欢迎！我们是一个非常友好的社区，非常高兴您想要帮助我们让这个应用程序变得更好。但是，请您遵循一些通用准则以保持组织有序。
|
| 4 |
+
|
| 5 |
+
1. 确保为您要修复的错误或要添加的功能创建了一个[问题](https://github.com/imClumsyPanda/langchain-ChatGLM/issues)，尽可能保持它们小。
|
| 6 |
+
2. 请使用 `git pull --rebase` 来拉取和衍合上游的更新。
|
| 7 |
+
3. 将提交合并为格式良好的提交。在提交说明中单独一行提到要解决的问题，如`Fix #<bug>`（有关更多可以使用的关键字，请参见[将拉取请求链接到问题](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue)）。
|
| 8 |
+
4. 推送到`dev`。在说明中提到正在解决的问题。

# Contribution Guide
|
| 13 |
+
|

+
Welcome! We're a pretty friendly community, and we're thrilled that you want to help make this app even better. However, we ask that you follow some general guidelines to keep things organized around here.
|
| 15 |
+
|
| 16 |
+
1. Make sure an [issue](https://github.com/imClumsyPanda/langchain-ChatGLM/issues) is created for the bug you're about to fix, or feature you're about to add. Keep them as small as possible.
|
| 17 |
+
|
| 18 |
+
2. Please use `git pull --rebase` to fetch and merge updates from the upstream.
|
| 19 |
+
|
| 20 |
+
3. Rebase commits into well-formatted commits. Mention the issue being resolved in the commit message on a line all by itself like `Fixes #<bug>` (refer to [Linking a pull request to an issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue) for more keywords you can use).
|
| 21 |
+
|
| 22 |
+
4. Push into `dev`. Mention which bug is being resolved in the description.

"Licensor" shall mean the copyright owner or entity authorized by

+
the copyright owner that is granting the License.
|

| 18 |
+

including but not limited to software source code, documentation
|
| 28 |
+
source, and configuration files.
|

|
| 34 |
+
|

+
|
| 40 |
+
"Derivative Works" shall mean any work, whether in Source or Object

form, that is based on (or derived from) the Work and for which the
|

|
| 43 |
+
represent, as a whole, an original work of authorship. For the purposes
|
| 44 |
+
of this License, Derivative Works shall not include works that remain
|
| 45 |
+
separable from, or merely link (or bind by name) to the interfaces of,
|
| 46 |
+
the Work and Derivative Works thereof.
|
| 47 |
+
|
| 48 |
+
"Contribution" shall mean any work of authorship, including
|
| 49 |
+
the original version of the Work and any modifications or additions
|
| 50 |
+
to that Work or Derivative Works thereof, that is intentionally
|
| 51 |
+
submitted to Licensor for inclusion in the Work by the copyright owner
|
| 52 |
+
or by an individual or Legal Entity authorized to submit on behalf of
|
| 53 |
+
the copyright owner. For the purposes of this definition, "submitted"
|
| 54 |
+
means any form of electronic, verbal, or written communication sent
|
| 55 |
+
to the Licensor or its representatives, including but not limited to
|
| 56 |
+
communication on electronic mailing lists, source code control systems,
|
| 57 |
+
and issue tracking systems that are managed by, or on behalf of, the
|
| 58 |
+
Licensor for the purpose of discussing and improving the Work, but
|
| 59 |
+
excluding communication that is conspicuously marked or otherwise
|
| 60 |
+
designated in writing by the copyright owner as "Not a Contribution."
|
| 61 |
+
|
| 62 |
+
"Contributor" shall mean Licensor and any individual or Legal Entity
|
| 63 |
+
on behalf of whom a Contribution has been received by Licensor and
|
| 64 |
+
subsequently incorporated within the Work.
|
| 65 |
+
|
| 66 |
+
2. Grant of Copyright License. Subject to the terms and conditions of
|
| 67 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 68 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 69 |
+
copyright license to reproduce, prepare Derivative Works of,
|
| 70 |
+
publicly display, publicly perform, sublicense, and distribute the
|
| 71 |
+
Work and such Derivative Works in Source or Object form.
|
| 72 |
+
|
| 73 |
+
3. Grant of Patent License. Subject to the terms and conditions of
|
| 74 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 75 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 76 |
+
(except as stated in this section) patent license to make, have made,
|
| 77 |
+
use, offer to sell, sell, import, and otherwise transfer the Work,
|
| 78 |
+
where such license applies only to those patent claims licensable
|
| 79 |
+
by such Contributor that are necessarily infringed by their
|
| 80 |
+
Contribution(s) alone or by combination of their Contribution(s)
|
| 81 |
+
with the Work to which such Contribution(s) was submitted. If You
|
| 82 |
+
institute patent litigation against any entity (including a
|
| 83 |
+
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
| 84 |
+
or a Contribution incorporated within the Work constitutes direct
|
| 85 |
+
or contributory patent infringement, then any patent licenses
|
| 86 |
+
granted to You under this License for that Work shall terminate
|
| 87 |
+
as of the date such litigation is filed.
|
| 88 |
+
|
| 89 |
+
4. Redistribution. You may reproduce and distribute copies of the
|
| 90 |
+
Work or Derivative Works thereof in any medium, with or without
|
| 91 |
+
modifications, and in Source or Object form, provided that You
|
| 92 |
+
meet the following conditions:
|
| 93 |
+
|
| 94 |
+
(a) You must give any other recipients of the Work or
|
| 95 |
+
Derivative Works a copy of this License; and
|
| 96 |
+
|
| 97 |
+
(b) You must cause any modified files to carry prominent notices
|
| 98 |
+
stating that You changed the files; and
|
| 99 |
+
|
| 100 |
+
(c) You must retain, in the Source form of any Derivative Works
|
| 101 |
+
that You distribute, all copyright, patent, trademark, and
|
| 102 |
+
attribution notices from the Source form of the Work,
|
| 103 |
+
excluding those notices that do not pertain to any part of
|
| 104 |
+
the Derivative Works; and
|
| 105 |
+
|
| 106 |
+
(d) If the Work includes a "NOTICE" text file as part of its
|
| 107 |
+
distribution, then any Derivative Works that You distribute must
|
| 108 |
+
include a readable copy of the attribution notices contained
|
| 109 |
+
within such NOTICE file, excluding those notices that do not
|
| 110 |
+
pertain to any part of the Derivative Works, in at least one
|
| 111 |
+
of the following places: within a NOTICE text file distributed
|
| 112 |
+
as part of the Derivative Works; within the Source form or
|
| 113 |
+
documentation, if provided along with the Derivative Works; or,
|
| 114 |
+
within a display generated by the Derivative Works, if and
|
| 115 |
+
wherever such third-party notices normally appear. The contents
|
| 116 |
+
of the NOTICE file are for informational purposes only and
|
| 117 |
+
do not modify the License. You may add Your own attribution
|
| 118 |
+
notices within Derivative Works that You distribute, alongside
|
| 119 |
+
or as an addendum to the NOTICE text from the Work, provided
|
| 120 |
+
that such additional attribution notices cannot be construed
|
| 121 |
+
as modifying the License.
|
| 122 |
+
|
| 123 |
+
You may add Your own copyright statement to Your modifications and
|
| 124 |
+
may provide additional or different license terms and conditions
|
| 125 |
+
for use, reproduction, or distribution of Your modifications, or
|
| 126 |
+
for any such Derivative Works as a whole, provided Your use,
|
| 127 |
+
reproduction, and distribution of the Work otherwise complies with
|
| 128 |
+
the conditions stated in this License.
|
| 129 |
+
|
| 130 |
+
5. Submission of Contributions. Unless You explicitly state otherwise,
|
| 131 |
+
any Contribution intentionally submitted for inclusion in the Work
|
| 132 |
+
by You to the Licensor shall be under the terms and conditions of
|
| 133 |
+
this License, without any additional terms or conditions.
|
| 134 |
+
Notwithstanding the above, nothing herein shall supersede or modify
|
| 135 |
+
the terms of any separate license agreement you may have executed
|
| 136 |
+
with Licensor regarding such Contributions.
|
| 137 |
+
|
| 138 |
+
6. Trademarks. This License does not grant permission to use the trade
|
| 139 |
+
names, trademarks, service marks, or product names of the Licensor,
|
| 140 |
+
except as required for reasonable and customary use in describing the
|
| 141 |
+
origin of the Work and reproducing the content of the NOTICE file.
|
| 142 |
+
|
| 143 |
+
7. Disclaimer of Warranty. Unless required by applicable law or
|
| 144 |
+
agreed to in writing, Licensor provides the Work (and each
|
| 145 |
+
Contributor provides its Contributions) on an "AS IS" BASIS,
|
| 146 |
+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
| 147 |
+
implied, including, without limitation, any warranties or conditions
|
| 148 |
+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
| 149 |
+
PARTICULAR PURPOSE. You are solely responsible for determining the
|
| 150 |
+
appropriateness of using or redistributing the Work and assume any
|
| 151 |
+
risks associated with Your exercise of permissions under this License.
|
| 152 |
+
|
| 153 |
+
8. Limitation of Liability. In no event and under no legal theory,
|
| 154 |
+
whether in tort (including negligence), contract, or otherwise,
|
| 155 |
+
unless required by applicable law (such as deliberate and grossly
|
| 156 |
+
negligent acts) or agreed to in writing, shall any Contributor be
|
| 157 |
+
liable to You for damages, including any direct, indirect, special,
|
| 158 |
+
incidental, or consequential damages of any character arising as a
|
| 159 |
+
result of this License or out of the use or inability to use the
|
| 160 |
+
Work (including but not limited to damages for loss of goodwill,
|
| 161 |
+
work stoppage, computer failure or malfunction, or any and all
|
| 162 |
+
other commercial damages or losses), even if such Contributor
|
| 163 |
+
has been advised of the possibility of such damages.
|
| 164 |
+
|
| 165 |
+
9. Accepting Warranty or Additional Liability. While redistributing
|
| 166 |
+
the Work or Derivative Works thereof, You may choose to offer,
|
| 167 |
+
and charge a fee for, acceptance of support, warranty, indemnity,
|
| 168 |
+
or other liability obligations and/or rights consistent with this
|
| 169 |
+
License. However, in accepting such obligations, You may act only
|
| 170 |
+
on Your own behalf and on Your sole responsibility, not on behalf
|
| 171 |
+
of any other Contributor, and only if You agree to indemnify,
|
| 172 |
+
defend, and hold each Contributor harmless for any liability
|
| 173 |
+
incurred by, or claims asserted against, such Contributor by reason
|
| 174 |
+
of your accepting any such warranty or additional liability.
|
| 175 |
+
|
| 176 |
+
END OF TERMS AND CONDITIONS

🤖️ 一种利用 [langchain](https://github.com/hwchase17/langchain) 思想实现的基于本地知识库的问答应用，目标期望建立一套对中文场景与开源模型支持友好、可离线运行的知识库问答解决方案。
|
| 8 |
+
|
| 9 |
+
💡 受 [GanymedeNil](https://github.com/GanymedeNil) 的项目 [document.ai](https://github.com/GanymedeNil/document.ai) 和 [AlexZhangji](https://github.com/AlexZhangji) 创建的 [ChatGLM-6B Pull Request](https://github.com/THUDM/ChatGLM-6B/pull/216) 启发，建立了全流程可使用开源模型实现的本地知识库问答应用。现已支持使用 [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B) 等大语言模型直接接入，或通过 [fastchat](https://github.com/lm-sys/FastChat) api 形式接入 Vicuna, Alpaca, LLaMA, Koala, RWKV 等模型。
|
| 10 |
+
|
| 11 |
+
✅ 本项目中 Embedding 默认选用的是 [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main)，LLM 默认选用的是 [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B)。依托上述模型，本项目可实现全部使用**开源**模型**离线私有部署**。
|
| 12 |
+
|
| 13 |
+
⛓️ 本项目实现原理如下图所示，过程包括加载文件 -> 读取文本 -> 文本分割 -> 文本向量化 -> 问句向量化 -> 在文本向量中匹配出与问句向量最相似的`top k`个 -> 匹配出的文本作为上下文和问题一起添加到`prompt`中 -> 提交给`LLM`生成回答。

本项目中默认选用的 Embedding 模型 [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main) 约占用显存 3GB，也可修改为在 CPU 中运行。
|
| 62 |
+
|
| 63 |
+
## Docker 部署
|
| 64 |
+
为了能让容器使用主机GPU资源，需要在主机上安装 [NVIDIA Container Toolkit](https://github.com/NVIDIA/nvidia-container-toolkit)。具体安装步骤如下：
|
| 65 |
+
```shell
|
| 66 |
+
sudo apt-get update
|
| 67 |
+
sudo apt-get install -y nvidia-container-toolkit-base
|
| 68 |
+
sudo systemctl daemon-reload
|
| 69 |
+
sudo systemctl restart docker
|
| 70 |
+
```
|
| 71 |
+
安装完成后，可以使用以下命令编译镜像和启动容器：
|
| 72 |
+
```
|
| 73 |
+
docker build -f Dockerfile-cuda -t chatglm-cuda:latest .
|
| 74 |
+
docker run --gpus all -d --name chatglm -p 7860:7860 chatglm-cuda:latest
|
| 75 |
+
|
| 76 |
+
#若要使用离线模型，请配置好模型路径，然后此repo挂载到Container
|
| 77 |
+
docker run --gpus all -d --name chatglm -p 7860:7860 -v ~/github/langchain-ChatGLM:/chatGLM chatglm-cuda:latest
|
| 78 |
+
```
|
| 79 |
+
|
| 80 |
+
|
| 81 |
+

|
| 96 |
+
|
| 97 |
+
### 2. 设置模型默认参数
|
| 98 |
+
|
| 99 |
+
在开始执行 Web UI 或命令行交互前，请先检查 [configs/model_config.py](configs/model_config.py) 中的各项模型参数设计是否符合需求。
|
| 100 |
+
|
| 101 |
+
如需通过 fastchat 以 api 形式调用 llm，请参考 [fastchat 调用实现](docs/fastchat.md)
|
| 102 |
+
|
| 103 |
+
### 3. 执行脚本体验 Web UI 或命令行交互
|
| 104 |
+
|
| 105 |
+
> 注：鉴于环境部署过程中可能遇到问题，建议首先测试命令行脚本。建议命令行脚本测试可正常运行后再运行 Web UI。
|
| 106 |
+
|
| 107 |
+
执行 [cli_demo.py](cli_demo.py) 脚本体验**命令行交互**：
|
| 108 |
+
```shell
|
| 109 |
+
$ python cli_demo.py
|
| 110 |
+
```
|
| 111 |
+
|
| 112 |
+
或执行 [webui.py](webui.py) 脚本体验 **Web 交互**
|
| 113 |
+
|
| 114 |
+
```shell

| 116 |
+
```
|
| 117 |
+
|
| 118 |
+
或执行 [api.py](api.py) 利用 fastapi 部署 API
|
| 119 |
+
```shell
|
| 120 |
+
$ python api.py
|
| 121 |
+
```
|
| 122 |
+
或成功部署 API 后，执行以下脚本体验基于 VUE 的前端页面
|
| 123 |
+
```shell
|
| 124 |
+
$ cd views
|
| 125 |
+
|
| 126 |
+
$ pnpm i
|
| 127 |
+
|
| 128 |
+
$ npm run dev
|
| 129 |
+
```
|
| 130 |
+
|
| 131 |
+
VUE 前端界面如下图所示：
|
| 132 |
+
1. `对话` 界面
|
| 133 |
+
|
| 134 |
+
2. `知识库问答` 界面
|
| 135 |

+
|
| 144 |
+
3. `模型配置` Tab 界面
|
| 145 |
+
|
| 146 |
+
|
| 147 |
+
Web UI 可以实现如下功能：
|
| 148 |
+
|
| 149 |
+
1. 运行前自动读取`configs/model_config.py`中`LLM`及`Embedding`模型枚举及默认模型设置运行模型，如需重新加载模型，可在 `模型配置` Tab 重新选择后点击 `重新加载模型` 进行模型加载；
|
| 150 |
+
2. 可手动调节保留对话历史长度、匹配知识库文段数量，可根据显存大小自行调节；
|
| 151 |
+
3. `对话` Tab 具备模式选择功能，可选择 `LLM对话` 与 `知识库问答` 模式进行对话，支持流式对话；
|
| 152 |
+
4. 添加 `配置知识库` 功能，支持选择已有知识库或新建知识库，并可向知识库中**新增**上传文件/文件夹，使用文件上传组件选择好文件后点击 `上传文件并加载知识库`，会将所选上传文档数据加载至知识库中，并基于更新后知识库进行问答；
|
| 153 |
+
5. 新增 `知识库测试 Beta` Tab，可用于测试不同文本切分方法与检索相关度阈值设置，暂不支持将测试参数作为 `对话` Tab 设置参数。
|
| 154 |
+
6. 后续版本中将会增加对知识库的修改或删除，及知识库中已导入文件的查看。
|

使用 langchain 接入 ChatGLM-6B 项目的 README.md 文件后 ChatGLM 的回答：
|
| 178 |
+
>ChatGLM-6B 是一个基于深度学习的自然语言处理模型,它在回答问题方面表现出色。但是,它也有一些局限性,具体如下:
|
| 179 |
+
>1. 语言理解有限:ChatGLM-6B 只学习了中文自然语言,对于其他语言可能会存在理解上的局限性。
|
| 180 |
+
>2. 知识储备不足:ChatGLM-6B 的训练数据集只包含了中文语料,因此���可能无法回答一些非中文的问题或者某些特定领域的问题。
|
| 181 |
+
>3. 数据量有限:ChatGLM-6B 的训练数据集只有几百万条记录,因此它可能无法回答一些非常具体或者复杂的问题。
|
| 182 |
+
>
|
| 183 |
+
>为了改进 ChatGLM-6B,可以考虑以下几个方面:
|
| 184 |
+
>1. 学习更多的语言知识:可以学习其他语言的自然语言处理技术,扩大语言理解的范围。
|
| 185 |
+
>2. 扩大知识储备:可以收集更多的中文语料,或者使用其他语言的数据集来扩充知识储备。
|
| 186 |
+
>3. 增加数据量:可以使用更大的数据集来训练 ChatGLM-6B,提高模型的表现。
|
| 187 |
+
>4. 引入更多的评估指标:可以引入更多的评估指标来评估模型的表现,从而发现 ChatGLM-6B 存在的不足和局限性。
|
| 188 |
+
>5. 改进模型架构:可以改进 ChatGLM-6B 的模型架构,提高模型的性能和表现。例如,可以使用更大的神经网络或者改进的卷积神经网络结构。

+
🤖️ This is a ChatGLM application based on local knowledge, implemented using [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B) and [langchain](https://github.com/hwchase17/langchain).
|
| 10 |
+
|
| 11 |
+
💡 Inspired by [document.ai](https://github.com/GanymedeNil/document.ai) and [Alex Zhangji](https://github.com/AlexZhangji)'s [ChatGLM-6B Pull Request](https://github.com/THUDM/ChatGLM-6B/pull/216), this project establishes a local knowledge question-answering application using open-source models.
|
| 12 |
+
|
| 13 |
+
✅ The embeddings used in this project are [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main), and the LLM is [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B). Relying on these models, this project enables the use of **open-source** models for **offline private deployment**.
|
| 14 |
+
|
| 15 |
+
⛓️ The implementation principle of this project is illustrated in the figure below. The process includes loading files -> reading text -> text segmentation -> text vectorization -> question vectorization -> matching the top k most similar text vectors to the question vector -> adding the matched text to `prompt` along with the question as context -> submitting to `LLM` to generate an answer.

+
🚩 This project does not involve fine-tuning or training; however, fine-tuning or training can be employed to optimize the effectiveness of this project.

## DEMO
|
| 193 |
+
|
| 194 |
+
Using the question "What are the limitations of ChatGLM-6B and how can they be improved?" as an example:
|
| 195 |
+
|
| 196 |
+
Without using langchain to access local documents:
|
| 197 |
+
|
| 198 |
+
> ChatGLM-6B is a chatbot based on GPT-3, and its limitations are mainly reflected in the following aspects:
|
| 199 |
+
>
|
| 200 |
+
> 1. Language model accuracy: Although GPT-3 is a large language model with relatively high accuracy, it still has some limitations. For instance, it may not be able to accurately understand certain dialects, accents, or complex sentence structures.
|
| 201 |
+
> 2. Completeness of the knowledge graph: GPT-3 can generate some knowledge graphs, but its completeness and accuracy may not be sufficient. For example, it may struggle to accurately understand specific domain expertise and terminology.
|
| 202 |
+
> 3. Coherence of dialogue generation: While GPT-3 can generate somewhat coherent dialogues, they may not always be natural. For instance, it may generate false, incoherent dialogue or misinterpret the user's intent.
|
| 203 |
+
>
|
| 204 |
+
> To improve ChatGLM-6B, consider the following aspects:
|
| 205 |
+
>
|
| 206 |
+
> 1. Enhance the accuracy of the language model: The accuracy of the language model can be improved by increasing the training data, using better language model architectures, and optimizing the model training process.
|
| 207 |
+
> 2. Strengthen the integrity of the knowledge graph: The integrity of the knowledge graph can be enhanced by increasing its dimensions, employing better knowledge graph construction methods, and optimizing the knowledge graph's matching algorithm.
|
| 208 |
+
> 3. Boost the coherence of dialogue generation: The coherence of dialogue generation can be improved by augmenting the context information of the dialogue generation model, utilizing better context information extraction methods, and optimizing the dialogue generation model's algorithm.
|
| 209 |
+
> 4. Incorporate more human feedback: Human feedback can help ChatGLM-6B better understand users' intentions and needs, thereby improving the quality and accuracy of dialogue generation. More human feedback can be introduced by involving more human agents and using human feedback collectors.

ChatGLM's answer after using LangChain to access the README.md file of the ChatGLM-6B project:
|
| 212 |
+
>ChatGLM-6B is a deep learning-based natural language processing model that excels at answering questions. However, it also has some limitations, as follows:
|
| 213 |
+
>1. Limited language understanding: ChatGLM-6B has been primarily trained on Chinese natural language, and its understanding of other languages may be limited.
|
| 214 |
+
>2. Insufficient knowledge base: The training dataset of ChatGLM-6B contains only a Chinese corpus, so it may not be able to answer non-Chinese questions or queries in specific domains.
|
| 215 |
+
>3. Limited data volume: ChatGLM-6B's training dataset has only a few million records, which may hinder its ability to answer very specific or complex questions.
|
| 216 |
+
>
|
| 217 |
+
>To improve ChatGLM-6B, consider the following aspects:
|
| 218 |
+
>1. Expand language knowledge: Learn natural language processing techniques in other languages to broaden the model's language understanding capabilities.
|
| 219 |
+
>2. Broaden the knowledge base: Collect more Chinese corpora or use datasets in other languages to expand the model's knowledge base.
|
| 220 |
+
>3. Increase data volume: Use larger datasets to train ChatGLM-6B, which can improve the model's performance.
