/ultralytics/yolov5) further improved the model's performance and added new features such as hyperparameter optimization, integrated experiment tracking and automatic export to popular export formats. +- [YOLOv6](https://github.com/meituan/YOLOv6) was open-sourced by [Meituan](https://about.meituan.com/) in 2022 and is in use in many of the company's autonomous delivery robots. +- [YOLOv7](https://github.com/WongKinYiu/yolov7) added additional tasks such as pose estimation on the COCO keypoints dataset. +- [YOLOv8](https://github.com/ultralytics/ultralytics) is the latest version of YOLO by Ultralytics. As a cutting-edge, state-of-the-art (SOTA) model, YOLOv8 builds on the success of previous versions, introducing new features and improvements for enhanced performance, flexibility, and efficiency. YOLOv8 supports a full range of vision AI tasks, including [detection](tasks/detect.md), [segmentation](tasks/segment.md), [pose estimation](tasks/pose.md), [tracking](modes/track.md), and [classification](tasks/classify.md). This versatility allows users to leverage YOLOv8's capabilities across diverse applications and domains. + +## YOLO Licenses: How is Ultralytics YOLO licensed? + +Ultralytics offers two licensing options to accommodate diverse use cases: + +- **AGPL-3.0 License**: This [OSI-approved](https://opensource.org/licenses/) open-source license is ideal for students and enthusiasts, promoting open collaboration and knowledge sharing.

It includes tools for tracking experiments, packaging code into reproducible runs, and sharing and deploying models. MLflow is designed to work with any machine learning library and programming language. + +## Features + +- **Metrics Logging**: Logs metrics at the end of each epoch and at the end of the training. +- **Parameter Logging**: Logs all the parameters used in the training. +- **Artifacts Logging**: Logs model artifacts, including weights and configuration files, at the end of the training. + +## Setup and Prerequisites + +Ensure MLflow is installed. If not, install it using pip: + +```bash +pip install mlflow +``` + +Make sure that MLflow logging is enabled in Ultralytics settings. Usually, this is controlled by the settings `mflow` key. See the [settings](https://docs.ultralytics.com/quickstart/#ultralytics-settings) page for more info. + +!!! example "Update Ultralytics MLflow Settings" + + === "Python" + Within the Python environment, call the `update` method on the `settings` object to change your settings: + ```python + from ultralytics import settings + + # Update a setting + settings.update({'mlflow': True}) + + # Reset settings to default values + settings.reset() + ``` + + === "CLI" + If you prefer using the command-line interface, the following commands will allow you to modify your settings: + ```bash + # Update a setting + yolo settings runs_dir='/path/to/runs' + + # Reset settings to default values + yolo settings reset + ``` + +## How to Use + +### Commands + +1. **Set a Project Name**: You can set the project name via an environment variable: + ```bash + export MLFLOW_EXPERIMENT_NAME= + ``` + Or use the `project=` argument when training a YOLO model, i.e. `yolo train project=my_project`. + +2. **Set a Run Name**: Similar to setting a project name, you can set the run name via an environment variable: + ```bash + export MLFLOW_RUN= + ``` + Or use the `name=` argument when training a YOLO model, i.e. `yolo train project=my_project name=my_name`. + +3. **Start Local MLflow Server**: To start tracking, use: + ```bash + mlflow server --backend-store-uri runs/mlflow' + ``` + This will start a local server at http://127.0.0.1:5000 by default and save all mlflow logs to the 'runs/mlflow' directory. To specify a different URI, set the `MLFLOW_TRACKING_URI` environment variable. + +4. **Kill MLflow Server Instances**: To stop all running MLflow instances, run: + ```bash + ps aux | grep 'mlflow' | grep -v 'grep' | awk '{print $2}' | xargs kill -9 + ``` + +### Logging + +The logging is taken care of by the `on_pretrain_routine_end`, `on_fit_epoch_end`, and `on_train_end` callback functions. These functions are automatically called during the respective stages of the training process, and they handle the logging of parameters, metrics, and artifacts. + +## Examples + +1. **Logging Custom Metrics**: You can add custom metrics to be logged by modifying the `trainer.metrics` dictionary before `on_fit_epoch_end` is called. + +2. **View Experiment**: To view your logs, navigate to your MLflow server (usually http://127.0.0.1:5000) and select your experiment and run. + YOLO MLflow Experiment + +3. **View Run**: Runs are individual models inside an experiment.

Below is a detailed explanation of each parameter: + +| Parameter | Type | Description | Default Value | +|-----------------|------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------| +| `data` | `str` | The dataset configuration file (in YAML format) to run the tuner on. This file should specify the training and validation data paths, as well as other dataset-specific settings. | | +| `space` | `dict, optional` | A dictionary defining the hyperparameter search space for Ray Tune. Each key corresponds to a hyperparameter name, and the value specifies the range of values to explore during tuning. If not provided, YOLOv8 uses a default search space with various hyperparameters. | | +| `grace_period` | `int, optional` | The grace period in epochs for the [ASHA scheduler](https://docs.ray.io/en/latest/tune/api/schedulers.html) in Ray Tune. The scheduler will not terminate any trial before this number of epochs, allowing the model to have some minimum training before making a decision on early stopping. | 10 | +| `gpu_per_trial` | `int, optional` | The number of GPUs to allocate per trial during tuning. This helps manage GPU usage, particularly in multi-GPU environments. If not provided, the tuner will use all available GPUs. | None | +| `iterations` | `int, optional` | The maximum number of trials to run during tuning. This parameter helps control the total number of hyperparameter combinations tested, ensuring the tuning process does not run indefinitely. | 10 | +| `**train_args` | `dict, optional` | Additional arguments to pass to the `train()` method during tuning. These arguments can include settings like the number of training epochs, batch size, and other training-specific configurations. | {} | + +By customizing these parameters, you can fine-tune the hyperparameter optimization process to suit your specific needs and available computational resources. + +## Default Search Space Description + +The following table lists the default search space parameters for hyperparameter tuning in YOLOv8 with Ray Tune. Each parameter has a specific value range defined by `tune.uniform()`. + +| Parameter | Value Range | Description | +|-------------------|----------------------------|------------------------------------------| +| `lr0` | `tune.uniform(1e-5, 1e-1)` | Initial learning rate | +| `lrf` | `tune.uniform(0.01, 1.0)` | Final learning rate factor | +| `momentum` | `tune.uniform(0.6, 0.98)` | Momentum | +| `weight_decay` | `tune.uniform(0.0, 0.001)` | Weight decay | +| `warmup_epochs` | `tune.uniform(0.0, 5.0)` | Warmup epochs | +| `warmup_momentum` | `tune.uniform(0.0, 0.95)` | Warmup momentum | +| `box` | `tune.uniform(0.02, 0.2)` | Box loss weight | +| `cls` | `tune.uniform(0.2, 4.0)` | Class loss weight | +| `hsv_h` | `tune.uniform(0.0, 0.1)` | Hue augmentation range | +| `hsv_s` | `tune.uniform(0.0, 0.9)` | Saturation augmentation range | +| `hsv_v` | `tune.uniform(0.0, 0.9)` | Value (brightness) augmentation range | +| `degrees` | `tune.uniform(0.0, 45.0)` | Rotation augmentation range (degrees) | +| `translate` | `tune.uniform(0.0, 0.9)` | Translation augmentation range | +| `scale` | `tune.uniform(0.0, 0.9)` | Scaling augmentation range | +| `shear` | `tune.uniform(0.0, 10.0)` | Shear augmentation range (degrees) | +| `perspective` | `tune.uniform(0.0, 0.001)` | Perspective augmentation range | +| `flipud` | `tune.uniform(0.0, 1.0)` | Vertical flip augmentation probability | +| `fliplr` | `tune.uniform(0.0, 1.0)` | Horizontal flip augmentation probability | +| `mosaic` | `tune.uniform(0.0, 1.0)` | Mosaic augmentation probability | +| `mixup` | `tune.uniform(0.0, 1.0)` | Mixup augmentation probability | +| `copy_paste` | `tune.uniform(0.0, 1.0)` | Copy-paste augmentation probability | + +## Custom Search Space Example + +In this example, we demonstrate how to use a custom search space for hyperparameter tuning with Ray Tune and YOLOv8. By providing a custom search space, you can focus the tuning process on specific hyperparameters of interest. + +!!! example "Usage" + + ```python + from ultralytics import YOLO + + # Define a YOLO model + model = YOLO("yolov8n.pt") + + # Run Ray Tune on the model + result_grid = model.tune(data="coco128.yaml", + space={"lr0": tune.uniform(1e-5, 1e-1)}, + epochs=50, + use_ray=True) + ``` + +In the code snippet above, we create a YOLO model with the "yolov8n.pt" pretrained weights. Then, we call the `tune()` method, specifying the dataset configuration with "coco128.yaml". We provide a custom search space for the initial learning rate `lr0` using a dictionary with the key "lr0" and the value `tune.uniform(1e-5, 1e-1)`. Finally, we pass additional training arguments, such as the number of epochs directly to the tune method as `epochs=50`. + +## Processing Ray Tune Results + +After running a hyperparameter tuning experiment with Ray Tune, you might want to perform various analyses on the obtained results. This guide will take you through common workflows for processing and analyzing these results. + +### Loading Tune Experiment Results from a Directory + +After running the tuning experiment with `tuner.fit()`, you can load the results from a directory. This is useful, especially if you're performing the analysis after the initial training script has exited. + +```python +experiment_path = f"{storage_path}/{exp_name}" +print(f"Loading results from {experiment_path}...") + +restored_tuner = tune.Tuner.restore(experiment_path, trainable=train_mnist) +result_grid = restored_tuner.get_results() +``` + +### Basic Experiment-Level Analysis + +Get an overview of how trials performed. You can quickly check if there were any errors during the trials. + +```python +if result_grid.errors: + print("One or more trials failed!") +else: + print("No errors!") +``` + +### Basic Trial-Level Analysis + +Access individual trial hyperparameter configurations and the last reported metrics. + +```python +for i, result in enumerate(result_grid): + print(f"Trial #{i}: Configuration: {result.config}, Last Reported Metrics: {result.metrics}") +``` + +### Plotting the Entire History of Reported Metrics for a Trial + +You can plot the history of reported metrics for each trial to see how the metrics evolved over time. + +```python +import matplotlib.pyplot as plt + +for result in result_grid: + plt.plot(result.metrics_dataframe["training_iteration"], result.metrics_dataframe["mean_accuracy"], label=f"Trial {i}") + +plt.xlabel('Training Iterations') +plt.ylabel('Mean Accuracy') +plt.legend() +plt.show() +``` + +## Summary + +In this documentation, we covered common workflows to analyze the results of experiments run with Ray Tune using Ultralytics. The key steps include loading the experiment results from a directory, performing basic experiment-level and trial-level analysis and plotting metrics. + +Explore further by looking into Ray Tune’s [Analyze Results](https://docs.ray.io/en/latest/tune/examples/tune_analyze_results.html) docs page to get the most out of your hyperparameter tuning experiments. diff --git a/ultralytics/docs/integrations/roboflow.md b/ultralytics/docs/integrations/roboflow.md new file mode 100644 index 0000000000000000000000000000000000000000..ed6b8cd3b65701fd307f44392dfb931bbef62ffe --- /dev/null +++ b/ultralytics/docs/integrations/roboflow.md @@ -0,0 +1,239 @@ +--- +comments: true +description: Learn how to use Roboflow with Ultralytics for labeling and managing images for use in training, and for evaluating model performance. +keywords: Ultralytics, YOLOv8, Roboflow, vector analysis, confusion matrix, data management, image labeling +--- + +# Roboflow + +[Roboflow](https://roboflow.com/?ref=ultralytics) has everything you need to build and deploy computer vision models.

This task is designed to segment any object within an image based on various possible user interaction prompts. FastSAM significantly reduces computational demands while maintaining competitive performance, making it a practical choice for a variety of vision tasks. + +![Fast Segment Anything Model (FastSAM) architecture overview](https://user-images.githubusercontent.com/26833433/248551984-d98f0f6d-7535-45d0-b380-2e1440b52ad7.jpg) + +## Overview + +FastSAM is designed to address the limitations of the [Segment Anything Model (SAM)](sam.md), a heavy Transformer model with substantial computational resource requirements. The FastSAM decouples the segment anything task into two sequential stages: all-instance segmentation and prompt-guided selection. The first stage uses [YOLOv8-seg](../tasks/segment.md) to produce the segmentation masks of all instances in the image. In the second stage, it outputs the region-of-interest corresponding to the prompt. + +## Key Features + +1. **Real-time Solution:** By leveraging the computational efficiency of CNNs, FastSAM provides a real-time solution for the segment anything task, making it valuable for industrial applications that require quick results. + +2. **Efficiency and Performance:** FastSAM offers a significant reduction in computational and resource demands without compromising on performance quality. It achieves comparable performance to SAM but with drastically reduced computational resources, enabling real-time application. + +3. **Prompt-guided Segmentation:** FastSAM can segment any object within an image guided by various possible user interaction prompts, providing flexibility and adaptability in different scenarios. + +4. **Based on YOLOv8-seg:** FastSAM is based on [YOLOv8-seg](../tasks/segment.md), an object detector equipped with an instance segmentation branch. This allows it to effectively produce the segmentation masks of all instances in an image. + +5. **Competitive Results on Benchmarks:** On the object proposal task on MS COCO, FastSAM achieves high scores at a significantly faster speed than [SAM](sam.md) on a single NVIDIA RTX 3090, demonstrating its efficiency and capability. + +6. **Practical Applications:** The proposed approach provides a new, practical solution for a large number of vision tasks at a really high speed, tens or hundreds of times faster than current methods. + +7. **Model Compression Feasibility:** FastSAM demonstrates the feasibility of a path that can significantly reduce the computational effort by introducing an artificial prior to the structure, thus opening new possibilities for large model architecture for general vision tasks. + +## Usage + +### Python API + +The FastSAM models are easy to integrate into your Python applications.

Showcasing the intricate network design of YOLOv4, including the backbone, neck, and head components, and their interconnected layers for optimal real-time object detection. + +## Introduction + +YOLOv4 stands for You Only Look Once version 4. It is a real-time object detection model developed to address the limitations of previous YOLO versions like [YOLOv3](./yolov3.md) and other object detection models. Unlike other convolutional neural network (CNN) based object detectors, YOLOv4 is not only applicable for recommendation systems but also for standalone process management and human input reduction. Its operation on conventional graphics processing units (GPUs) allows for mass usage at an affordable price, and it is designed to work in real-time on a conventional GPU while requiring only one such GPU for training. + +## Architecture + +YOLOv4 makes use of several innovative features that work together to optimize its performance. These include Weighted-Residual-Connections (WRC), Cross-Stage-Partial-connections (CSP), Cross mini-Batch Normalization (CmBN), Self-adversarial-training (SAT), Mish-activation, Mosaic data augmentation, DropBlock regularization, and CIoU loss. These features are combined to achieve state-of-the-art results. + +A typical object detector is composed of several parts including the input, the backbone, the neck, and the head. The backbone of YOLOv4 is pre-trained on ImageNet and is used to predict classes and bounding boxes of objects. The backbone could be from several models including VGG, ResNet, ResNeXt, or DenseNet. The neck part of the detector is used to collect feature maps from different stages and usually includes several bottom-up paths and several top-down paths. The head part is what is used to make the final object detections and classifications. + +## Bag of Freebies + +YOLOv4 also makes use of methods known as "bag of freebies," which are techniques that improve the accuracy of the model during training without increasing the cost of inference. Data augmentation is a common bag of freebies technique used in object detection, which increases the variability of the input images to improve the robustness of the model. Some examples of data augmentation include photometric distortions (adjusting the brightness, contrast, hue, saturation, and noise of an image) and geometric distortions (adding random scaling, cropping, flipping, and rotating). These techniques help the model to generalize better to different types of images. + +## Features and Performance + +YOLOv4 is designed for optimal speed and accuracy in object detection. The architecture of YOLOv4 includes CSPDarknet53 as the backbone, PANet as the neck, and YOLOv3 as the detection head. This design allows YOLOv4 to perform object detection at an impressive speed, making it suitable for real-time applications. YOLOv4 also excels in accuracy, achieving state-of-the-art results in object detection benchmarks. + +## Usage Examples + +As of the time of writing, Ultralytics does not currently support YOLOv4 models. Therefore, any users interested in using YOLOv4 will need to refer directly to the YOLOv4 GitHub repository for installation and usage instructions. + +Here is a brief overview of the typical steps you might take to use YOLOv4: + +1. Visit the YOLOv4 GitHub repository: [https://github.com/AlexeyAB/darknet](https://github.com/AlexeyAB/darknet). + +2. Follow the instructions provided in the README file for installation. This typically involves cloning the repository, installing necessary dependencies, and setting up any necessary environment variables. + +3. Once installation is complete, you can train and use the model as per the usage instructions provided in the repository. This usually involves preparing your dataset, configuring the model parameters, training the model, and then using the trained model to perform object detection. + +Please note that the specific steps may vary depending on your specific use case and the current state of the YOLOv4 repository. Therefore, it is strongly recommended to refer directly to the instructions provided in the YOLOv4 GitHub repository. + +We regret any inconvenience this may cause and will strive to update this document with usage examples for Ultralytics once support for YOLOv4 is implemented. + +## Conclusion + +YOLOv4 is a powerful and efficient object detection model that strikes a balance between speed and accuracy. Its use of unique features and bag of freebies techniques during training allows it to perform excellently in real-time object detection tasks. YOLOv4 can be trained and used by anyone with a conventional GPU, making it accessible and practical for a wide range of applications. + +## Citations and Acknowledgements + +We would like to acknowledge the YOLOv4 authors for their significant contributions in the field of real-time object detection: + +!!! note "" + + === "BibTeX" + + ```bibtex + @misc{bochkovskiy2020yolov4, + title={YOLOv4: Optimal Speed and Accuracy of Object Detection}, + author={Alexey Bochkovskiy and Chien-Yao Wang and Hong-Yuan Mark Liao}, + year={2020}, + eprint={2004.10934}, + archivePrefix={arXiv}, + primaryClass={cs.CV} + } + ``` + +The original YOLOv4 paper can be found on [arXiv](https://arxiv.org/pdf/2004.10934.pdf).

Moreover, YOLOv7 outperforms other object detectors such as YOLOR, YOLOX, Scaled-YOLOv4, YOLOv5, and many others in speed and accuracy. The model is trained on the MS COCO dataset from scratch without using any other datasets or pre-trained weights.

In recent years, real-time object detection development has focused on designing efficient architectures and improving the inference speed of various CPUs, GPUs, and neural processing units (NPUs). YOLOv7 supports both mobile GPU and GPU devices, from the edge to the cloud. + +Unlike traditional real-time object detectors that focus on architecture optimization, YOLOv7 introduces a focus on the optimization of the training process. This includes modules and optimization methods designed to improve the accuracy of object detection without increasing the inference cost, a concept known as the "trainable bag-of-freebies". + +## Key Features + +YOLOv7 introduces several key features: + +1. **Model Re-parameterization**: YOLOv7 proposes a planned re-parameterized model, which is a strategy applicable to layers in different networks with the concept of gradient propagation path. + +2. **Dynamic Label Assignment**: The training of the model with multiple output layers presents a new issue: "How to assign dynamic targets for the outputs of different branches?" To solve this problem, YOLOv7 introduces a new label assignment method called coarse-to-fine lead guided label assignment. + +3. **Extended and Compound Scaling**: YOLOv7 proposes "extend" and "compound scaling" methods for the real-time object detector that can effectively utilize parameters and computation. + +4. **Efficiency**: The method proposed by YOLOv7 can effectively reduce about 40% parameters and 50% computation of state-of-the-art real-time object detector, and has faster inference speed and higher detection accuracy. + +## Usage Examples + +As of the time of writing, Ultralytics does not currently support YOLOv7 models. Therefore, any users interested in using YOLOv7 will need to refer directly to the YOLOv7 GitHub repository for installation and usage instructions. + +Here is a brief overview of the typical steps you might take to use YOLOv7: + +1. Visit the YOLOv7 GitHub repository: [https://github.com/WongKinYiu/yolov7](https://github.com/WongKinYiu/yolov7). + +2. Follow the instructions provided in the README file for installation. This typically involves cloning the repository, installing necessary dependencies, and setting up any necessary environment variables. + +3. Once installation is complete, you can train and use the model as per the usage instructions provided in the repository. This usually involves preparing your dataset, configuring the model parameters, training the model, and then using the trained model to perform object detection. + +Please note that the specific steps may vary depending on your specific use case and the current state of the YOLOv7 repository. Therefore, it is strongly recommended to refer directly to the instructions provided in the YOLOv7 GitHub repository. + +We regret any inconvenience this may cause and will strive to update this document with usage examples for Ultralytics once support for YOLOv7 is implemented. + +## Citations and Acknowledgements + +We would like to acknowledge the YOLOv7 authors for their significant contributions in the field of real-time object detection: + +!!! note "" + + === "BibTeX" + + ```bibtex + @article{wang2022yolov7, + title={{YOLOv7}: Trainable bag-of-freebies sets new state-of-the-art for real-time object detectors}, + author={Wang, Chien-Yao and Bochkovskiy, Alexey and Liao, Hong-Yuan Mark}, + journal={arXiv preprint arXiv:2207.02696}, + year={2022} + } + ``` + +The original YOLOv7 paper can be found on [arXiv](https://arxiv.org/pdf/2207.02696.pdf).

Enable this by setting `stream=True` in the predictor's call method. +- **Batch Processing:** The ability to process multiple images or video frames in a single batch, further speeding up inference time. +- **Integration Friendly:** Easily integrate with existing data pipelines and other software components, thanks to its flexible API. + +Ultralytics YOLO models return either a Python list of `Results` objects, or a memory-efficient Python generator of `Results` objects when `stream=True` is passed to the model during inference: + +!!! example "Predict" + + === "Return a list with `stream=False`" + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('yolov8n.pt') # pretrained YOLOv8n model + + # Run batched inference on a list of images + results = model(['im1.jpg', 'im2.jpg']) # return a list of Results objects + + # Process results list + for result in results: + boxes = result.boxes # Boxes object for bbox outputs + masks = result.masks # Masks object for segmentation masks outputs + keypoints = result.keypoints # Keypoints object for pose outputs + probs = result.probs # Probs object for classification outputs + ``` + + === "Return a generator with `stream=True`" + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('yolov8n.pt') # pretrained YOLOv8n model + + # Run batched inference on a list of images + results = model(['im1.jpg', 'im2.jpg'], stream=True) # return a generator of Results objects + + # Process results generator + for result in results: + boxes = result.boxes # Boxes object for bbox outputs + masks = result.masks # Masks object for segmentation masks outputs + keypoints = result.keypoints # Keypoints object for pose outputs + probs = result.probs # Probs object for classification outputs + ``` + +## Inference Sources + +YOLOv8 can process different types of input sources for inference, as shown in the table below. The sources include static images, video streams, and various data formats. The table also indicates whether each source can be used in streaming mode with the argument `stream=True` ✅. Streaming mode is beneficial for processing videos or live streams as it creates a generator of results instead of loading all frames into memory. + +!!! tip "Tip" + + Use `stream=True` for processing long videos or large datasets to efficiently manage memory. When `stream=False`, the results for all frames or data points are stored in memory, which can quickly add up and cause out-of-memory errors for large inputs. In contrast, `stream=True` utilizes a generator, which only keeps the results of the current frame or data point in memory, significantly reducing memory consumption and preventing out-of-memory issues. + +| Source | Argument | Type | Notes | +|----------------|--------------------------------------------|-----------------|---------------------------------------------------------------------------------------------| +| image | `'image.jpg'` | `str` or `Path` | Single image file. | +| URL | `'https://ultralytics.com/images/bus.jpg'` | `str` | URL to an image. | +| screenshot | `'screen'` | `str` | Capture a screenshot. | +| PIL | `Image.open('im.jpg')` | `PIL.Image` | HWC format with RGB channels. | +| OpenCV | `cv2.imread('im.jpg')` | `np.ndarray` | HWC format with BGR channels `uint8 (0-255)`. | +| numpy | `np.zeros((640,1280,3))` | `np.ndarray` | HWC format with BGR channels `uint8 (0-255)`. | +| torch | `torch.zeros(16,3,320,640)` | `torch.Tensor` | BCHW format with RGB channels `float32 (0.0-1.0)`. | +| CSV | `'sources.csv'` | `str` or `Path` | CSV file containing paths to images, videos, or directories. | +| video ✅ | `'video.mp4'` | `str` or `Path` | Video file in formats like MP4, AVI, etc. | +| directory ✅ | `'path/'` | `str` or `Path` | Path to a directory containing images or videos. | +| glob ✅ | `'path/*.jpg'` | `str` | Glob pattern to match multiple files.

They can be enabled by passing the relevant YAML configuration file such as `tracker=tracker_type.yaml`: + +* [BoT-SORT](https://github.com/NirAharon/BoT-SORT) - Use `botsort.yaml` to enable this tracker. +* [ByteTrack](https://github.com/ifzhang/ByteTrack) - Use `bytetrack.yaml` to enable this tracker. + +The default tracker is BoT-SORT. + +## Tracking + +To run the tracker on video streams, use a trained Detect, Segment or Pose model such as YOLOv8n, YOLOv8n-seg and YOLOv8n-pose. + +!!! example "" + + === "Python" + + ```python + from ultralytics import YOLO + + # Load an official or custom model + model = YOLO('yolov8n.pt') # Load an official Detect model + model = YOLO('yolov8n-seg.pt') # Load an official Segment model + model = YOLO('yolov8n-pose.pt') # Load an official Pose model + model = YOLO('path/to/best.pt') # Load a custom trained model + + # Perform tracking with the model + results = model.track(source="https://youtu.be/LNwODJXcvt4", show=True) # Tracking with default tracker + results = model.track(source="https://youtu.be/LNwODJXcvt4", show=True, tracker="bytetrack.yaml") # Tracking with ByteTrack tracker + ``` + + === "CLI" + + ```bash + # Perform tracking with various models using the command line interface + yolo track model=yolov8n.pt source="https://youtu.be/LNwODJXcvt4" # Official Detect model + yolo track model=yolov8n-seg.pt source="https://youtu.be/LNwODJXcvt4" # Official Segment model + yolo track model=yolov8n-pose.pt source="https://youtu.be/LNwODJXcvt4" # Official Pose model + yolo track model=path/to/best.pt source="https://youtu.be/LNwODJXcvt4" # Custom trained model + + # Track using ByteTrack tracker + yolo track model=path/to/best.pt tracker="bytetrack.yaml" + ``` + +As can be seen in the above usage, tracking is available for all Detect, Segment and Pose models run on videos or streaming sources. + +## Configuration + +### Tracking Arguments + +Tracking configuration shares properties with Predict mode, such as `conf`, `iou`, and `show`. For further configurations, refer to the [Predict](https://docs.ultralytics.com/modes/predict/) model page. + +!!! example "" + + === "Python" + + ```python + from ultralytics import YOLO + + # Configure the tracking parameters and run the tracker + model = YOLO('yolov8n.pt') + results = model.track(source="https://youtu.be/LNwODJXcvt4", conf=0.3, iou=0.5, show=True) + ``` + + === "CLI" + + ```bash + # Configure tracking parameters and run the tracker using the command line interface + yolo track model=yolov8n.pt source="https://youtu.be/LNwODJXcvt4" conf=0.3, iou=0.5 show + ``` + +### Tracker Selection + +Ultralytics also allows you to use a modified tracker configuration file. To do this, simply make a copy of a tracker config file (for example, `custom_tracker.yaml`) from [ultralytics/cfg/trackers](https://github.com/ultralytics/ultralytics/tree/main/ultralytics/cfg/trackers) and modify any configurations (except the `tracker_type`) as per your needs. + +!!! example "" + + === "Python" + + ```python + from ultralytics import YOLO + + # Load the model and run the tracker with a custom configuration file + model = YOLO('yolov8n.pt') + results = model.track(source="https://youtu.be/LNwODJXcvt4", tracker='custom_tracker.yaml') + ``` + + === "CLI" + + ```bash + # Load the model and run the tracker with a custom configuration file using the command line interface + yolo track model=yolov8n.pt source="https://youtu.be/LNwODJXcvt4" tracker='custom_tracker.yaml' + ``` + +For a comprehensive list of tracking arguments, refer to the [ultralytics/cfg/trackers](https://github.com/ultralytics/ultralytics/tree/main/ultralytics/cfg/trackers) page. + +## Python Examples + +### Persisting Tracks Loop + +Here is a Python script using OpenCV (`cv2`) and YOLOv8 to run object tracking on video frames. This script still assumes you have already installed the necessary packages (`opencv-python` and `ultralytics`). The `persist=True` argument tells the tracker that the current image or frame is the next in a sequence and to expect tracks from the previous image in the current image. + +!!! example "Streaming for-loop with tracking" + + ```python + import cv2 + from ultralytics import YOLO + + # Load the YOLOv8 model + model = YOLO('yolov8n.pt') + + # Open the video file + video_path = "path/to/video.mp4" + cap = cv2.VideoCapture(video_path) + + # Loop through the video frames + while cap.isOpened(): + # Read a frame from the video + success, frame = cap.read() + + if success: + # Run YOLOv8 tracking on the frame, persisting tracks between frames + results = model.track(frame, persist=True) + + # Visualize the results on the frame + annotated_frame = results[0].plot() + + # Display the annotated frame + cv2.imshow("YOLOv8 Tracking", annotated_frame) + + # Break the loop if 'q' is pressed + if cv2.waitKey(1) & 0xFF == ord("q"): + break + else: + # Break the loop if the end of the video is reached + break + + # Release the video capture object and close the display window + cap.release() + cv2.destroyAllWindows() + ``` + +Please note the change from `model(frame)` to `model.track(frame)`, which enables object tracking instead of simple detection. This modified script will run the tracker on each frame of the video, visualize the results, and display them in a window. The loop can be exited by pressing 'q'. + +### Plotting Tracks Over Time + +Visualizing object tracks over consecutive frames can provide valuable insights into the movement patterns and behavior of detected objects within a video. With Ultralytics YOLOv8, plotting these tracks is a seamless and efficient process. + +In the following example, we demonstrate how to utilize YOLOv8's tracking capabilities to plot the movement of detected objects across multiple video frames. This script involves opening a video file, reading it frame by frame, and utilizing the YOLO model to identify and track various objects. By retaining the center points of the detected bounding boxes and connecting them, we can draw lines that represent the paths followed by the tracked objects. + +!!! example "Plotting tracks over multiple video frames" + + ```python + from collections import defaultdict + + import cv2 + import numpy as np + + from ultralytics import YOLO + + # Load the YOLOv8 model + model = YOLO('yolov8n.pt') + + # Open the video file + video_path = "path/to/video.mp4" + cap = cv2.VideoCapture(video_path) + + # Store the track history + track_history = defaultdict(lambda: []) + + # Loop through the video frames + while cap.isOpened(): + # Read a frame from the video + success, frame = cap.read() + + if success: + # Run YOLOv8 tracking on the frame, persisting tracks between frames + results = model.track(frame, persist=True) + + # Get the boxes and track IDs + boxes = results[0].boxes.xywh.cpu() + track_ids = results[0].boxes.id.int().cpu().tolist() + + # Visualize the results on the frame + annotated_frame = results[0].plot() + + # Plot the tracks + for box, track_id in zip(boxes, track_ids): + x, y, w, h = box + track = track_history[track_id] + track.append((float(x), float(y))) # x, y center point + if len(track) > 30: # retain 90 tracks for 90 frames + track.pop(0) + + # Draw the tracking lines + points = np.hstack(track).astype(np.int32).reshape((-1, 1, 2)) + cv2.polylines(annotated_frame, [points], isClosed=False, color=(230, 230, 230), thickness=10) + + # Display the annotated frame + cv2.imshow("YOLOv8 Tracking", annotated_frame) + + # Break the loop if 'q' is pressed + if cv2.waitKey(1) & 0xFF == ord("q"): + break + else: + # Break the loop if the end of the video is reached + break + + # Release the video capture object and close the display window + cap.release() + cv2.destroyAllWindows() + ``` + +### Multithreaded Tracking + +Multithreaded tracking provides the capability to run object tracking on multiple video streams simultaneously. This is particularly useful when handling multiple video inputs, such as from multiple surveillance cameras, where concurrent processing can greatly enhance efficiency and performance. + +In the provided Python script, we make use of Python's `threading` module to run multiple instances of the tracker concurrently. Each thread is responsible for running the tracker on one video file, and all the threads run simultaneously in the background. + +To ensure that each thread receives the correct parameters (the video file, the model to use and the file index), we define a function `run_tracker_in_thread` that accepts these parameters and contains the main tracking loop. This function reads the video frame by frame, runs the tracker, and displays the results. + +Two different models are used in this example: `yolov8n.pt` and `yolov8n-seg.pt`, each tracking objects in a different video file. The video files are specified in `video_file1` and `video_file2`. + +The `daemon=True` parameter in `threading.Thread` means that these threads will be closed as soon as the main program finishes. We then start the threads with `start()` and use `join()` to make the main thread wait until both tracker threads have finished. + +Finally, after all threads have completed their task, the windows displaying the results are closed using `cv2.destroyAllWindows()`. + +!!! example "Streaming for-loop with tracking" + + ```python + import threading + import cv2 + from ultralytics import YOLO + + + def run_tracker_in_thread(filename, model, file_index): + """ + Runs a video file or webcam stream concurrently with the YOLOv8 model using threading. + + This function captures video frames from a given file or camera source and utilizes the YOLOv8 model for object + tracking. The function runs in its own thread for concurrent processing. + + Args: + filename (str): The path to the video file or the identifier for the webcam/external camera source. + model (obj): The YOLOv8 model object. + file_index (int): An index to uniquely identify the file being processed, used for display purposes. + + Note: + Press 'q' to quit the video display window. + """ + video = cv2.VideoCapture(filename) # Read the video file + + while True: + ret, frame = video.read() # Read the video frames + + # Exit the loop if no more frames in either video + if not ret: + break + + # Track objects in frames if available + results = model.track(frame, persist=True) + res_plotted = results[0].plot() + cv2.imshow(f"Tracking_Stream_{file_index}", res_plotted) + + key = cv2.waitKey(1) + if key == ord('q'): + break + + # Release video sources + video.release() + + + # Load the models + model1 = YOLO('yolov8n.pt') + model2 = YOLO('yolov8n-seg.pt') + + # Define the video files for the trackers + video_file1 = "path/to/video1.mp4" # Path to video file, 0 for webcam + video_file2 = 0 # Path to video file, 0 for webcam, 1 for external camera + + # Create the tracker threads + tracker_thread1 = threading.Thread(target=run_tracker_in_thread, args=(video_file1, model1, 1), daemon=True) + tracker_thread2 = threading.Thread(target=run_tracker_in_thread, args=(video_file2, model2, 2), daemon=True) + + # Start the tracker threads + tracker_thread1.start() + tracker_thread2.start() + + # Wait for the tracker threads to finish + tracker_thread1.join() + tracker_thread2.join() + + # Clean up and close windows + cv2.destroyAllWindows() + ``` + +This example can easily be extended to handle more video files and models by creating more threads and applying the same methodology. + +## Contribute New Trackers + +Are you proficient in multi-object tracking and have successfully implemented or adapted a tracking algorithm with Ultralytics YOLO?

+ Watch: How to Train a YOLOv8 model on Your Custom Dataset in Google Colab. +

+ +## Why Choose Ultralytics YOLO for Training? + +Here are some compelling reasons to opt for YOLOv8's Train mode: + +- **Efficiency:** Make the most out of your hardware, whether you're on a single-GPU setup or scaling across multiple GPUs. +- **Versatility:** Train on custom datasets in addition to readily available ones like COCO, VOC, and ImageNet. +- **User-Friendly:** Simple yet powerful CLI and Python interfaces for a straightforward training experience. +- **Hyperparameter Flexibility:** A broad range of customizable hyperparameters to fine-tune model performance. + +### Key Features of Train Mode + +The following are some notable features of YOLOv8's Train mode: + +- **Automatic Dataset Download:** Standard datasets like COCO, VOC, and ImageNet are downloaded automatically on first use. +- **Multi-GPU Support:** Scale your training efforts seamlessly across multiple GPUs to expedite the process. +- **Hyperparameter Configuration:** The option to modify hyperparameters through YAML configuration files or CLI arguments. +- **Visualization and Monitoring:** Real-time tracking of training metrics and visualization of the learning process for better insights. + +!!! tip "Tip" + + * YOLOv8 datasets like COCO, VOC, ImageNet and many others automatically download on first use, i.e. `yolo train data=coco.yaml` + +## Usage Examples + +Train YOLOv8n on the COCO128 dataset for 100 epochs at image size 640. The training device can be specified using the `device` argument. If no argument is passed GPU `device=0` will be used if available, otherwise `device=cpu` will be used. See Arguments section below for a full list of training arguments. + +!!! example "Single-GPU and CPU Training Example" + + Device is determined automatically. If a GPU is available then it will be used, otherwise training will start on CPU. + + === "Python" + + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('yolov8n.yaml') # build a new model from YAML + model = YOLO('yolov8n.pt') # load a pretrained model (recommended for training) + model = YOLO('yolov8n.yaml').load('yolov8n.pt') # build from YAML and transfer weights + + # Train the model + results = model.train(data='coco128.yaml', epochs=100, imgsz=640) + ``` + + === "CLI" + + ```bash + # Build a new model from YAML and start training from scratch + yolo detect train data=coco128.yaml model=yolov8n.yaml epochs=100 imgsz=640 + + # Start training from a pretrained *.pt model + yolo detect train data=coco128.yaml model=yolov8n.pt epochs=100 imgsz=640 + + # Build a new model from YAML, transfer pretrained weights to it and start training + yolo detect train data=coco128.yaml model=yolov8n.yaml pretrained=yolov8n.pt epochs=100 imgsz=640 + ``` + +### Multi-GPU Training + +Multi-GPU training allows for more efficient utilization of available hardware resources by distributing the training load across multiple GPUs. This feature is available through both the Python API and the command-line interface. To enable multi-GPU training, specify the GPU device IDs you wish to use. + +!!! example "Multi-GPU Training Example" + + To train with 2 GPUs, CUDA devices 0 and 1 use the following commands. Expand to additional GPUs as required. + + === "Python" + + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('yolov8n.pt') # load a pretrained model (recommended for training) + + # Train the model with 2 GPUs + results = model.train(data='coco128.yaml', epochs=100, imgsz=640, device=[0, 1]) + ``` + + === "CLI" + + ```bash + # Start training from a pretrained *.pt model using GPUs 0 and 1 + yolo detect train data=coco128.yaml model=yolov8n.pt epochs=100 imgsz=640 device=0,1 + ``` + +### Apple M1 and M2 MPS Training + +With the support for Apple M1 and M2 chips integrated in the Ultralytics YOLO models, it's now possible to train your models on devices utilizing the powerful Metal Performance Shaders (MPS) framework. The MPS offers a high-performance way of executing computation and image processing tasks on Apple's custom silicon. + +To enable training on Apple M1 and M2 chips, you should specify 'mps' as your device when initiating the training process. Below is an example of how you could do this in Python and via the command line: + +!!! example "MPS Training Example" + + === "Python" + + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('yolov8n.pt') # load a pretrained model (recommended for training) + + # Train the model with 2 GPUs + results = model.train(data='coco128.yaml', epochs=100, imgsz=640, device='mps') + ``` + + === "CLI" + + ```bash + # Start training from a pretrained *.pt model using GPUs 0 and 1 + yolo detect train data=coco128.yaml model=yolov8n.pt epochs=100 imgsz=640 device=mps + ``` + +While leveraging the computational power of the M1/M2 chips, this enables more efficient processing of the training tasks. For more detailed guidance and advanced configuration options, please refer to the [PyTorch MPS documentation](https://pytorch.org/docs/stable/notes/mps.html). + +### Resuming Interrupted Trainings + +Resuming training from a previously saved state is a crucial feature when working with deep learning models. This can come in handy in various scenarios, like when the training process has been unexpectedly interrupted, or when you wish to continue training a model with new data or for more epochs. + +When training is resumed, Ultralytics YOLO loads the weights from the last saved model and also restores the optimizer state, learning rate scheduler, and the epoch number. This allows you to continue the training process seamlessly from where it was left off. + +You can easily resume training in Ultralytics YOLO by setting the `resume` argument to `True` when calling the `train` method, and specifying the path to the `.pt` file containing the partially trained model weights. + +Below is an example of how to resume an interrupted training using Python and via the command line: + +!!! example "Resume Training Example" + + === "Python" + + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('path/to/last.pt') # load a partially trained model + + # Resume training + results = model.train(resume=True) + ``` + + === "CLI" + + ```bash + # Resume an interrupted training + yolo train resume model=path/to/last.pt + ``` + +By setting `resume=True`, the `train` function will continue training from where it left off, using the state stored in the 'path/to/last.pt' file. If the `resume` argument is omitted or set to `False`, the `train` function will start a new training session. + +Remember that checkpoints are saved at the end of every epoch by default, or at fixed interval using the `save_period` argument, so you must complete at least 1 epoch to resume a training run. + +## Arguments + +Training settings for YOLO models refer to the various hyperparameters and configurations used to train the model on a dataset. These settings can affect the model's performance, speed, and accuracy. Some common YOLO training settings include the batch size, learning rate, momentum, and weight decay. Other factors that may affect the training process include the choice of optimizer, the choice of loss function, and the size and composition of the training dataset. It is important to carefully tune and experiment with these settings to achieve the best possible performance for a given task. + +| Key | Value | Description | +|-------------------|----------|------------------------------------------------------------------------------------------------| +| `model` | `None` | path to model file, i.e. yolov8n.pt, yolov8n.yaml | +| `data` | `None` | path to data file, i.e. coco128.yaml | +| `epochs` | `100` | number of epochs to train for | +| `patience` | `50` | epochs to wait for no observable improvement for early stopping of training | +| `batch` | `16` | number of images per batch (-1 for AutoBatch) | +| `imgsz` | `640` | size of input images as integer | +| `save` | `True` | save train checkpoints and predict results | +| `save_period` | `-1` | Save checkpoint every x epochs (disabled if < 1) | +| `cache` | `False` | True/ram, disk or False.

This guide serves as a complete resource for understanding how to effectively use the Val mode to ensure that your models are both accurate and reliable. + +## Why Validate with Ultralytics YOLO? + +Here's why using YOLOv8's Val mode is advantageous: + +- **Precision:** Get accurate metrics like mAP50, mAP75, and mAP50-95 to comprehensively evaluate your model. +- **Convenience:** Utilize built-in features that remember training settings, simplifying the validation process. +- **Flexibility:** Validate your model with the same or different datasets and image sizes. +- **Hyperparameter Tuning:** Use validation metrics to fine-tune your model for better performance. + +### Key Features of Val Mode + +These are the notable functionalities offered by YOLOv8's Val mode: + +- **Automated Settings:** Models remember their training configurations for straightforward validation. +- **Multi-Metric Support:** Evaluate your model based on a range of accuracy metrics. +- **CLI and Python API:** Choose from command-line interface or Python API based on your preference for validation. +- **Data Compatibility:** Works seamlessly with datasets used during the training phase as well as custom datasets. + +!!! tip "Tip" + + * YOLOv8 models automatically remember their training settings, so you can validate a model at the same image size and on the original dataset easily with just `yolo val model=yolov8n.pt` or `model('yolov8n.pt').val()` + +## Usage Examples + +Validate trained YOLOv8n model accuracy on the COCO128 dataset. No argument need to passed as the `model` retains it's training `data` and arguments as model attributes. See Arguments section below for a full list of export arguments. + +!!! example "" + + === "Python" + + ```python + from ultralytics import YOLO + + # Load a model + model = YOLO('yolov8n.pt') # load an official model + model = YOLO('path/to/best.pt') # load a custom model + + # Validate the model + metrics = model.val() # no arguments needed, dataset and settings remembered + metrics.box.map # map50-95 + metrics.box.map50 # map50 + metrics.box.map75 # map75 + metrics.box.maps # a list contains map50-95 of each category + ``` + === "CLI" + + ```bash + yolo detect val model=yolov8n.pt # val official model + yolo detect val model=path/to/best.pt # val custom model + ``` + +## Arguments + +Validation settings for YOLO models refer to the various hyperparameters and configurations used to evaluate the model's performance on a validation dataset. These settings can affect the model's performance, speed, and accuracy. Some common YOLO validation settings include the batch size, the frequency with which validation is performed during training, and the metrics used to evaluate the model's performance. Other factors that may affect the validation process include the size and composition of the validation dataset and the specific task the model is being used for. It is important to carefully tune and experiment with these settings to ensure that the model is performing well on the validation dataset and to detect and prevent overfitting. + +| Key | Value | Description | +|---------------|---------|--------------------------------------------------------------------| +| `data` | `None` | path to data file, i.e. coco128.yaml | +| `imgsz` | `640` | size of input images as integer | +| `batch` | `16` | number of images per batch (-1 for AutoBatch) | +| `save_json` | `False` | save results to JSON file | +| `save_hybrid` | `False` | save hybrid version of labels (labels + additional predictions) | +| `conf` | `0.001` | object confidence threshold for detection | +| `iou` | `0.6` | intersection over union (IoU) threshold for NMS | +| `max_det` | `300` | maximum number of detections per image | +| `half` | `True` | use half precision (FP16) | +| `device` | `None` | device to run on, i.e. cuda device=0/1/2/3 or device=cpu | +| `dnn` | `False` | use OpenCV DNN for ONNX inference | +| `plots` | `False` | show plots during training | +| `rect` | `False` | rectangular val with each batch collated for minimum padding | +| `split` | `val` | dataset split to use for validation, i.e. 'val', 'test' or 'train' | +| diff --git a/ultralytics/docs/overrides/partials/comments.html b/ultralytics/docs/overrides/partials/comments.html new file mode 100644 index 0000000000000000000000000000000000000000..dcee5a9f14e1b0f2c386fee3a7fbf8a0addb6a82 --- /dev/null +++ b/ultralytics/docs/overrides/partials/comments.html @@ -0,0 +1,50 @@ +{% if page.meta.comments %} +

Understand the model structure, data augmentation methods, training strategies, and loss computation techniques. +keywords: Ultralytics, YOLOv5, Object Detection, Architecture, Model Structure, Data Augmentation, Training Strategies, Loss Computation +--- + +# Ultralytics YOLOv5 Architecture + +YOLOv5 (v6.0/6.1) is a powerful object detection algorithm developed by Ultralytics. This article dives deep into the YOLOv5 architecture, data augmentation strategies, training methodologies, and loss computation techniques. This comprehensive understanding will help improve your practical application of object detection in various fields, including surveillance, autonomous vehicles, and image recognition. + +## 1. Model Structure + +YOLOv5's architecture consists of three main parts: + +- **Backbone**: This is the main body of the network. For YOLOv5, the backbone is designed using the `New CSP-Darknet53` structure, a modification of the Darknet architecture used in previous versions. +- **Neck**: This part connects the backbone and the head. In YOLOv5, `SPPF` and `New CSP-PAN` structures are utilized. +- **Head**: This part is responsible for generating the final output. YOLOv5 uses the `YOLOv3 Head` for this purpose. + +The structure of the model is depicted in the image below. The model structure details can be found in `yolov5l.yaml`. + +![yolov5](https://user-images.githubusercontent.com/31005897/172404576-c260dcf9-76bb-4bc8-b6a9-f2d987792583.png) + +YOLOv5 introduces some minor changes compared to its predecessors: + +1. The `Focus` structure, found in earlier versions, is replaced with a `6x6 Conv2d` structure. This change boosts efficiency [#4825](https://github.com/ultralytics/yolov5/issues/4825). +2. The `SPP` structure is replaced with `SPPF`. This alteration more than doubles the speed of processing. + +To test the speed of `SPP` and `SPPF`, the following code can be used: + +

+ +## 2. Data Augmentation Techniques + +YOLOv5 employs various data augmentation techniques to improve the model's ability to generalize and reduce overfitting. These techniques include: + +- **Mosaic Augmentation**: An image processing technique that combines four training images into one in ways that encourage object detection models to better handle various object scales and translations. + + ![mosaic](https://user-images.githubusercontent.com/31005897/159109235-c7aad8f2-1d4f-41f9-8d5f-b2fde6f2885e.png) + +- **Copy-Paste Augmentation**: An innovative data augmentation method that copies random patches from an image and pastes them onto another randomly chosen image, effectively generating a new training sample. + + ![copy-paste](https://user-images.githubusercontent.com/31005897/159116277-91b45033-6bec-4f82-afc4-41138866628e.png) + +- **Random Affine Transformations**: This includes random rotation, scaling, translation, and shearing of the images. + + ![random-affine](https://user-images.githubusercontent.com/31005897/159109326-45cd5acb-14fa-43e7-9235-0f21b0021c7d.png) + +- **MixUp Augmentation**: A method that creates composite images by taking a linear combination of two images and their associated labels. + + ![mixup](https://user-images.githubusercontent.com/31005897/159109361-3b24333b-f481-478b-ae00-df7838f0b5cd.png) + +- **Albumentations**: A powerful library for image augmenting that supports a wide variety of augmentation techniques. +- **HSV Augmentation**: Random changes to the Hue, Saturation, and Value of the images. + + ![hsv](https://user-images.githubusercontent.com/31005897/159109407-83d100ba-1aba-4f4b-aa03-4f048f815981.png) + +- **Random Horizontal Flip**: An augmentation method that randomly flips images horizontally. + + ![horizontal-flip](https://user-images.githubusercontent.com/31005897/159109429-0d44619a-a76a-49eb-bfc0-6709860c043e.png) + +## 3. Training Strategies + +YOLOv5 applies several sophisticated training strategies to enhance the model's performance. They include: + +- **Multiscale Training**: The input images are randomly rescaled within a range of 0.5 to 1.5 times their original size during the training process. +- **AutoAnchor**: This strategy optimizes the prior anchor boxes to match the statistical characteristics of the ground truth boxes in your custom data. +- **Warmup and Cosine LR Scheduler**: A method to adjust the learning rate to enhance model performance. +- **Exponential Moving Average (EMA)**: A strategy that uses the average of parameters over past steps to stabilize the training process and reduce generalization error. +- **Mixed Precision Training**: A method to perform operations in half-precision format, reducing memory usage and enhancing computational speed. +- **Hyperparameter Evolution**: A strategy to automatically tune hyperparameters to achieve optimal performance. + +## 4. Additional Features + +### 4.1 Compute Losses + +The loss in YOLOv5 is computed as a combination of three individual loss components: + +- **Classes Loss (BCE Loss)**: Binary Cross-Entropy loss, measures the error for the classification task. +- **Objectness Loss (BCE Loss)**: Another Binary Cross-Entropy loss, calculates the error in detecting whether an object is present in a particular grid cell or not. +- **Location Loss (CIoU Loss)**: Complete IoU loss, measures the error in localizing the object within the grid cell. + +The overall loss function is depicted by: + +![loss](https://latex.codecogs.com/svg.image?Loss=\lambda_1L_{cls}+\lambda_2L_{obj}+\lambda_3L_{loc}) + +### 4.2 Balance Losses + +The objectness losses of the three prediction layers (`P3`, `P4`, `P5`) are weighted differently. The balance weights are `[4.0, 1.0, 0.4]` respectively. This approach ensures that the predictions at different scales contribute appropriately to the total loss. + +![obj_loss](https://latex.codecogs.com/svg.image?L_{obj}=4.0\cdot&space;L_{obj}^{small}+1.0\cdot&space;L_{obj}^{medium}+0.4\cdot&space;L_{obj}^{large}) + +### 4.3 Eliminate Grid Sensitivity + +The YOLOv5 architecture makes some important changes to the box prediction strategy compared to earlier versions of YOLO. In YOLOv2 and YOLOv3, the box coordinates were directly predicted using the activation of the last layer. + +![b_x](https://latex.codecogs.com/svg.image?b_x=\sigma(t_x)+c_x) +![b_y](https://latex.codecogs.com/svg.image?b_y=\sigma(t_y)+c_y) +![b_w](https://latex.codecogs.com/svg.image?b_w=p_w\cdot&space;e^{t_w}) +![b_h](https://latex.codecogs.com/svg.image?b_h=p_h\cdot&space;e^{t_h}) + + + +However, in YOLOv5, the formula for predicting the box coordinates has been updated to reduce grid sensitivity and prevent the model from predicting unbounded box dimensions. + +The revised formulas for calculating the predicted bounding box are as follows: + +![bx](https://latex.codecogs.com/svg.image?b_x=(2\cdot\sigma(t_x)-0.5)+c_x) +![by](https://latex.codecogs.com/svg.image?b_y=(2\cdot\sigma(t_y)-0.5)+c_y) +![bw](https://latex.codecogs.com/svg.image?b_w=p_w\cdot(2\cdot\sigma(t_w))^2) +![bh](https://latex.codecogs.com/svg.image?b_h=p_h\cdot(2\cdot\sigma(t_h))^2) + +Compare the center point offset before and after scaling. The center point offset range is adjusted from (0, 1) to (-0.5, 1.5). Therefore, offset can easily get 0 or 1. + + + +Compare the height and width scaling ratio(relative to anchor) before and after adjustment. The original yolo/darknet box equations have a serious flaw. Width and Height are completely unbounded as they are simply out=exp(in), which is dangerous, as it can lead to runaway gradients, instabilities, NaN losses and ultimately a complete loss of training. [refer this issue](https://github.com/ultralytics/yolov5/issues/471#issuecomment-662009779) + + + +### 4.4 Build Targets + +The build target process in YOLOv5 is critical for training efficiency and model accuracy. It involves assigning ground truth boxes to the appropriate grid cells in the output map and matching them with the appropriate anchor boxes. + +This process follows these steps: + +- Calculate the ratio of the ground truth box dimensions and the dimensions of each anchor template. + +![rw](https://latex.codecogs.com/svg.image?r_w=w_{gt}/w_{at}) + +![rh](https://latex.codecogs.com/svg.image?r_h=h_{gt}/h_{at}) + +![rwmax](https://latex.codecogs.com/svg.image?r_w^{max}=max(r_w,1/r_w)) + +![rhmax](https://latex.codecogs.com/svg.image?r_h^{max}=max(r_h,1/r_h)) + +![rmax](https://latex.codecogs.com/svg.image?r^{max}=max(r_w^{max},r_h^{max})) + +![match](https://latex.codecogs.com/svg.image?r^{max}<{\rm&space;anchor_t}) + + + +- If the calculated ratio is within the threshold, match the ground truth box with the corresponding anchor. + + + +- Assign the matched anchor to the appropriate cells, keeping in mind that due to the revised center point offset, a ground truth box can be assigned to more than one anchor. Because the center point offset range is adjusted from (0, 1) to (-0.5, 1.5). GT Box can be assigned to more anchors. + + + +This way, the build targets process ensures that each ground truth object is properly assigned and matched during the training process, allowing YOLOv5 to learn the task of object detection more effectively. + +## Conclusion + +In conclusion, YOLOv5 represents a significant step forward in the development of real-time object detection models. By incorporating various new features, enhancements, and training strategies, it surpasses previous versions of the YOLO family in performance and efficiency. + +The primary enhancements in YOLOv5 include the use of a dynamic architecture, an extensive range of data augmentation techniques, innovative training strategies, as well as important adjustments in computing losses and the process of building targets. All these innovations significantly improve the accuracy and efficiency of object detection while retaining a high degree of speed, which is the trademark of YOLO models. diff --git a/ultralytics/docs/yolov5/tutorials/clearml_logging_integration.md b/ultralytics/docs/yolov5/tutorials/clearml_logging_integration.md new file mode 100644 index 0000000000000000000000000000000000000000..43c8395c4318f31d5764396b577269fed6166971 --- /dev/null +++ b/ultralytics/docs/yolov5/tutorials/clearml_logging_integration.md @@ -0,0 +1,240 @@ +--- +comments: true +description: Learn how ClearML can enhance your YOLOv5 pipeline – track your training runs, version your data, remotely monitor your models and optimize performance. +keywords: ClearML, YOLOv5, Ultralytics, AI toolbox, training data, remote training, hyperparameter optimization, YOLOv5 model +--- + +# ClearML Integration + +Clear|MLClear|ML + +## About ClearML + +[ClearML](https://cutt.ly/yolov5-tutorial-clearml) is an [open-source](https://github.com/allegroai/clearml) toolbox designed to save you time ⏱️. + +🔨 Track every YOLOv5 training run in the experiment manager + +🔧 Version and easily access your custom training data with the integrated ClearML Data Versioning Tool + +🔦 Remotely train and monitor your YOLOv5 training runs using ClearML Agent + +🔬 Get the very best mAP using ClearML Hyperparameter Optimization + +🔭 Turn your newly trained YOLOv5 model into an API with just a few commands using ClearML Serving + +

+
+ +## 🦾 Setting Things Up + +To keep track of your experiments and/or data, ClearML needs to communicate to a server. You have 2 options to get one: + +Either sign up for free to the [ClearML Hosted Service](https://cutt.ly/yolov5-tutorial-clearml) or you can set up your own server, see [here](https://clear.ml/docs/latest/docs/deploying_clearml/clearml_server). Even the server is open-source, so even if you're dealing with sensitive data, you should be good to go! + +1. Install the `clearml` python package: + + ```bash + pip install clearml + ``` + +2. Connect the ClearML SDK to the server by [creating credentials](https://app.clear.ml/settings/workspace-configuration) (go right top to Settings -> Workspace -> Create new credentials), then execute the command below and follow the instructions: + + ```bash + clearml-init + ``` + +That's it! You're done 😎 + +
+ +## 🚀 Training YOLOv5 With ClearML + +To enable ClearML experiment tracking, simply install the ClearML pip package. + +```bash +pip install clearml>=1.2.0 +``` + +This will enable integration with the YOLOv5 training script. Every training run from now on, will be captured and stored by the ClearML experiment manager. + +If you want to change the `project_name` or `task_name`, use the `--project` and `--name` arguments of the `train.py` script, by default the project will be called `YOLOv5` and the task `Training`. PLEASE NOTE: ClearML uses `/` as a delimiter for subprojects, so be careful when using `/` in your project name! + +```bash +python train.py --img 640 --batch 16 --epochs 3 --data coco128.yaml --weights yolov5s.pt --cache +``` + +or with custom project and task name: + +```bash +python train.py --project my_project --name my_training --img 640 --batch 16 --epochs 3 --data coco128.yaml --weights yolov5s.pt --cache +``` + +This will capture: + +- Source code + uncommitted changes +- Installed packages +- (Hyper)parameters +- Model files (use `--save-period n` to save a checkpoint every n epochs) +- Console output +- Scalars (mAP_0.5, mAP_0.5:0.95, precision, recall, losses, learning rates, ...) +- General info such as machine details, runtime, creation date etc. +- All produced plots such as label correlogram and confusion matrix +- Images with bounding boxes per epoch +- Mosaic per epoch +- Validation images per epoch +- ... + +That's a lot right? 🤯 Now, we can visualize all of this information in the ClearML UI to get an overview of our training progress. Add custom columns to the table view (such as e.g. mAP_0.5) so you can easily sort on the best performing model. Or select multiple experiments and directly compare them! + +There even more we can do with all of this information, like hyperparameter optimization and remote execution, so keep reading if you want to see how that works! + +
+ +## 🔗 Dataset Version Management + +Versioning your data separately from your code is generally a good idea and makes it easy to acquire the latest version too. This repository supports supplying a dataset version ID, and it will make sure to get the data if it's not there yet. Next to that, this workflow also saves the used dataset ID as part of the task parameters, so you will always know for sure which data was used in which experiment! + +![ClearML Dataset Interface](https://github.com/thepycoder/clearml_screenshots/raw/main/clearml_data.gif) + +### Prepare Your Dataset + +The YOLOv5 repository supports a number of different datasets by using YAML files containing their information. By default datasets are downloaded to the `../datasets` folder in relation to the repository root folder. So if you downloaded the `coco128` dataset using the link in the YAML or with the scripts provided by yolov5, you get this folder structure: + +``` +.. +|_ yolov5 +|_ datasets + |_ coco128 + |_ images + |_ labels + |_ LICENSE + |_ README.txt +``` + +But this can be any dataset you wish. Feel free to use your own, as long as you keep to this folder structure. + +Next, ⚠️**copy the corresponding YAML file to the root of the dataset folder**⚠️. This YAML files contains the information ClearML will need to properly use the dataset. You can make this yourself too, of course, just follow the structure of the example YAMLs. + +Basically we need the following keys: `path`, `train`, `test`, `val`, `nc`, `names`. + +``` +.. +|_ yolov5 +|_ datasets + |_ coco128 + |_ images + |_ labels + |_ coco128.yaml # <---- HERE! + |_ LICENSE + |_ README.txt +``` + +### Upload Your Dataset + +To get this dataset into ClearML as a versioned dataset, go to the dataset root folder and run the following command: + +```bash +cd coco128 +clearml-data sync --project YOLOv5 --name coco128 --folder . +``` + +The command `clearml-data sync` is actually a shorthand command. You could also run these commands one after the other: + +```bash +# Optionally add --parent if you want to base +# this version on another dataset version, so no duplicate files are uploaded! +clearml-data create --name coco128 --project YOLOv5 +clearml-data add --files . +clearml-data close +``` + +### Run Training Using A ClearML Dataset + +Now that you have a ClearML dataset, you can very simply use it to train custom YOLOv5 🚀 models! + +```bash +python train.py --img 640 --batch 16 --epochs 3 --data clearml:// --weights yolov5s.pt --cache +``` + +
+ +## 👀 Hyperparameter Optimization + +Now that we have our experiments and data versioned, it's time to take a look at what we can build on top! + +Using the code information, installed packages and environment details, the experiment itself is now **completely reproducible**. In fact, ClearML allows you to clone an experiment and even change its parameters. We can then just rerun it with these new parameters automatically, this is basically what HPO does! + +To **run hyperparameter optimization locally**, we've included a pre-made script for you. Just make sure a training task has been run at least once, so it is in the ClearML experiment manager, we will essentially clone it and change its hyperparameters. + +You'll need to fill in the ID of this `template task` in the script found at `utils/loggers/clearml/hpo.py` and then just run it :) You can change `task.execute_locally()` to `task.execute()` to put it in a ClearML queue and have a remote agent work on it instead. + +```bash +# To use optuna, install it first, otherwise you can change the optimizer to just be RandomSearch +pip install optuna +python utils/loggers/clearml/hpo.py +``` + +![HPO](https://github.com/thepycoder/clearml_screenshots/raw/main/hpo.png) + +## 🤯 Remote Execution (advanced) + +Running HPO locally is really handy, but what if we want to run our experiments on a remote machine instead? Maybe you have access to a very powerful GPU machine on-site, or you have some budget to use cloud GPUs. This is where the ClearML Agent comes into play. Check out what the agent can do here: + +- [YouTube video](https://youtu.be/MX3BrXnaULs) +- [Documentation](https://clear.ml/docs/latest/docs/clearml_agent) + +In short: every experiment tracked by the experiment manager contains enough information to reproduce it on a different machine (installed packages, uncommitted changes etc.). So a ClearML agent does just that: it listens to a queue for incoming tasks and when it finds one, it recreates the environment and runs it while still reporting scalars, plots etc. to the experiment manager. + +You can turn any machine (a cloud VM, a local GPU machine, your own laptop ... ) into a ClearML agent by simply running: + +```bash +clearml-agent daemon --queue [--docker] +``` + +### Cloning, Editing And Enqueuing + +With our agent running, we can give it some work.

This tool will automatically spin up new remote machines in the cloud of your choice (AWS, GCP, Azure) and turn them into ClearML agents for you whenever there are experiments detected in the queue.

Define Fitness + +Fitness is the value we seek to maximize. In YOLOv5 we define a default fitness function as a weighted combination of metrics: `mAP@0.5` contributes 10% of the weight and `mAP@0.5:0.95` contributes the remaining 90%, with [Precision `P` and Recall `R`](https://en.wikipedia.org/wiki/Precision_and_recall) absent.

UPDATED 25 September 2022. + +From [https://en.wikipedia.org/wiki/Ensemble_learning](https://en.wikipedia.org/wiki/Ensemble_learning): +> Ensemble modeling is a process where multiple diverse models are created to predict an outcome, either by using many different modeling algorithms or using different training data sets. The ensemble model then aggregates the prediction of each base model and results in once final prediction for the unseen data. The motivation for using ensemble models is to reduce the generalization error of the prediction. As long as the base models are diverse and independent, the prediction error of the model decreases when the ensemble approach is used. The approach seeks the wisdom of crowds in making a prediction. Even though the ensemble model has multiple base models within the model, it acts and performs as a single model. + +## Before You Start + +Clone repo and install [requirements.txt](https://github.com/ultralytics/yolov5/blob/master/requirements.txt) in a [**Python>=3.8.0**](https://www.python.org/) environment, including [**PyTorch>=1.8**](https://pytorch.org/get-started/locally/).

Here we select [YOLOv5s](https://github.com/ultralytics/yolov5/blob/master/models/yolov5s.yaml), the smallest and fastest model available. See our README [table](https://github.com/ultralytics/yolov5#pretrained-checkpoints) for a full comparison of all models. We will train this model with Multi-GPU on the [COCO](https://github.com/ultralytics/yolov5/blob/master/data/scripts/get_coco.sh) dataset. + +

YOLOv5 Models

+ +### Single GPU + +```bash +python train.py --batch 64 --data coco.yaml --weights yolov5s.pt --device 0 +``` + +### Multi-GPU [DataParallel](https://pytorch.org/docs/stable/nn.html#torch.nn.DataParallel) Mode (⚠️ not recommended) + +You can increase the `device` to use Multiple GPUs in DataParallel mode. + +```bash +python train.py --batch 64 --data coco.yaml --weights yolov5s.pt --device 0,1 +``` + +This method is slow and barely speeds up training compared to using just 1 GPU. + +### Multi-GPU [DistributedDataParallel](https://pytorch.org/docs/stable/nn.html#torch.nn.parallel.DistributedDataParallel) Mode (✅ recommended) + +You will have to pass `python -m torch.distributed.run --nproc_per_node`, followed by the usual arguments. + +```bash +python -m torch.distributed.run --nproc_per_node 2 train.py --batch 64 --data coco.yaml --weights yolov5s.pt --device 0,1 +``` + +`--nproc_per_node` specifies how many GPUs you would like to use. In the example above, it is 2. +`--batch ` is the total batch-size. It will be divided evenly to each GPU. In the example above, it is 64/2=32 per GPU. + +The code above will use GPUs `0... (N-1)`. + +
+ Use specific GPUs (click to expand) + +You can do so by simply passing `--device` followed by your specific GPUs. For example, in the code below, we will use GPUs `2,3`. + +```bash +python -m torch.distributed.run --nproc_per_node 2 train.py --batch 64 --data coco.yaml --cfg yolov5s.yaml --weights '' --device 2,3 +``` + +
+ +
+ Use SyncBatchNorm (click to expand) + +[SyncBatchNorm](https://pytorch.org/docs/master/generated/torch.nn.SyncBatchNorm.html) could increase accuracy for multiple gpu training, however, it will slow down training by a significant factor. It is **only** available for Multiple GPU DistributedDataParallel training. + +It is best used when the batch-size on **each** GPU is small (<= 8). + +To use SyncBatchNorm, simple pass `--sync-bn` to the command like below, + +```bash +python -m torch.distributed.run --nproc_per_node 2 train.py --batch 64 --data coco.yaml --cfg yolov5s.yaml --weights '' --sync-bn +``` + +
+ +
+ Use Multiple machines (click to expand) + +This is **only** available for Multiple GPU DistributedDataParallel training. + +Before we continue, make sure the files on all machines are the same, dataset, codebase, etc. Afterwards, make sure the machines can communicate to each other. + +You will have to choose a master machine(the machine that the others will talk to). Note down its address(`master_addr`) and choose a port(`master_port`). I will use `master_addr = 192.168.1.1` and `master_port = 1234` for the example below. + +To use it, you can do as the following, + +```bash +# On master machine 0 +python -m torch.distributed.run --nproc_per_node G --nnodes N --node_rank 0 --master_addr "192.168.1.1" --master_port 1234 train.py --batch 64 --data coco.yaml --cfg yolov5s.yaml --weights '' +``` + +```bash +# On machine R +python -m torch.distributed.run --nproc_per_node G --nnodes N --node_rank R --master_addr "192.168.1.1" --master_port 1234 train.py --batch 64 --data coco.yaml --cfg yolov5s.yaml --weights '' +``` + +where `G` is number of GPU per machine, `N` is the number of machines, and `R` is the machine number from `0...(N-1)`. Let's say I have two machines with two GPUs each, it would be `G = 2` , `N = 2`, and `R = 1` for the above. + +Training will not start until all `N` machines are connected. Output will only be shown on master machine! + +
+ +### Notes + +- Windows support is untested, Linux is recommended. +- `--batch ` must be a multiple of the number of GPUs. +- GPU 0 will take slightly more memory than the other GPUs as it maintains EMA and is responsible for checkpointing etc. +- If you get `RuntimeError: Address already in use`, it could be because you are running multiple trainings at a time. To fix this, simply use a different port number by adding `--master_port` like below, + +```bash +python -m torch.distributed.run --master_port 1234 --nproc_per_node 2 ... +``` + +## Results + +DDP profiling results on an [AWS EC2 P4d instance](https://docs.ultralytics.com/yolov5/environments/aws_quickstart_tutorial/) with 8x A100 SXM4-40GB for YOLOv5l for 1 COCO epoch. + +

DeepSparse is sparsity-aware, meaning it skips the zeroed out parameters, shrinking amount of compute in a forward pass. Since the sparse computation is now memory bound, DeepSparse executes the network depth-wise, breaking the problem into Tensor Columns, vertical stripes of computation that fit in cache. + +

The input layer will remain initialized by random weights. + +### Number of Classes + +To load a pretrained YOLOv5s model with 10 output classes rather than the default 80: + +```python +model = torch.hub.load('ultralytics/yolov5', 'yolov5s', classes=10) +``` + +In this case the model will be composed of pretrained weights **except for** the output layers, which are no longer the same shape as the pretrained output layers. The output layers will remain initialized by random weights. + +### Force Reload + +If you run into problems with the above steps, setting `force_reload=True` may help by discarding the existing cache and force a fresh download of the latest YOLOv5 version from PyTorch Hub. + +```python +model = torch.hub.load('ultralytics/yolov5', 'yolov5s', force_reload=True) # force reload +``` + +### Screenshot Inference + +To run inference on your desktop screen: + +```python +import torch +from PIL import ImageGrab + +# Model +model = torch.hub.load('ultralytics/yolov5', 'yolov5s') + +# Image +im = ImageGrab.grab() # take a screenshot + +# Inference +results = model(im) +``` + +### Multi-GPU Inference + +YOLOv5 models can be loaded to multiple GPUs in parallel with threaded inference: + +```python +import torch +import threading + +def run(model, im): + results = model(im) + results.save() + +# Models +model0 = torch.hub.load('ultralytics/yolov5', 'yolov5s', device=0) +model1 = torch.hub.load('ultralytics/yolov5', 'yolov5s', device=1) + +# Inference +threading.Thread(target=run, args=[model0, 'https://ultralytics.com/images/zidane.jpg'], daemon=True).start() +threading.Thread(target=run, args=[model1, 'https://ultralytics.com/images/bus.jpg'], daemon=True).start() +``` + +### Training + +To load a YOLOv5 model for training rather than inference, set `autoshape=False`. To load a model with randomly initialized weights (to train from scratch) use `pretrained=False`. You must provide your own training script in this case. Alternatively see our YOLOv5 [Train Custom Data Tutorial](https://docs.ultralytics.com/yolov5/tutorials/train_custom_data) for model training. + +```python +model = torch.hub.load('ultralytics/yolov5', 'yolov5s', autoshape=False) # load pretrained +model = torch.hub.load('ultralytics/yolov5', 'yolov5s', autoshape=False, pretrained=False) # load scratch +``` + +### Base64 Results + +For use with API services.

UPDATED 25 May 2022. + +Most of the time good results can be obtained with no changes to the models or training settings, **provided your dataset is sufficiently large and well labelled**. If at first you don't get good results, there are steps you might be able to take to improve, but we always recommend users **first train with all default settings** before considering any changes. This helps establish a performance baseline and spot areas for improvement. + +If you have questions about your training results **we recommend you provide the maximum amount of information possible** if you expect a helpful response, including results plots (train losses, val losses, P, R, mAP), PR curve, confusion matrix, training mosaics, test results and dataset statistics images such as labels.png. All of these are located in your `project/name` directory, typically `yolov5/runs/train/exp`. + +We've put together a full guide for users looking to get the best results on their YOLOv5 trainings below. + +## Dataset + +- **Images per class.** ≥ 1500 images per class recommended +- **Instances per class.** ≥ 10000 instances (labeled objects) per class recommended +- **Image variety.** Must be representative of deployed environment. For real-world use cases we recommend images from different times of day, different seasons, different weather, different lighting, different angles, different sources (scraped online, collected locally, different cameras) etc. +- **Label consistency.** All instances of all classes in all images must be labelled. Partial labelling will not work. +- **Label accuracy.** Labels must closely enclose each object. No space should exist between an object and it's bounding box. No objects should be missing a label. +- **Label verification.** View `train_batch*.jpg` on train start to verify your labels appear correct, i.e. see [example](https://docs.ultralytics.com/yolov5/tutorials/train_custom_data#local-logging) mosaic. +- **Background images.** Background images are images with no objects that are added to a dataset to reduce False Positives (FP). We recommend about 0-10% background images to help reduce FPs (COCO has 1000 background images for reference, 1% of the total). No labels are required for background images. + +COCO Analysis + +## Model Selection + +Larger models like YOLOv5x and [YOLOv5x6](https://github.com/ultralytics/yolov5/releases/tag/v5.0) will produce better results in nearly all cases, but have more parameters, require more CUDA memory to train, and are slower to run. For **mobile** deployments we recommend YOLOv5s/m, for **cloud** deployments we recommend YOLOv5l/x. See our README [table](https://github.com/ultralytics/yolov5#pretrained-checkpoints) for a full comparison of all models. + +

YOLOv5 Models

+ +- **Start from Pretrained weights.** Recommended for small to medium-sized datasets (i.e. [VOC](https://github.com/ultralytics/yolov5/blob/master/data/VOC.yaml), [VisDrone](https://github.com/ultralytics/yolov5/blob/master/data/VisDrone.yaml), [GlobalWheat](https://github.com/ultralytics/yolov5/blob/master/data/GlobalWheat2020.yaml)). Pass the name of the model to the `--weights` argument. Models download automatically from the [latest YOLOv5 release](https://github.com/ultralytics/yolov5/releases). + +```shell +python train.py --data custom.yaml --weights yolov5s.pt + yolov5m.pt + yolov5l.pt + yolov5x.pt + custom_pretrained.pt +``` + +- **Start from Scratch.** Recommended for large datasets (i.e. [COCO](https://github.com/ultralytics/yolov5/blob/master/data/coco.yaml), [Objects365](https://github.com/ultralytics/yolov5/blob/master/data/Objects365.yaml), [OIv6](https://storage.googleapis.com/openimages/web/index.html)). Pass the model architecture YAML you are interested in, along with an empty `--weights ''` argument: + +```bash +python train.py --data custom.yaml --weights '' --cfg yolov5s.yaml + yolov5m.yaml + yolov5l.yaml + yolov5x.yaml +``` + +## Training Settings + +Before modifying anything, **first train with default settings to establish a performance baseline**. A full list of train.py settings can be found in the [train.py](https://github.com/ultralytics/yolov5/blob/master/train.py) argparser. + +- **Epochs.** Start with 300 epochs. If this overfits early then you can reduce epochs. If overfitting does not occur after 300 epochs, train longer, i.e. 600, 1200 etc epochs. +- **Image size.** COCO trains at native resolution of `--img 640`, though due to the high amount of small objects in the dataset it can benefit from training at higher resolutions such as `--img 1280`. If there are many small objects then custom datasets will benefit from training at native or higher resolution. Best inference results are obtained at the same `--img` as the training was run at, i.e. if you train at `--img 1280` you should also test and detect at `--img 1280`. +- **Batch size.** Use the largest `--batch-size` that your hardware allows for. Small batch sizes produce poor batchnorm statistics and should be avoided. +- **Hyperparameters.** Default hyperparameters are in [hyp.scratch-low.yaml](https://github.com/ultralytics/yolov5/blob/master/data/hyps/hyp.scratch-low.yaml). We recommend you train with default hyperparameters first before thinking of modifying any. In general, increasing augmentation hyperparameters will reduce and delay overfitting, allowing for longer trainings and higher final mAP. Reduction in loss component gain hyperparameters like `hyp['obj']` will help reduce overfitting in those specific loss components. For an automated method of optimizing these hyperparameters, see our [Hyperparameter Evolution Tutorial](https://docs.ultralytics.com/yolov5/tutorials/hyperparameter_evolution). + +## Further Reading + +If you'd like to know more, a good place to start is Karpathy's 'Recipe for Training Neural Networks', which has great ideas for training that apply broadly across all ML domains: [http://karpathy.github.io/2019/04/25/recipe/](http://karpathy.github.io/2019/04/25/recipe/) + +Good luck 🍀 and let us know if you have any other questions! diff --git a/ultralytics/docs/yolov5/tutorials/train_custom_data.md b/ultralytics/docs/yolov5/tutorials/train_custom_data.md new file mode 100644 index 0000000000000000000000000000000000000000..2ac3ce244f39f006663020dfe3dc85030fccb39c --- /dev/null +++ b/ultralytics/docs/yolov5/tutorials/train_custom_data.md @@ -0,0 +1,228 @@ +--- +comments: true +description: Learn how to train your data on custom datasets using YOLOv5.

+
+ +Creating a custom model to detect your objects is an iterative process of collecting and organizing images, labeling your objects of interest, training a model, deploying it into the wild to make predictions, and then using that deployed model to collect examples of edge cases to repeat and improve. + +### 1. Create Dataset + +YOLOv5 models must be trained on labelled data in order to learn classes of objects in that data. There are two options for creating your dataset before you start training: + +
+Use Roboflow to create your dataset in YOLO format 🌟 + +!!! note + + Roboflow users can use Ultralytics under the [AGPL license](https://github.com/ultralytics/ultralytics/blob/main/LICENSE) or can request an [Enterprise license](https://ultralytics.com/license) directly from Ultralytics. Be aware that Roboflow does not provide Ultralytics licenses, and it is the responsibility of the user to ensure appropriate licensing. + +### 1.1 Collect Images + +Your model will learn by example. Training on images similar to the ones it will see in the wild is of the utmost importance. Ideally, you will collect a wide variety of images from the same configuration (camera, angle, lighting, etc.) as you will ultimately deploy your project. + +If this is not possible, you can start from [a public dataset](https://universe.roboflow.com/?ref=ultralytics) to train your initial model and then [sample images from the wild during inference](https://blog.roboflow.com/computer-vision-active-learning-tips/?ref=ultralytics) to improve your dataset and model iteratively. + +### 1.2 Create Labels + +Once you have collected images, you will need to annotate the objects of interest to create a ground truth for your model to learn from. + +

+ +[Roboflow Annotate](https://roboflow.com/annotate?ref=ultralytics) is a simple web-based tool for managing and labeling your images with your team and exporting them in [YOLOv5's annotation format](https://roboflow.com/formats/yolov5-pytorch-txt?ref=ultralytics). + +### 1.3 Prepare Dataset for YOLOv5 + +Whether you [label your images with Roboflow](https://roboflow.com/annotate?ref=ultralytics) or not, you can use it to convert your dataset into YOLO format, create a YOLOv5 YAML configuration file, and host it for importing into your training script. + +[Create a free Roboflow account](https://app.roboflow.com/?model=yolov5&ref=ultralytics) +and upload your dataset to a `Public` workspace, label any unannotated images, then generate and export a version of your dataset in `YOLOv5 Pytorch` format. + +Note: YOLOv5 does online augmentation during training, so we do not recommend applying any augmentation steps in Roboflow for training with YOLOv5. But we recommend applying the following preprocessing steps: + +

+ +* **Auto-Orient** - to strip EXIF orientation from your images. +* **Resize (Stretch)** - to the square input size of your model (640x640 is the YOLOv5 default). + +Generating a version will give you a point in time snapshot of your dataset so you can always go back and compare your future model training runs against it, even if you add more images or change its configuration later. + +

+ +Export in `YOLOv5 Pytorch` format, then copy the snippet into your training script or notebook to download your dataset. + +

+ +Now continue with `2. Select a Model`. +
+ +
+Or manually prepare your dataset + +### 1.1 Create dataset.yaml + +[COCO128](https://www.kaggle.com/ultralytics/coco128) is an example small tutorial dataset composed of the first 128 images in [COCO](http://cocodataset.org/#home) train2017. These same 128 images are used for both training and validation to verify our training pipeline is capable of overfitting. [data/coco128.yaml](https://github.com/ultralytics/yolov5/blob/master/data/coco128.yaml), shown below, is the dataset config file that defines 1) the dataset root directory `path` and relative paths to `train` / `val` / `test` image directories (or *.txt files with image paths) and 2) a class `names` dictionary: + +```yaml +# Train/val/test sets as 1) dir: path/to/imgs, 2) file: path/to/imgs.txt, or 3) list: [path/to/imgs1, path/to/imgs2, ..] +path: ../datasets/coco128 # dataset root dir +train: images/train2017 # train images (relative to 'path') 128 images +val: images/train2017 # val images (relative to 'path') 128 images +test: # test images (optional) + +# Classes (80 COCO classes) +names: + 0: person + 1: bicycle + 2: car + ... + 77: teddy bear + 78: hair drier + 79: toothbrush +``` + +### 1.2 Create Labels + +After using an annotation tool to label your images, export your labels to **YOLO format**, with one `*.txt` file per image (if no objects in image, no `*.txt` file is required). The `*.txt` file specifications are: + +- One row per object +- Each row is `class x_center y_center width height` format. +- Box coordinates must be in **normalized xywh** format (from 0 - 1). If your boxes are in pixels, divide `x_center` and `width` by image width, and `y_center` and `height` by image height. +- Class numbers are zero-indexed (start from 0). + +

+ +The label file corresponding to the above image contains 2 persons (class `0`) and a tie (class `27`): + +

+ +### 1.3 Organize Directories + +Organize your train and val images and labels according to the example below. YOLOv5 assumes `/coco128` is inside a `/datasets` directory **next to** the `/yolov5` directory. **YOLOv5 locates labels automatically for each image** by replacing the last instance of `/images/` in each image path with `/labels/`. For example: + +```bash +../datasets/coco128/images/im0.jpg # image +../datasets/coco128/labels/im0.txt # label +``` + +

+
+ +### 2. Select a Model + +Select a pretrained model to start training from. Here we select [YOLOv5s](https://github.com/ultralytics/yolov5/blob/master/models/yolov5s.yaml), the second-smallest and fastest model available. See our README [table](https://github.com/ultralytics/yolov5#pretrained-checkpoints) for a full comparison of all models. + +

YOLOv5 Models

+ +### 3. Train + +Train a YOLOv5s model on COCO128 by specifying dataset, batch-size, image size and either pretrained `--weights yolov5s.pt` (recommended), or randomly initialized `--weights '' --cfg yolov5s.yaml` (not recommended). Pretrained weights are auto-downloaded from the [latest YOLOv5 release](https://github.com/ultralytics/yolov5/releases). + +```bash +python train.py --img 640 --epochs 3 --data coco128.yaml --weights yolov5s.pt +``` + +!!! tip "Tip" + + 💡 Add `--cache ram` or `--cache disk` to speed up training (requires significant RAM/disk resources). + +!!! tip "Tip" + + 💡 Always train from a local dataset. Mounted or network drives like Google Drive will be very slow. + +All training results are saved to `runs/train/` with incrementing run directories, i.e. `runs/train/exp2`, `runs/train/exp3` etc. For more details see the Training section of our tutorial notebook.

Transfer learning is a useful way to quickly retrain a model on new data without having to retrain the entire network. Instead, part of the initial weights are frozen in place, and the rest of the weights are used to compute loss and are updated by the optimizer. This requires less resources than normal training and allows for faster training times, though it may also result in reductions to final trained accuracy.

+ +This example demonstrates how to perform inference using YOLOv8 in C++ with ONNX Runtime and OpenCV's API. + +## Benefits ✨ + +- Friendly for deployment in the industrial sector. +- Faster than OpenCV's DNN inference on both CPU and GPU. +- Supports FP32 and FP16 CUDA acceleration. + +## Exporting YOLOv8 Models 📦 + +To export YOLOv8 models, use the following Python script: + +```python +from ultralytics import YOLO + +# Load a YOLOv8 model +model = YOLO("yolov8n.pt") + +# Export the model +model.export(format="onnx", opset=12, simplify=True, dynamic=False, imgsz=640) +``` + +Alternatively, you can use the following command for exporting the model in the terminal + +```bash +yolo export model=yolov8n.pt opset=12 simplify=True dynamic=False format=onnx imgsz=640,640 +``` + +## Download COCO.yaml file 📂 + +In order to run example, you also need to download coco.yaml. You can download the file manually from [here](https://raw.githubusercontent.com/ultralytics/ultralytics/main/ultralytics/cfg/datasets/coco.yaml) + +## Dependencies ⚙️ + +| Dependency | Version | +| -------------------------------- | -------------- | +| Onnxruntime(linux,windows,macos) | >=1.14.1 | +| OpenCV | >=4.0.0 | +| C++ Standard | >=17 | +| Cmake | >=3.5 | +| Cuda (Optional) | >=11.4 \<12.0 | +| cuDNN (Cuda required) | =8 | + +Note: The dependency on C++17 is due to the usage of the C++17 filesystem feature. + +Note (2): Due to ONNX Runtime, we need to use CUDA 11 and cuDNN 8. Keep in mind that this requirement might change in the future. + +## Build 🛠️ + +1. Clone the repository to your local machine. +1. Navigate to the root directory of the repository. +1. Create a build directory and navigate to it: + +```console +mkdir build && cd build +``` + +4. Run CMake to generate the build files: + +```console +cmake .. +``` + +5. Build the project: + +```console +make +``` + +6. The built executable should now be located in the `build` directory. + +## Usage 🚀 + +```c++ +// CPU inference +DCSP_INIT_PARAM params{ model_path, YOLO_ORIGIN_V8, {imgsz_w, imgsz_h}, 0.1, 0.5, false}; +// GPU inference +DCSP_INIT_PARAM params{ model_path, YOLO_ORIGIN_V8, {imgsz_w, imgsz_h}, 0.1, 0.5, true}; +// Load your image +cv::Mat img = cv::imread(img_path); +// Init Inference Session +char* ret = yoloDetector->CreateSession(params); + +ret = yoloDetector->RunSession(img, res); +``` + +This repository should also work for YOLOv5, which needs a permute operator for the output of the YOLOv5 model, but this has not been implemented yet. diff --git a/ultralytics/examples/YOLOv8-ONNXRuntime-CPP/inference.cpp b/ultralytics/examples/YOLOv8-ONNXRuntime-CPP/inference.cpp new file mode 100644 index 0000000000000000000000000000000000000000..7e9d0aa5169e3b843776d801b0af99f514d9f164 --- /dev/null +++ b/ultralytics/examples/YOLOv8-ONNXRuntime-CPP/inference.cpp @@ -0,0 +1,290 @@ +#include "inference.h" +#include + +#define benchmark + +DCSP_CORE::DCSP_CORE() { + +} + + +DCSP_CORE::~DCSP_CORE() { + delete session;

What Does Region Counting Involve?** + +Region counting is a computational method utilized to ascertain the quantity of objects within a specific area in recorded video or real-time streams. This technique finds frequent application in image processing, computer vision, and pattern recognition, facilitating the analysis and segmentation of objects or features based on their spatial relationships. + +**2. Is Friendly Region Plotting Supported by the Region Counter?** + +The Region Counter offers the capability to create regions in various formats, such as polygons and rectangles. You have the flexibility to modify region attributes, including coordinates, colors, and other details, as demonstrated in the following code: + +```python +counting_regions = [ + { + "name": "YOLOv8 Polygon Region", + "polygon": Polygon( + [(50, 80), (250, 20), (450, 80), (400, 350), (100, 350)] + ), # Polygon with five points (Pentagon) + "counts": 0, + "dragging": False, + "region_color": (255, 42, 4), # BGR Value + "text_color": (255, 255, 255), # Region Text Color + }, + { + "name": "YOLOv8 Rectangle Region", + "polygon": Polygon( + [(200, 250), (440, 250), (440, 550), (200, 550)] + ), # Rectangle with four points + "counts": 0, + "dragging": False, + "region_color": (37, 255, 225), # BGR Value + "text_color": (0, 0, 0), # Region Text Color + }, +] +``` + +**3. Why Combine Region Counting with YOLOv8?** + +YOLOv8 specializes in the detection and tracking of objects in video streams. Region counting complements this by enabling object counting within designated areas, making it a valuable application of YOLOv8. + +**4. How Can I Troubleshoot Issues?** + +To gain more insights during inference, you can include the `--debug` flag in your command: + +```bash +python yolov8_region_counter.py --source "path to video file" --debug +``` + +**5. Can I Employ Other YOLO Versions?** + +Certainly, you have the flexibility to specify different YOLO model weights using the `--weights` option. + +**6. Where Can I Access Additional Information?** + +For a comprehensive guide on using YOLOv8 with Object Tracking, please refer to [Multi-Object Tracking with Ultralytics YOLO](https://docs.ultralytics.com/modes/track/). diff --git a/ultralytics/examples/YOLOv8-Region-Counter/yolov8_region_counter.py b/ultralytics/examples/YOLOv8-Region-Counter/yolov8_region_counter.py new file mode 100644 index 0000000000000000000000000000000000000000..a3e52ef34f6edbd149fb43c97e766afd64accfb5 --- /dev/null +++ b/ultralytics/examples/YOLOv8-Region-Counter/yolov8_region_counter.py @@ -0,0 +1,219 @@ +import argparse +from collections import defaultdict +from pathlib import Path + +import cv2 +import numpy as np +from shapely.geometry import Polygon +from shapely.geometry.point import Point + +from ultralytics import YOLO +from ultralytics.utils.files import increment_path +from ultralytics.utils.plotting import Annotator, colors + +track_history = defaultdict(list) + +current_region = None +counting_regions = [ + { + 'name': 'YOLOv8 Polygon Region', + 'polygon': Polygon([(50, 80), (250, 20), (450, 80), (400, 350), (100, 350)]), # Polygon points + 'counts': 0, + 'dragging': False, + 'region_color': (255, 42, 4), # BGR Value + 'text_color': (255, 255, 255) # Region Text Color + }, + { + 'name': 'YOLOv8 Rectangle Region', + 'polygon': Polygon([(200, 250), (440, 250), (440, 550), (200, 550)]), # Polygon points + 'counts': 0, + 'dragging': False, + 'region_color': (37, 255, 225), # BGR Value + 'text_color': (0, 0, 0), # Region Text Color + }, ] + + +def mouse_callback(event, x, y, flags, param): + """Mouse call back event.""" + global current_region + + # Mouse left button down event + if event == cv2.EVENT_LBUTTONDOWN: + for region in counting_regions: + if region['polygon'].contains(Point((x, y))): + current_region = region + current_region['dragging'] = True + current_region['offset_x'] = x + current_region['offset_y'] = y + + # Mouse move event + elif event == cv2.EVENT_MOUSEMOVE: + if current_region is not None and current_region['dragging']: + dx = x -

What is SAHI?** + +SAHI stands for Slicing, Analysis, and Healing of Images. It is a library designed to optimize object detection algorithms for large-scale and high-resolution images. The library source code is available on [GitHub](https://github.com/obss/sahi). + +**2. Why use SAHI with YOLOv8?** + +SAHI can handle large-scale images by slicing them into smaller, more manageable sizes without compromising the detection quality. This makes it a great companion to YOLOv8, especially when working with high-resolution videos. + +**3. How do I debug issues?** + +You can add the `--debug` flag to your command to print out more information during inference: + +```bash +python yolov8_sahi.py --source "path to video file" --debug +``` + +**4. Can I use other YOLO versions?** + +Yes, you can specify different YOLO model weights using the `--weights` option. + +**5. Where can I find more information?** + +For a full guide to YOLOv8 with SAHI see [https://docs.ultralytics.com/guides/sahi-tiled-inference](https://docs.ultralytics.com/guides/sahi-tiled-inference/). diff --git a/ultralytics/examples/YOLOv8-SAHI-Inference-Video/yolov8_sahi.py b/ultralytics/examples/YOLOv8-SAHI-Inference-Video/yolov8_sahi.py new file mode 100644 index 0000000000000000000000000000000000000000..7ab844174b842bbcb036d73d18e9458a2d0390e4 --- /dev/null +++ b/ultralytics/examples/YOLOv8-SAHI-Inference-Video/yolov8_sahi.py @@ -0,0 +1,111 @@ +import argparse +from pathlib import Path + +import cv2 +from sahi import AutoDetectionModel +from sahi.predict import get_sliced_prediction +from sahi.utils.yolov8 import download_yolov8s_model + +from ultralytics.utils.files import increment_path + + +def run(weights='yolov8n.pt', source='test.mp4', view_img=False, save_img=False, exist_ok=False): + """ + Run object detection on a video using YOLOv8 and SAHI. + + Args: + weights (str): Model weights path. + source (str): Video file path. + view_img (bool): Show results. + save_img (bool): Save results. + exist_ok (bool): Overwrite existing files. + """ + + # Check source path + if not Path(source).exists(): + raise FileNotFoundError(f"Source path '{source}' does not exist.") + + yolov8_model_path = f'models/{weights}' + download_yolov8s_model(yolov8_model_path) + detection_model = AutoDetectionModel.from_pretrained(model_type='yolov8', + model_path=yolov8_model_path, + confidence_threshold=0.3, + device='cpu') + + # Video setup + videocapture = cv2.VideoCapture(source) + frame_width, frame_height = int(videocapture.get(3)), int(videocapture.get(4)) + fps, fourcc = int(videocapture.get(5)), cv2.VideoWriter_fourcc(*'mp4v') + + # Output setup + save_dir = increment_path(Path('ultralytics_results_with_sahi') / 'exp', exist_ok) + save_dir.mkdir(parents=True, exist_ok=True) + video_writer = cv2.VideoWriter(str(save_dir / f'{Path(source).stem}.mp4'), fourcc, fps, (frame_width, frame_height)) + + while videocapture.isOpened(): + success, frame = videocapture.read() + if not success: + break + + results = get_sliced_prediction(frame, + detection_model, + slice_height=512, + slice_width=512, + overlap_height_ratio=0.2, + overlap_width_ratio=0.2) + object_prediction_list = results.object_prediction_list + + boxes_list = [] + clss_list = [] + for ind, _ in enumerate(object_prediction_list): + boxes = object_prediction_list[ind].bbox.minx, object_prediction_list[ind].bbox.miny, \ + object_prediction_list[ind].bbox.maxx, object_prediction_list[ind].bbox.maxy + clss = object_prediction_list[ind].category.name + boxes_list.append(boxes) + clss_list.append(clss) + + for box, cls in zip(boxes_list, clss_list): + x1, y1, x2, y2 = box + cv2.rectangle(frame, (int(x1), int(y1)), (int(x2), int(y2)), (56, 56, 255), 2) + label = str(cls) + t_size = cv2.getTextSize(label, 0, fontScale=0.6, thickness=1)[0] + cv2.rectangle(frame, (int(x1), int(y1) -

To do this, simply make a copy of a tracker config file (for example, `custom_tracker.yaml`) from [ultralytics/cfg/trackers](https://github.com/ultralytics/ultralytics/tree/main/ultralytics/cfg/trackers) and modify any configurations (except the `tracker_type`) as per your needs. + +#### Python + +```python +from ultralytics import YOLO + +# Load the model and run the tracker with a custom configuration file +model = YOLO("yolov8n.pt") +results = model.track( + source="https://youtu.be/LNwODJXcvt4", tracker="custom_tracker.yaml" +) +``` + +#### CLI + +```bash +# Load the model and run the tracker with a custom configuration file using the command line interface +yolo track model=yolov8n.pt source="https://youtu.be/LNwODJXcvt4" tracker='custom_tracker.yaml' +``` + +For a comprehensive list of tracking arguments, refer to the [ultralytics/cfg/trackers](https://github.com/ultralytics/ultralytics/tree/main/ultralytics/cfg/trackers) page. + +## Python Examples + +### Persisting Tracks Loop + +Here is a Python script using OpenCV (`cv2`) and YOLOv8 to run object tracking on video frames. This script still assumes you have already installed the necessary packages (`opencv-python` and `ultralytics`). The `persist=True` argument tells the tracker than the current image or frame is the next in a sequence and to expect tracks from the previous image in the current image. + +#### Python + +```python +import cv2 +from ultralytics import YOLO + +# Load the YOLOv8 model +model = YOLO("yolov8n.pt") + +# Open the video file +video_path = "path/to/video.mp4" +cap = cv2.VideoCapture(video_path) + +# Loop through the video frames +while cap.isOpened(): + # Read a frame from the video + success, frame = cap.read() + + if success: + # Run YOLOv8 tracking on the frame, persisting tracks between frames + results = model.track(frame, persist=True) + + # Visualize the results on the frame + annotated_frame = results[0].plot() + + # Display the annotated frame + cv2.imshow("YOLOv8 Tracking", annotated_frame) + + # Break the loop if 'q' is pressed + if cv2.waitKey(1) & 0xFF == ord("q"): + break + else: + # Break the loop if the end of the video is reached + break + +# Release the video capture object and close the display window +cap.release() +cv2.destroyAllWindows() +``` + +Please note the change from `model(frame)` to `model.track(frame)`, which enables object tracking instead of simple detection. This modified script will run the tracker on each frame of the video, visualize the results, and display them in a window. The loop can be exited by pressing 'q'. + +### Plotting Tracks Over Time + +Visualizing object tracks over consecutive frames can provide valuable insights into the movement patterns and behavior of detected objects within a video. With Ultralytics YOLOv8, plotting these tracks is a seamless and efficient process. + +In the following example, we demonstrate how to utilize YOLOv8's tracking capabilities to plot the movement of detected objects across multiple video frames. This script involves opening a video file, reading it frame by frame, and utilizing the YOLO model to identify and track various objects. By retaining the center points of the detected bounding boxes and connecting them, we can draw lines that represent the paths followed by the tracked objects. + +#### Python + +```python +from collections import defaultdict + +import cv2 +import numpy as np + +from ultralytics import YOLO + +# Load the YOLOv8 model +model = YOLO("yolov8n.pt") + +# Open the video file +video_path = "path/to/video.mp4" +cap = cv2.VideoCapture(video_path) + +# Store the track history +track_history = defaultdict(lambda: []) + +# Loop through the video frames +while cap.isOpened(): + # Read a frame from the video + success, frame = cap.read() + + if success: + # Run YOLOv8 tracking on the frame, persisting tracks between frames + results = model.track(frame, persist=True) + + # Get the boxes and track IDs + boxes = results[0].boxes.xywh.cpu() + track_ids = results[0].boxes.id.int().cpu().tolist() + + # Visualize the results on the frame + annotated_frame = results[0].plot() + + # Plot the tracks + for box, track_id in zip(boxes, track_ids): + x, y, w, h = box + track = track_history[track_id] + track.append((float(x), float(y))) # x, y center point + if len(track) > 30: # retain 90 tracks for 90 frames + track.pop(0) + + # Draw the tracking lines + points = np.hstack(track).astype(np.int32).reshape((-1, 1, 2)) + cv2.polylines( + annotated_frame, + [points], + isClosed=False, + color=(230, 230, 230), + thickness=10, + ) + + # Display the annotated frame + cv2.imshow("YOLOv8 Tracking", annotated_frame) + + # Break the loop if 'q' is pressed + if cv2.waitKey(1) & 0xFF == ord("q"): + break + else: + # Break the loop if the end of the video is reached + break + +# Release the video capture object and close the display window +cap.release() +cv2.destroyAllWindows() +``` + +### Multithreaded Tracking + +Multithreaded tracking provides the capability to run object tracking on multiple video streams simultaneously. This is particularly useful when handling multiple video inputs, such as from multiple surveillance cameras, where concurrent processing can greatly enhance efficiency and performance. + +In the provided Python script, we make use of Python's `threading` module to run multiple instances of the tracker concurrently. Each thread is responsible for running the tracker on one video file, and all the threads run simultaneously in the background. + +To ensure that each thread receives the correct parameters (the video file and the model to use), we define a function `run_tracker_in_thread` that accepts these parameters and contains the main tracking loop. This function reads the video frame by frame, runs the tracker, and displays the results. + +Two different models are used in this example: `yolov8n.pt` and `yolov8n-seg.pt`, each tracking objects in a different video file. The video files are specified in `video_file1` and `video_file2`. + +The `daemon=True` parameter in `threading.Thread` means that these threads will be closed as soon as the main program finishes. We then start the threads with `start()` and use `join()` to make the main thread wait until both tracker threads have finished. + +Finally, after all threads have completed their task, the windows displaying the results are closed using `cv2.destroyAllWindows()`. + +#### Python + +```python +import threading + +import cv2 +from ultralytics import YOLO + + +def run_tracker_in_thread(filename, model): + video = cv2.VideoCapture(filename) + frames = int(video.get(cv2.CAP_PROP_FRAME_COUNT)) + for _ in range(frames): + ret, frame = video.read() + if ret: + results = model.track(source=frame, persist=True) + res_plotted = results[0].plot() + cv2.imshow("p", res_plotted) + if cv2.waitKey(1) == ord("q"): + break + + +# Load the models +model1 = YOLO("yolov8n.pt") +model2 = YOLO("yolov8n-seg.pt") + +# Define the video files for the trackers +video_file1 = "path/to/video1.mp4" +video_file2 = "path/to/video2.mp4" + +# Create the tracker threads +tracker_thread1 = threading.Thread( + target=run_tracker_in_thread, args=(video_file1, model1), daemon=True +) +tracker_thread2 = threading.Thread( + target=run_tracker_in_thread, args=(video_file2, model2), daemon=True +) + +# Start the tracker threads +tracker_thread1.start() +tracker_thread2.start() + +# Wait for the tracker threads to finish +tracker_thread1.join() +tracker_thread2.join() + +# Clean up and close windows +cv2.destroyAllWindows() +``` + +This example can easily be extended to handle more video files and models by creating more threads and applying the same methodology. + +## Contribute New Trackers + +Are you proficient in multi-object tracking and have successfully implemented or adapted a tracking algorithm with Ultralytics YOLO?
