Package resource API
--------------------
A resource is a logical file contained within a package, or a logical
subdirectory thereof. The package resource API expects resource names
to have their path parts separated with ``/``, *not* whatever the local
path separator is. Do not use os.path operations to manipulate resource
names being passed into the API.
The package resource API is designed to work with normal filesystem packages,
.egg files, and unpacked .egg files. It can also work in a limited way with
.zip files and with custom PEP 302 loaders that support the ``get_data()``
method.

This is a rough cross between distutils' StrictVersion and LooseVersion;
if you give it versions that would work with StrictVersion, then it behaves
the same; otherwise it acts like a slightly-smarter LooseVersion. It is
*possible* to create pathological version coding schemes that will fool
this parser, but they should be very rare in practice.
The returned value will be a tuple of strings. Numeric portions of the
version are padded to 8 digits so they will compare numerically, but
without relying on how numbers compare relative to strings. Dots are
dropped, but dashes are retained. Trailing zeros between alpha segments
or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
"2.4". Alphanumeric parts are lower-cased.
The algorithm assumes that strings like "-" and any alpha string that
alphabetically follows "final" represents a "patch level". So, "2.4-1"
is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
considered newer than "2.4-1", which in turn is newer than "2.4".
Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
come before "final" alphabetically) are assumed to be pre-release versions,
so that the version "2.4" is considered newer than "2.4a1".
Finally, to handle miscellaneous cases, the strings "pre", "preview", and
"rc" are treated as if they were "c", i.e. as though they were release
candidates, and therefore are not as new as a version string that does not
contain them, and "dev" is replaced with an '@' so that it sorts lower than
than any other pre-release tag.

Agglomerative clustering with different metrics
===============================================
Demonstrates the effect of different metrics on the hierarchical clustering.
The example is engineered to show the effect of the choice of different
metrics. It is applied to waveforms, which can be seen as
high-dimensional vector. Indeed, the difference between metrics is
usually more pronounced in high dimension (in particular for euclidean
and cityblock).
We generate data from three groups of waveforms. Two of the waveforms
(waveform 1 and waveform 2) are proportional one to the other. The cosine
distance is invariant to a scaling of the data, as a result, it cannot
distinguish these two waveforms. Thus even with no noise, clustering
using this distance will not separate out waveform 1 and 2.
We add observation noise to these waveforms. We generate very sparse
noise: only 6% of the time points contain noise. As a result, the
l1 norm of this noise (ie "cityblock" distance) is much smaller than it's
l2 norm ("euclidean" distance). This can be seen on the inter-class
distance matrices: the values on the diagonal, that characterize the
spread of the class, are much bigger for the Euclidean distance than for
the cityblock distance.
When we apply clustering to the data, we find that the clustering
reflects what was in the distance matrices. Indeed, for the Euclidean
distance, the classes are ill-separated because of the noise, and thus
the clustering does not separate the waveforms. For the cityblock
distance, the separation is good and the waveform classes are recovered.
Finally, the cosine distance does not separate at all waveform 1 and 2,
thus the clustering puts them in the same cluster.

on first column and file paths on the second column:
.. code::
0,file1.png
1,file2.png
Image file paths are relative to current directory (``os.getcwd()``). The
images need not be square and can be in any format recognized by the
``Image`` module. Internally, the images are converted to RGB and are made
square for you.
Use it in a .yaml file like so:
.. code::
dataset: &trndataset !obj:pyl2extra.datasets.images.Images {
source: 'train.csv',
image_size: 128
}
The ``image_size`` can be skipped, in which case the size of the images is
derived from first image that is provided.
By default the class assumes a classification problem (targets are integers).
If you need to uset it in a regression problem create it like so:
.. code::
dataset: &trndataset !obj:pyl2extra.datasets.images.Images {
source: 'train.csv',
image_size: 128,
regression: True
}
As the dataset simply wraps the ``DenseDesignMatrix``, parameters like
``rng`` (random number generator), ``preprocessor`` and ``fit_preprocessor``
can be used and will be passed to ``DenseDesignMatrix`` superclass.

"""
A pylearn2 dataset that loads the images from a list or csv file.
Please note that - if you use this dataset and your model has a
final Softmax layer you should construct it like so (YAML syntax):
.. code::
!obj:pylearn2.models.mlp.Softmax {
layer_name: 'y',
irange: .0,
n_classes: %(classes)d,
binary_target_dim: 1
}
where ``classes`` is the same number of classes passed to ``Images``
constructor. ``binary_target_dim`` is important and failing to set it
constructs the wrong architecture, causing errors like:
ValueError: VectorSpace(dim=1, dtype=float32) with total dimension 1
can't format a batch into VectorSpace(dim=X, dtype=float32) because
its total dimension is X.
Parameters
----------
source: OrderedDict, dict, str, tuple, list
This argument provides the input images and (optionally)
associated categories. The meaning of the argument depends
on the data type:
- if ``source`` is a string, it is interpreted to be the
path towards a csv file; the file must NOT have a header,
first column must contain the targets (classes or values) and
second column must contain the paths for the image files;
- if ``source`` is a dictionary, the keys must be the
paths for image files, ``Image`` instances or numpy arrays and
the values must be the classes or values (None or empty
string if this instance does not provide the labels);
- a tuple or list must have exactly one or two
members: first one must be a list or tuple of image paths or
Images or numpy arrays, while second one (optional)
has the targets (classes as integers or real values).
image_size: int, optional
The size of the images in the final dataset. All images
will be resized to be ``image_size`` x ``image_size``
pixels.
classes: int, optional
If this is a classification problem the parameter should be
used to indicate the total number of classes and targets are
expected to be integers in the range ``[0; classes-1]``.
If this is a regression problem the parameter should be ``None`` and
targets are expected to be real numbers.
rng: object, optional
A random number generator used for picking random \
indices into the design matrix when choosing minibatches.
preprocessor: Preprocessor, optional
Preprocessor to apply to images.
fit_preprocessor: bool, optional
Whether preprocessor can fit parameters when applied to training
data.

This module is used by the encodings package search function to
map encodings names to module names.
Note that the search function normalizes the encoding names before
doing the lookup, so the mapping will have to map normalized
encoding names to module names.
Contents:
The following aliases dictionary contains mappings of all IANA
character set names for which the Python core library provides
codecs. In addition to these, a few Python specific codec
aliases have also been added.

This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_env_add to provide a more
Python-friendly API
Overview (from the spec)
New texture environment function ADD is supported with the following
equation:
Cv = min(1, Cf + Ct)
New function may be specified by calling TexEnv with ADD token.
One possible application is to add a specular highlight texture to
a Gouraud-shaded primitive to emulate Phong shading, in a single
pass.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/texture_env_add.txt

introspect the data. With 0.4 this can also be forced for requests
that did not fail and outside of `DEBUG` mode. By setting
``'flask._preserve_context'`` to `True` on the WSGI environment the
context will not pop itself at the end of the request. This is used by
the :meth:`~flask.Flask.test_client` for example to implement the
deferred cleanup functionality.
You might find this helpful for unittests where you need the
information from the context local around for a little longer. Make
sure to properly :meth:`~werkzeug.LocalStack.pop` the stack yourself in
that situation, otherwise your unittests will leak memory.

==================================================
Plot different SVM classifiers in the iris dataset
==================================================
Comparison of different linear SVM classifiers on a 2D projection of the iris
dataset. We only consider the first 2 features of this dataset:
- Sepal length
- Sepal width
This example shows how to plot the decision surface for four SVM classifiers
with different kernels.
The linear models ``LinearSVC()`` and ``SVC(kernel='linear')`` yield slightly
different decision boundaries. This can be a consequence of the following
differences:
- ``LinearSVC`` minimizes the squared hinge loss while ``SVC`` minimizes the
regular hinge loss.
- ``LinearSVC`` uses the One-vs-All (also known as One-vs-Rest) multiclass
reduction while ``SVC`` uses the One-vs-One multiclass reduction.
Both linear models have linear decision boundaries (intersecting hyperplanes)
while the non-linear kernel models (polynomial or Gaussian RBF) have more
flexible non-linear decision boundaries with shapes that depend on the kind of
kernel and its parameters.
.. NOTE:: while plotting the decision function of classifiers for toy 2D
datasets can help get an intuitive understanding of their respective
expressive power, be aware that those intuitions don't always generalize to
more realistic high-dimensional problems.

"""
Create a new `Mock` object. `Mock` takes several optional arguments
that specify the behaviour of the Mock object:
* `spec`: This can be either a list of strings or an existing object (a
class or instance) that acts as the specification for the mock object. If
you pass in an object then a list of strings is formed by calling dir on
the object (excluding unsupported magic attributes and methods). Accessing
any attribute not in this list will raise an `AttributeError`.
If `spec` is an object (rather than a list of strings) then
`mock.__class__` returns the class of the spec object. This allows mocks
to pass `isinstance` tests.
* `spec_set`: A stricter variant of `spec`. If used, attempting to *set*
or get an attribute on the mock that isn't on the object passed as
`spec_set` will raise an `AttributeError`.
* `side_effect`: A function to be called whenever the Mock is called. See
the `side_effect` attribute. Useful for raising exceptions or
dynamically changing return values. The function is called with the same
arguments as the mock, and unless it returns `DEFAULT`, the return
value of this function is used as the return value.
If `side_effect` is an iterable then each call to the mock will return
the next value from the iterable. If any of the members of the iterable
are exceptions they will be raised instead of returned.
* `return_value`: The value returned when the mock is called. By default
this is a new Mock (created on first access). See the
`return_value` attribute.
* `wraps`: Item for the mock object to wrap. If `wraps` is not None then
calling the Mock will pass the call through to the wrapped object
(returning the real result). Attribute access on the mock will return a
Mock object that wraps the corresponding attribute of the wrapped object
(so attempting to access an attribute that doesn't exist will raise an
`AttributeError`).
If the mock has an explicit `return_value` set then calls are not passed
to the wrapped object and the `return_value` is returned instead.
* `name`: If the mock has a name then it will be used in the repr of the
mock. This can be useful for debugging. The name is propagated to child
mocks.
Mocks can also be called with arbitrary keyword arguments. These will be
used to set attributes on the mock after it is created.

"""
`patch` acts as a function decorator, class decorator or a context
manager. Inside the body of the function or with statement, the `target`
is patched with a `new` object. When the function/with statement exits
the patch is undone.
If `new` is omitted, then the target is replaced with a
`MagicMock`. If `patch` is used as a decorator and `new` is
omitted, the created mock is passed in as an extra argument to the
decorated function. If `patch` is used as a context manager the created
mock is returned by the context manager.
`target` should be a string in the form `'package.module.ClassName'`. The
`target` is imported and the specified object replaced with the `new`
object, so the `target` must be importable from the environment you are
calling `patch` from. The target is imported when the decorated function
is executed, not at decoration time.
The `spec` and `spec_set` keyword arguments are passed to the `MagicMock`
if patch is creating one for you.
In addition you can pass `spec=True` or `spec_set=True`, which causes
patch to pass in the object being mocked as the spec/spec_set object.
`new_callable` allows you to specify a different class, or callable object,
that will be called to create the `new` object. By default `MagicMock` is
used.
A more powerful form of `spec` is `autospec`. If you set `autospec=True`
then the mock with be created with a spec from the object being replaced.
All attributes of the mock will also have the spec of the corresponding
attribute of the object being replaced. Methods and functions being
mocked will have their arguments checked and will raise a `TypeError` if
they are called with the wrong signature. For mocks replacing a class,
their return value (the 'instance') will have the same spec as the class.
Instead of `autospec=True` you can pass `autospec=some_object` to use an
arbitrary object as the spec instead of the one being replaced.
By default `patch` will fail to replace attributes that don't exist. If
you pass in `create=True`, and the attribute doesn't exist, patch will
create the attribute for you when the patched function is called, and
delete it again afterwards. This is useful for writing tests against
attributes that your production code creates at runtime. It is off by
default because it can be dangerous. With it switched on you can write
passing tests against APIs that don't actually exist!
Patch can be used as a `TestCase` class decorator. It works by
decorating each test method in the class. This reduces the boilerplate
code when your test methods share a common patchings set. `patch` finds
tests by looking for method names that start with `patch.TEST_PREFIX`.
By default this is `test`, which matches the way `unittest` finds tests.
You can specify an alternative prefix by setting `patch.TEST_PREFIX`.
Patch can be used as a context manager, with the with statement. Here the
patching applies to the indented block after the with statement. If you
use "as" then the patched object will be bound to the name after the
"as"; very useful if `patch` is creating a mock object for you.
`patch` takes arbitrary keyword arguments. These will be passed to
the `Mock` (or `new_callable`) on construction.
`patch.dict(...)`, `patch.multiple(...)` and `patch.object(...)` are
available for alternate use-cases.

This module contains helper functions for controlling caching. It does so by
managing the "Vary" header of responses. It includes functions to patch the
header of response objects directly and decorators that change functions to do
that header-patching themselves.
For information on the Vary header, see:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.44
Essentially, the "Vary" HTTP header defines which headers a cache should take
into account when building its cache key. Requests with the same path but
different header content for headers named in "Vary" need to get different
cache keys to prevent delivery of wrong content.
An example: i18n middleware would need to distinguish caches by the
"Accept-language" header.

A dictionary which represents an assignment of values to variables.
An assigment can only assign values from its domain.
If an unknown expression *a* is passed to a model *M*\ 's
interpretation function *i*, *i* will first check whether *M*\ 's
valuation assigns an interpretation to *a* as a constant, and if
this fails, *i* will delegate the interpretation of *a* to
*g*. *g* only assigns values to individual variables (i.e.,
members of the class ``IndividualVariableExpression`` in the ``logic``
module. If a variable is not assigned a value by *g*, it will raise
an ``Undefined`` exception.
A variable *Assignment* is a mapping from individual variables to
entities in the domain. Individual variables are usually indicated
with the letters ``'x'``, ``'y'``, ``'w'`` and ``'z'``, optionally
followed by an integer (e.g., ``'x0'``, ``'y332'``). Assignments are
created using the ``Assignment`` constructor, which also takes the
domain as a parameter.
>>> from nltk.sem.evaluate import Assignment
>>> dom = set(['u1', 'u2', 'u3', 'u4'])
>>> g3 = Assignment(dom, [('x', 'u1'), ('y', 'u2')])
>>> g3
{'y': 'u2', 'x': 'u1'}
There is also a ``print`` format for assignments which uses a notation
closer to that in logic textbooks:
>>> print g3
g[u2/y][u1/x]
It is also possible to update an assignment using the ``add`` method:
>>> dom = set(['u1', 'u2', 'u3', 'u4'])
>>> g4 = Assignment(dom)
>>> g4.add('x', 'u1')
{'x': 'u1'}
With no arguments, ``purge()`` is equivalent to ``clear()`` on a dictionary:
>>> g4.purge()
>>> g4
