Tool to run Cython files (.pyx) into .c and .cpp.
TODO:
- Add support for dynamically selecting in-process Cython
through CYTHONINPROCESS variable.
- Have a CYTHONCPP option which turns on C++ in flags and
changes output extension at the same time
VARIABLES:
- CYTHON - The path to the "cython" command line tool.
- CYTHONFLAGS - Flags to pass to the "cython" command line tool.

----------

The data to center and scale.
axis : int (0 by default)
axis used to compute the means and standard deviations along. If 0,
independently standardize each feature, otherwise (if 1) standardize

Notes
-----
This implementation will refuse to center scipy.sparse matrices
since it would make them non-sparse and would potentially crash the
program with memory exhaustion problems.
Instead the caller is expected to either set explicitly
`with_mean=False` (in that case, only variance scaling will be
performed on the features of the CSR matrix) or to call `X.toarray()`
if he/she expects the materialized dense array to fit in memory.
To avoid memory copy the caller should pass a CSR matrix.

"""Standardize features by removing the mean and scaling to unit variance
Centering and scaling happen independently on each feature by computing
the relevant statistics on the samples in the training set. Mean and
standard deviation are then stored to be used on later data using the
`transform` method.
Standardization of a dataset is a common requirement for many
machine learning estimators: they might behave badly if the
individual feature do not more or less look like standard normally
distributed data (e.g. Gaussian with 0 mean and unit variance).
For instance many elements used in the objective function of
a learning algorithm (such as the RBF kernel of Support Vector
Machines or the L1 and L2 regularizers of linear models) assume that
all features are centered around 0 and have variance in the same
order. If a feature has a variance that is orders of magnitude larger
that others, it might dominate the objective function and make the
estimator unable to learn from other features correctly as expected.
Read more in the :ref:`User Guide <preprocessing_scaler>`.
Parameters
----------
with_mean : boolean, True by default
If True, center the data before scaling.
This does not work (and will raise an exception) when attempted on
sparse matrices, because centering them entails building a dense
matrix which in common use cases is likely to be too large to fit in
memory.
with_std : boolean, True by default
If True, scale the data to unit variance (or equivalently,
unit standard deviation).
copy : boolean, optional, default True
If False, try to avoid a copy and do inplace scaling instead.
This is not guaranteed to always work inplace; e.g. if the data is
not a NumPy array or scipy.sparse CSR matrix, a copy may still be
returned.
Attributes
----------
mean_ : array of floats with shape [n_features]
The mean value for each feature in the training set.
std_ : array of floats with shape [n_features]
The standard deviation for each feature in the training set.

"""Scale features using statistics that are robust to outliers.
This Scaler removes the median and scales the data according to
the Interquartile Range (IQR). The IQR is the range between the 1st
quartile (25th quantile) and the 3rd quartile (75th quantile).
Centering and scaling happen independently on each feature (or each
sample, depending on the `axis` argument) by computing the relevant
statistics on the samples in the training set. Median and interquartile
range are then stored to be used on later data using the `transform`
method.
Standardization of a dataset is a common requirement for many
machine learning estimators. Typically this is done by removing the mean
and scaling to unit variance. However, outliers can often influence the
sample mean / variance in a negative way. In such cases, the median and
the interquartile range often give better results.
Read more in the :ref:`User Guide <preprocessing_scaler>`.
Parameters
----------
with_centering : boolean, True by default
If True, center the data before scaling.
This does not work (and will raise an exception) when attempted on
sparse matrices, because centering them entails building a dense
matrix which in common use cases is likely to be too large to fit in
memory.
with_scaling : boolean, True by default
If True, scale the data to interquartile range.
copy : boolean, optional, default is True
If False, try to avoid a copy and do inplace scaling instead.
This is not guaranteed to always work inplace; e.g. if the data is
not a NumPy array or scipy.sparse CSR matrix, a copy may still be
returned.
Attributes
----------
center_ : array of floats
The median value for each feature in the training set.
scale_ : array of floats

"""Encode categorical integer features using a one-hot aka one-of-K scheme.
The input to this transformer should be a matrix of integers, denoting
the values taken on by categorical (discrete) features. The output will be
a sparse matrix where each column corresponds to one possible value of one
feature. It is assumed that input features take on values in the range
[0, n_values).
This encoding is needed for feeding categorical data to many scikit-learn
estimators, notably linear models and SVMs with the standard kernels.
Read more in the :ref:`User Guide <preprocessing_categorical_features>`.
Parameters
----------
n_values : 'auto', int or array of ints
Number of values per feature.
- 'auto' : determine value range from training data.
- int : maximum value for all features.
- array : maximum value per feature.
categorical_features: "all" or array of indices or mask
Specify what features are treated as categorical.
- 'all' (default): All features are treated as categorical.
- array of indices: Array of categorical feature indices.
- mask: Array of length n_features and with dtype=bool.
Non-categorical features are always stacked to the right of the matrix.
dtype : number type, default=np.float
Desired dtype of output.
sparse : boolean, default=True
Will return sparse matrix if set True else will return an array.
handle_unknown : str, 'error' or 'ignore'
Whether to raise an error or ignore if a unknown categorical feature is
present during transform.
Attributes
----------
active_features_ : array
Indices for active features, meaning values that actually occur
in the training set. Only available when n_values is ``'auto'``.
feature_indices_ : array of shape (n_features,)
Indices to feature ranges.
Feature ``i`` in the original data is mapped to features
from ``feature_indices_[i]`` to ``feature_indices_[i+1]``
(and then potentially masked by `active_features_` afterwards)
n_values_ : array of shape (n_features,)
Maximum number of values per feature.
Examples
--------
Given a dataset with three features and two samples, we let the encoder
find the maximum value per feature and transform the data to a binary
one-hot encoding.
>>> from sklearn.preprocessing import OneHotEncoder
>>> enc = OneHotEncoder()
>>> enc.fit([[0, 0, 3], [1, 1, 0], [0, 2, 1], \
[1, 0, 2]]) # doctest: +ELLIPSIS
OneHotEncoder(categorical_features='all', dtype=<... 'float'>,
handle_unknown='error', n_values='auto', sparse=True)
>>> enc.n_values_
array([2, 3, 4])
>>> enc.feature_indices_
array([0, 2, 5, 9])
>>> enc.transform([[0, 1, 1]]).toarray()
array([[ 1., 0., 0., 1., 0., 0., 1., 0., 0.]])

cfehring/slack-onnow | slack-onnow.py | 1 | 6863 | '''
This function handles a Slack slash command named "/onnow" and echoes the details back to the Slack user.
Follow these steps to configure the slash command in Slack:
1. Navigate to https://<your-team-domain>.slack.com/services/new
2. Search for and select "Slash Commands".
3. Enter a name for your command (/onnow) and click "Add Slash Command Integration".
4. Copy the token string from the integration settings and use it in the next section.
5. After you complete this blueprint, enter the provided API endpoint URL in the URL field.
6. Method: POST
7. Customize Name: Pac-12 API
8. Show this command in the autocomplete list (checked)
a. Description: returns live events currently airing on Pac-12.com
b. Usage hint: abbreviate networks: n a b l m o w
Follow these steps to encrypt your Slack token for use in this function:
1. Create a KMS key - http://docs.aws.amazon.com/kms/latest/developerguide/create-keys.html.
2. Encrypt the token using the AWS CLI.
$ aws kms encrypt --key-id alias/<KMS key name> --plaintext "<COMMAND_TOKEN>"
3. Copy the base-64 encoded, encrypted key (CiphertextBlob) to the kmsEncyptedToken variable.
4. Give your function's role permission for the kms:Decrypt action.
Example:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"kms:Decrypt"
],
"Resource": [
"<your KMS key ARN>"
]
}
]
}
Follow these steps to complete the configuration of your command API endpoint
1. When completing the blueprint configuration select "POST" for method and
"Open" for security on the Endpoint Configuration page.
2. After completing the function creation, open the newly created API in the
API Gateway console.
3. Add a mapping template for the application/x-www-form-urlencoded content type with the
following body: { "body": $input.json("$") }
4. Deploy the API to the prod stage.
5. Update the URL for your Slack slash command with the invocation URL for the
created API resource in the prod stage.

#
# Initial code by Andrew Chapman (amchapman@gmail.com), 16th Jan 2014
#
# some logging oddities noticed while doing this, to be followed up on:
# - tradheli MOT labels Mot1,Mot2,Mot3,Mot4,GGain
# - Pixhawk doesn't output one of the FMT labels... forget which one
# - MAG offsets seem to be constant (only seen data on Pixhawk)
# - MAG offsets seem to be cast to int before being output? (param is -84.67, logged as -84)
# - copter+plane use 'V' in their vehicle type/version/build line, rover uses lower case 'v'. Copter+Rover give a build number, plane does not
# - CTUN.ThrOut on copter is 0-1000, on plane+rover it is 0-100
# TODO: add test for noisy baro values
# TODO: support loading binary log files (use Tridge's mavlogdump?)

Constructs an Inception v2 network from inputs to the given final endpoint.
This method can construct the network up to the layer inception(5b) as
described in http://arxiv.org/abs/1502.03167.
Args:
inputs: a tensor of shape [batch_size, height, width, channels].
final_endpoint: specifies the endpoint to construct the network up to. It
can be one of ['Conv2d_1a_7x7', 'MaxPool_2a_3x3', 'Conv2d_2b_1x1',

min_depth: Minimum depth value (number of channels) for all convolution ops.
Enforced when depth_multiplier < 1, and not an active constraint when
depth_multiplier >= 1.
depth_multiplier: Float multiplier for the depth (number of channels)
for all convolution ops. The value must be greater than zero. Typical
usage will be to set this value in (0, 1) to reduce the number of
parameters or computation cost of the model.
scope: Optional variable_scope.
Returns:
tensor_out: output tensor corresponding to the final_endpoint.

losses.
Raises:
ValueError: if final_endpoint is not set to one of the predefined values,
or depth_multiplier <= 0

"""Inception v2 model for classification.
Constructs an Inception v2 network for classification as described in
http://arxiv.org/abs/1502.03167.
The recommended image size used to train this network is 224x224. For image
sizes that differ substantially, it is recommended to use inception_v2_base()
and connect custom final layers to the output.
Args:
inputs: a tensor of shape [batch_size, height, width, channels].
num_classes: number of predicted classes.
is_training: whether is training or not.
dropout_keep_prob: the percentage of activation values that are retained.
min_depth: Minimum depth value (number of channels) for all convolution ops.
Enforced when depth_multiplier < 1, and not an active constraint when
depth_multiplier >= 1.
depth_multiplier: Float multiplier for the depth (number of channels)
for all convolution ops. The value must be greater than zero. Typical
usage will be to set this value in (0, 1) to reduce the number of
parameters or computation cost of the model.
prediction_fn: a function to get predictions out of logits.
spatial_squeeze: if True, logits is of shape [B, C], if false logits is
of shape [B, 1, 1, C], where B is batch_size and C is number of classes.
Note that input image sizes other than 224x224 might lead to different
spatial dimensions, and hence cannot be squeezed. In this event,
it is best to set spatial_squeeze as False, and perform a reduce_mean
over the resulting spatial dimensions with sizes exceeding 1.
reuse: whether or not the network and its variables should be reused. To be
able to reuse 'scope' must be given.
scope: Optional variable_scope.
Returns:
logits: the pre-softmax activations, a tensor of size
[batch_size, num_classes]
end_points: a dictionary from components of the network to the corresponding
activation.
Raises:
ValueError: if depth_multiplier <= 0.

#
# BAW: According to
#http://home.netscape.com/eng/mozilla/2.0/relnotes/demo/content-length.html
# the only portable, reliable way to find message delimiters in a BSD (i.e
# Unix mailbox) style folder is to search for "\n\nFrom .*\n", or at the
# beginning of the file, "^From .*\n". While _fromlinepattern below seems
# like a good idea, in practice, there are too many variations for more
# strict parsing of the line to be completely accurate.
#
# _strict_isrealfromline() is the old version which tries to do stricter
# parsing of the From_ line. _portable_isrealfromline() simply returns
# true, since it's never called if the line doesn't already start with
# "From ".
#
# This algorithm, and the way it interacts with _search_start() and
# _search_end() may not be completely correct, because it doesn't check
# that the two characters preceding "From " are \n\n or the beginning of
# the file. Fixing this would require a more extensive rewrite than is
# necessary. For convenience, we've added a PortableUnixMailbox class
# which does no checking of the format of the 'From' line.

TensorFlow's public C++ API includes only the API for executing graphs, as of
version 0.5. To control the execution of a graph from C++:
1. Build the computation graph using the [Python API](../python/).
1. Use [`tf.train.write_graph()`](../python/train.md#write_graph) to
write the graph to a file.
1. Load the graph using the C++ Session API. For example:
```c++
// Reads a model graph definition from disk, and creates a session object you
// can use to run it.
Status LoadGraph(string graph_file_name, Session** session) {
GraphDef graph_def;
TF_RETURN_IF_ERROR(
ReadBinaryProto(Env::Default(), graph_file_name, &graph_def));
TF_RETURN_IF_ERROR(NewSession(SessionOptions(), session));
TF_RETURN_IF_ERROR((*session)->Create(graph_def));
return Status::OK();
}
```
1. Run the graph with a call to `session->Run()`

This Chart of account is a minimal proposal to be able to use OoB the
accounting feature of Openerp.
This doesn't pretend be all the localization for MX it is just the minimal
data required to start from 0 in mexican localization.
This modules and its content is updated frequently by openerp-mexico team.
With this module you will have:
- Minimal chart of account tested in production eviroments.
- Minimal chart of taxes, to comply with SAT_ requirements.

Simplex representation
======================
The simplices (triangles, tetrahedra, ...) appearing in the Delaunay
tesselation (N-dim simplices), convex hull facets, and Voronoi ridges
(N-1 dim simplices) are represented in the following scheme::
tess = Delaunay(points)
hull = ConvexHull(points)
voro = Voronoi(points)
# coordinates of the j-th vertex of the i-th simplex
tess.points[tess.simplices[i, j], :] # tesselation element
hull.points[hull.simplices[i, j], :] # convex hull facet
voro.vertices[voro.ridge_vertices[i, j], :] # ridge between Voronoi cells
For Delaunay triangulations and convex hulls, the neighborhood
structure of the simplices satisfies the condition:
``tess.neighbors[i,j]`` is the neighboring simplex of the i-th
simplex, opposite to the j-vertex. It is -1 in case of no
neighbor.
Convex hull facets also define a hyperplane equation::
(hull.equations[i,:-1] * coord).sum() + hull.equations[i,-1] == 0
Similar hyperplane equations for the Delaunay triangulation correspond
to the convex hull facets on the corresponding N+1 dimensional
paraboloid.
The Delaunay triangulation objects offer a method for locating the
simplex containing a given point, and barycentric coordinate
computations.

"""Code for encoding protocol message primitives.
Contains the logic for encoding every logical protocol field type
into one of the 5 physical wire types.
This code is designed to push the Python interpreter's performance to the
limits.
The basic idea is that at startup time, for every field (i.e. every
FieldDescriptor) we construct two functions: a "sizer" and an "encoder". The
sizer takes a value of this field's type and computes its byte size. The
encoder takes a writer function and a value. It encodes the value into byte
strings and invokes the writer function to write those strings. Typically the
writer function is the write() method of a cStringIO.
We try to do as much work as possible when constructing the writer and the
sizer rather than when calling them. In particular:
* We copy any needed global functions to local variables, so that we do not need
to do costly global table lookups at runtime.
* Similarly, we try to do any attribute lookups at startup time if possible.
* Every field's tag is encoded to bytes at startup, since it can't change at
runtime.
* Whatever component of the field size we can compute at startup, we do.
* We *avoid* sharing code if doing so would make the code slower and not sharing
does not burden us too much. For example, encoders for repeated fields do
not just call the encoders for singular fields in a loop because this would
add an extra function call overhead for every loop iteration; instead, we
manually inline the single-value encoder into the loop.
* If a Python function lacks a return statement, Python actually generates
instructions to pop the result of the last statement off the stack, push
None onto the stack, and then return that. If we really don't care what
value is returned, then we can save two instructions by returning the
result of the last statement. It looks funny but it helps.
* We assume that type and bounds checking has happened at a higher level.

Notes on Gradient Boosting vs. TreeBoost:
- This implementation is for Stochastic Gradient Boosting, not for TreeBoost.
- Both algorithms learn tree ensembles by minimizing loss functions.
- TreeBoost (Friedman, 1999) additionally modifies the outputs at tree leaf nodes
based on the loss function, whereas the original gradient boosting method does not.
- We expect to implement TreeBoost in the future:

"""Plotting a `Spectrogram` of the Rayleigh statistic
As described in :ref:`gwpy-example-frequencyseries-rayleigh`, the Rayleigh
statistic can be used to study non-Gaussianity in a timeseries.
We can study the time variance of these features by plotting a
time-frequency spectrogram where we calculate the Rayleigh statistic for
each time bin.

module: bigip_gtm_datacenter
short_description: Manage Datacenter configuration in BIG-IP
description:
- Manage BIG-IP data center configuration. A data center defines the location
where the physical network components reside, such as the server and link
objects that share the same subnet on the network. This module is able to
manipulate the data center definitions in a BIG-IP
version_added: "2.2"
options:
contact:
description:
- The name of the contact for the data center.
description:
description:
- The description of the data center.
enabled:
description:
- Whether the data center should be enabled. At least one of C(state) and
C(enabled) are required.
choices:
- yes
- no
location:
description:
- The location of the data center.
name:
description:
- The name of the data center.
required: true
state:
description:
- The state of the datacenter on the BIG-IP. When C(present), guarantees
that the data center exists. When C(absent) removes the data center
from the BIG-IP. C(enabled) will enable the data center and C(disabled)
will ensure the data center is disabled. At least one of state and
enabled are required.
choices:
- present
- absent
notes:
- Requires the f5-sdk Python package on the host. This is as easy as
pip install f5-sdk.
extends_documentation_fragment: f5
requirements:
- f5-sdk

Initialize an ActiveSpaceSolver object
Parameters
----------
input_nodes: Solver
The solver that will provide the molecular orbitals
states: StateInfo, or list(StateInfo), or dict[StateInfo,int], or dict[StateInfo,list(float)]
The state(s) to be computed passed in one of the following ways:
1. A single state
2. A list of single states (will compute one level for each type of state)
3. A dictionary that maps StateInfo objects to the number of states to compute
4. A dictionary that maps StateInfo objects to a list of weights for the states to compute
If explicit weights are passed, these are used in procedures that average properties
over states (e.g., state-averaged CASSCF)
type: {'FCI','ACI','CAS','DETCI','ASCI','PCI'}
The type of solver
mo_spaces: dict[str,list(int)]
A dictionary that specifies the number of MOs per irrep that belong to a given orbital space.
The available spaces are: frozen_docc, restricted_docc, active, restricted_uocc, frozen_uocc, and gas1-gas6.
Please consult the manual for the meaning of these orbital spaces.
A convenience function is provided by the Input class [mo_spaces()] to facilitate the creation of this dict.
Note that an empty dict implies that all orbitals are treated as active.
e_convergence: float
energy convergence criterion
r_convergence: float
residual convergence criterion
options: dict()
Additional options passed to control the active space solver

A callback object used to inject code into the HF class

"""
Format tokens with BBcodes. These formatting codes are used by many
bulletin boards, so you can highlight your sourcecode with pygments before
posting it there.
This formatter has no support for background colors and borders, as there
are no common BBcode tags for that.
Some board systems (e.g. phpBB) don't support colors in their [code] tag,
so you can't use the highlighting together with that tag.
Text in a [code] tag usually is shown with a monospace font (which this
formatter can do with the ``monofont`` option) and no spaces (which you
need for indentation) are removed.
Additional options accepted:
`style`
The style to use, can be a string or a Style subclass (default:
``'default'``).
`codetag`
If set to true, put the output into ``[code]`` tags (default:
``false``)
`monofont`
If set to true, add a tag to show the code with a monospace font
(default: ``false``).
