"""Create an attachment.
This method can be used to create an empty attachment (reserve) or to
create and initialize a volume attachment based on the provided input
parameters.
If the caller does not yet have the connector information but needs to
reserve an attachment for the volume (ie Nova BootFromVolume) the
create can be called with just the volume-uuid and the server
identifier. This will reserve an attachment, mark the volume as
reserved and prevent any new attachment_create calls from being made
until the attachment is updated (completed).
The alternative is that the connection can be reserved and initialized
all at once with a single call if the caller has all of the required
information (connector data) at the time of the call.
NOTE: In Nova terms server == instance, the server_id parameter
referenced below is the UUID of the Instance, for non-nova consumers
this can be a server UUID or some other arbitrary unique identifier.

This exports:
- all functions from posix, nt, os2, or ce, e.g. unlink, stat, etc.
- os.path is either posixpath or ntpath
- os.name is either 'posix', 'nt', 'os2' or 'ce'.
- os.curdir is a string representing the current directory ('.' or ':')
- os.pardir is a string representing the parent directory ('..' or '::')
- os.sep is the (or a most common) pathname separator ('/' or ':' or '\\')
- os.extsep is the extension separator (always '.')
- os.altsep is the alternate pathname separator (None or '/')
- os.pathsep is the component separator used in $PATH etc
- os.linesep is the line separator in text files ('\r' or '\n' or '\r\n')
- os.defpath is the default search path for executables
- os.devnull is the file path of the null device ('/dev/null', etc.)
Programs that import and use 'os' stand a better chance of being
portable between different platforms. Of course, they must then
only use functions that are defined by all platforms (e.g., unlink
and opendir), and leave all pathname manipulation to os.path
(e.g., split and join).

# flag doesn't work *either*. Sadly ./configure isn't sophisticated
# enough to detect this condition--it only determines whether or not
# fchmodat() minimally works.
#
# Therefore we simply ignore fchmodat() when deciding whether or not

"""Directory tree generator.
For each directory in the directory tree rooted at top (including top
itself, but excluding '.' and '..'), yields a 3-tuple
dirpath, dirnames, filenames
dirpath is a string, the path to the directory. dirnames is a list of
the names of the subdirectories in dirpath (excluding '.' and '..').
filenames is a list of the names of the non-directory files in dirpath.
Note that the names in the lists are just names, with no path components.
To get a full path (which begins with top) to a file or directory in
dirpath, do os.path.join(dirpath, name).
If optional arg 'topdown' is true or not specified, the triple for a
directory is generated before the triples for any of its subdirectories
(directories are generated top down). If topdown is false, the triple
for a directory is generated after the triples for all of its
subdirectories (directories are generated bottom up).
When topdown is true, the caller can modify the dirnames list in-place
(e.g., via del or slice assignment), and walk will only recurse into the
subdirectories whose names remain in dirnames; this can be used to prune
the search, or to impose a specific order of visiting. Modifying
dirnames when topdown is false is ineffective, since the directories in
dirnames have already been generated by the time dirnames itself is
generated.
By default errors from the os.listdir() call are ignored. If
optional arg 'onerror' is specified, it should be a function; it
will be called with one argument, an os.error instance. It can
report the error to continue with the walk, or raise the exception
to abort the walk. Note that the filename is available as the
filename attribute of the exception object.
By default, os.walk does not follow symbolic links to subdirectories on
systems that support them. In order to get this functionality, set the
optional argument 'followlinks' to true.
Caution: if you pass a relative pathname for top, don't change the
current working directory between resumptions of walk. walk never
changes the current directory, and assumes that the client doesn't
either.
Example:
import os
from os.path import join, getsize
for root, dirs, files in os.walk('python/Lib/email'):
print(root, "consumes", end="")
print(sum([getsize(join(root, name)) for name in files]), end="")

dirpath, dirnames, filenames, dirfd
`dirpath`, `dirnames` and `filenames` are identical to walk() output,
and `dirfd` is a file descriptor referring to the directory `dirpath`.
The advantage of fwalk() over walk() is that it's safe against symlink
races (when follow_symlinks is False).
If dir_fd is not None, it should be a file descriptor open to a directory,
and top should be relative; top will then be relative to that directory.

Since fwalk() yields file descriptors, those are only valid until the
next iteration step, so you should dup() them if you want to keep them

Return a new Lock object using key ``name`` that mimics
the behavior of threading.Lock.
If specified, ``timeout`` indicates a maximum life for the lock.
By default, it will remain locked until release() is called.
``sleep`` indicates the amount of time to sleep per loop iteration
when the lock is in blocking mode and another client is currently
holding the lock.
``blocking_timeout`` indicates the maximum amount of time in seconds to
spend trying to acquire the lock. A value of ``None`` indicates
continue trying forever. ``blocking_timeout`` can be specified as a
float or integer, both representing the number of seconds to wait.
``lock_class`` forces the specified lock implementation.
``thread_local`` indicates whether the lock token is placed in
thread-local storage. By default, the token is placed in thread local
storage so that a thread only sees its token, not a token set by
another thread. Consider the following timeline:
time: 0, thread-1 acquires `my-lock`, with a timeout of 5 seconds.
thread-1 sets the token to "abc"
time: 1, thread-2 blocks trying to acquire `my-lock` using the
Lock instance.
time: 5, thread-1 has not yet completed. redis expires the lock
key.
time: 5, thread-2 acquired `my-lock` now that it's available.
thread-2 sets the token to "xyz"
time: 6, thread-1 finishes its work and calls release(). if the
token is *not* stored in thread local storage, then
thread-1 would see the token value as "xyz" and would be
able to successfully release the thread-2's lock.
In some use cases it's necessary to disable thread local storage. For
example, if you have code where one thread acquires a lock and passes
that lock instance to a worker thread to release later. If thread
local storage isn't disabled in this case, the worker thread won't see
the token set by the thread that acquired the lock. Our assumption
is that these cases aren't common and as such default to using
thread local storage. """

module: yum_repository
author: Jiri Tyr (@jtyr)
version_added: '2.1'
short_description: Add and remove YUM repositories
description:
- Add or remove YUM repositories in RPM-based Linux distributions.
options:
async:
required: false
choices: ['yes', 'no']
default: 'yes'
description:
- If set to C(yes) Yum will download packages and metadata from this
repo in parallel, if possible.
bandwidth:
required: false
default: 0
description:
- Maximum available network bandwidth in bytes/second. Used with the
I(throttle) option.
- If I(throttle) is a percentage and bandwidth is C(0) then bandwidth
throttling will be disabled. If I(throttle) is expressed as a data rate
(bytes/sec) then this option is ignored. Default is C(0) (no bandwidth
throttling).
baseurl:
required: false
default: null
description:
- URL to the directory where the yum repository's 'repodata' directory
lives.
- This or the I(mirrorlist) parameter is required if I(state) is set to
C(present).
cost:
required: false
default: 1000
description:
- Relative cost of accessing this repository. Useful for weighing one
repo's packages as greater/less than any other.
deltarpm_metadata_percentage:
required: false
default: 100
description:
- When the relative size of deltarpm metadata vs pkgs is larger than
this, deltarpm metadata is not downloaded from the repo. Note that you
can give values over C(100), so C(200) means that the metadata is
required to be half the size of the packages. Use C(0) to turn off
this check, and always download metadata.
deltarpm_percentage:
required: false
default: 75
description:
- When the relative size of delta vs pkg is larger than this, delta is
not used. Use C(0) to turn off delta rpm processing. Local repositories
(with file:// I(baseurl)) have delta rpms turned off by default.
description:
required: false
default: null
description:
- A human readable string describing the repository.
- This parameter is only required if I(state) is set to C(present).
enabled:
required: false
choices: ['yes', 'no']
default: 'yes'
description:
- This tells yum whether or not use this repository.
enablegroups:
required: false
choices: ['yes', 'no']
default: 'yes'
description:
- Determines whether yum will allow the use of package groups for this
repository.
exclude:
required: false
default: null
description:
- List of packages to exclude from updates or installs. This should be a
space separated list. Shell globs using wildcards (eg. C(*) and C(?))
are allowed.
- The list can also be a regular YAML array.
failovermethod:
required: false
choices: [roundrobin, priority]
default: roundrobin
description:
- C(roundrobin) randomly selects a URL out of the list of URLs to start
with and proceeds through each of them as it encounters a failure
contacting the host.
- C(priority) starts from the first I(baseurl) listed and reads through
them sequentially.
file:
required: false
default: null
description:
- File to use to save the repo in. Defaults to the value of I(name).
gpgcakey:
required: false
default: null
description:
- A URL pointing to the ASCII-armored CA key file for the repository.
gpgcheck:
required: false
choices: ['yes', 'no']
default: 'no'
description:
- Tells yum whether or not it should perform a GPG signature check on
packages.
gpgkey:
required: false
default: null
description:
- A URL pointing to the ASCII-armored GPG key file for the repository.
http_caching:
required: false
choices: [all, packages, none]
default: all
description:
- Determines how upstream HTTP caches are instructed to handle any HTTP
downloads that Yum does.
- C(all) means that all HTTP downloads should be cached.
- C(packages) means that only RPM package downloads should be cached (but
not repository metadata downloads).
- C(none) means that no HTTP downloads should be cached.
include:
required: false
default: null
description:
- Include external configuration file. Both, local path and URL is
supported. Configuration file will be inserted at the position of the
I(include=) line. Included files may contain further include lines.
Yum will abort with an error if an inclusion loop is detected.
includepkgs:
required: false
default: null
description:
- List of packages you want to only use from a repository. This should be
a space separated list. Shell globs using wildcards (eg. C(*) and C(?))
are allowed. Substitution variables (e.g. C($releasever)) are honored
here.
- The list can also be a regular YAML array.
ip_resolve:
required: false
choices: [4, 6, IPv4, IPv6, whatever]
default: whatever
description:
- Determines how yum resolves host names.
- C(4) or C(IPv4) - resolve to IPv4 addresses only.
- C(6) or C(IPv6) - resolve to IPv6 addresses only.
keepalive:
required: false
choices: ['yes', 'no']
default: 'no'
description:
- This tells yum whether or not HTTP/1.1 keepalive should be used with
this repository. This can improve transfer speeds by using one
connection when downloading multiple files from a repository.
keepcache:
required: false
choices: ['0', '1']
default: '1'
description:
- Either C(1) or C(0). Determines whether or not yum keeps the cache of
headers and packages after successful installation.
metadata_expire:
required: false
default: 21600
description:
- Time (in seconds) after which the metadata will expire.
- Default value is 6 hours.
metadata_expire_filter:
required: false
choices: [never, 'read-only:past', 'read-only:present', 'read-only:future']
default: 'read-only:present'
description:
- Filter the I(metadata_expire) time, allowing a trade of speed for
accuracy if a command doesn't require it. Each yum command can specify
that it requires a certain level of timeliness quality from the remote
repos. from "I'm about to install/upgrade, so this better be current"
to "Anything that's available is good enough".
- C(never) - Nothing is filtered, always obey I(metadata_expire).
- C(read-only:past) - Commands that only care about past information are
filtered from metadata expiring. Eg. I(yum history) info (if history
needs to lookup anything about a previous transaction, then by
definition the remote package was available in the past).
- C(read-only:present) - Commands that are balanced between past and
future. Eg. I(yum list yum).
- C(read-only:future) - Commands that are likely to result in running
other commands which will require the latest metadata. Eg.
I(yum check-update).
- Note that this option does not override "yum clean expire-cache".
metalink:
required: false
default: null
description:
- Specifies a URL to a metalink file for the repomd.xml, a list of
mirrors for the entire repository are generated by converting the
mirrors for the repomd.xml file to a I(baseurl).
mirrorlist:
required: false
default: null
description:
- Specifies a URL to a file containing a list of baseurls.
- This or the I(baseurl) parameter is required if I(state) is set to
C(present).
mirrorlist_expire:
required: false
default: 21600
description:
- Time (in seconds) after which the mirrorlist locally cached will
expire.
- Default value is 6 hours.
name:
required: true
description:
- Unique repository ID.
- This parameter is only required if I(state) is set to C(present) or
C(absent).
params:
required: false
default: null
description:
- Option used to allow the user to overwrite any of the other options.
To remove an option, set the value of the option to C(null).
password:
required: false
default: null
description:
- Password to use with the username for basic authentication.
priority:
required: false
default: 99
description:
- Enforce ordered protection of repositories. The value is an integer
from 1 to 99.
- This option only works if the YUM Priorities plugin is installed.
protect:
required: false
choices: ['yes', 'no']
default: 'no'
description:
- Protect packages from updates from other repositories.
proxy:
required: false
default: null
description:
- URL to the proxy server that yum should use.
proxy_password:
required: false
default: null
description:
- Username to use for proxy.

required: false
choices: ['yes', 'no']
default: 'no'
description:
- This tells yum whether or not it should perform a GPG signature check
on the repodata from this repository.
reposdir:
required: false
default: /etc/yum.repos.d
description:
- Directory where the C(.repo) files will be stored.
retries:
required: false
default: 10
description:
- Set the number of times any attempt to retrieve a file should retry
before returning an error. Setting this to C(0) makes yum try forever.
s3_enabled:
required: false
choices: ['yes', 'no']
default: 'no'
description:
- Enables support for S3 repositories.
- This option only works if the YUM S3 plugin is installed.
skip_if_unavailable:
required: false
choices: ['yes', 'no']
default: 'no'
description:
- If set to C(yes) yum will continue running if this repository cannot be
contacted for any reason. This should be set carefully as all repos are
consulted for any given command.
ssl_check_cert_permissions:
required: false
choices: ['yes', 'no']
default: 'no'
description:
- Whether yum should check the permissions on the paths for the
certificates on the repository (both remote and local).
- If we can't read any of the files then yum will force
I(skip_if_unavailable) to be C(yes). This is most useful for non-root
processes which use yum on repos that have client cert files which are
readable only by root.

- Number of seconds to wait for a connection before timing out.
ui_repoid_vars:
required: false
default: releasever basearch
description:
- When a repository id is displayed, append these yum variables to the
string if they are used in the I(baseurl)/etc. Variables are appended
in the order listed (and found).
username:
required: false
default: null
description:
- Username to use for basic authentication to a repo or really any url.
extends_documentation_fragment:

ast
~~~
The `ast` module helps Python applications to process trees of the Python
abstract syntax grammar. The abstract syntax itself might change with
each Python release; this module helps to find out programmatically what
the current grammar looks like and allows modifications of it.
An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
a flag to the `compile()` builtin function or by using the `parse()`
function from this module. The result will be a tree of objects whose
classes all inherit from `ast.AST`.
A modified abstract syntax tree can be compiled into a Python code object
using the built-in `compile()` function.
Additionally various helper functions are provided that make working with
the trees simpler. The main intention of the helper functions and this
module in general is to provide an easy to use interface for libraries
that work tightly with the python syntax (template engines for example).

just a single node.

gilessbrown/wextracto | wex/composed.py | 3 | 4382 | """
Wextracto uses `Function composition <http://en.wikipedia.org/wiki/Function_composition_%28computer_science%29>`_
as an easy way to build new functions from existing ones:
.. code-block:: pycon
>>> from wex.composed import compose
>>> def add1(x):
... return x + 1
...
>>> def mult2(x):
... return x * 2
...
>>> f = compose(add1, mult2)
>>> f(2)
6
Wextracto uses the pipe operator, ``|``, as a shorthand for function composition.
This shorthand can be a powerful technique for reducing boilerplate code when
used in combination with :func:`.named` extractors:
.. code-block:: python
from wex.etree import css, text
from wex.extractor import named
attrs = named(title = css('h1') | text

Format tokens as an SVG graphics file. This formatter is still experimental.
Each line of code is a ``<text>`` element with explicit ``x`` and ``y``
coordinates containing ``<tspan>`` elements with the individual token styles.
By default, this formatter outputs a full SVG document including doctype
declaration and the ``<svg>`` root element.
*New in Pygments 0.9.*
Additional options accepted:
`nowrap`
Don't wrap the SVG ``<text>`` elements in ``<svg><g>`` elements and
don't add a XML declaration and a doctype. If true, the `fontfamily`
and `fontsize` options are ignored. Defaults to ``False``.
`fontfamily`
The value to give the wrapping ``<g>`` element's ``font-family``
attribute, defaults to ``"monospace"``.
`fontsize`
The value to give the wrapping ``<g>`` element's ``font-size``
attribute, defaults to ``"14px"``.
`xoffset`
Starting offset in X direction, defaults to ``0``.
`yoffset`
Starting offset in Y direction, defaults to the font size if it is given
in pixels, or ``20`` else. (This is necessary since text coordinates
refer to the text baseline, not the top edge.)
`ystep`
Offset to add to the Y coordinate for each subsequent line. This should
roughly be the text size plus 5. It defaults to that value if the text
size is given in pixels, or ``25`` else.
`spacehack`
Convert spaces in the source to `` ``, which are non-breaking
spaces. SVG provides the ``xml:space`` attribute to control how
whitespace inside tags is handled, in theory, the ``preserve`` value
could be used to keep all whitespace as-is. However, many current SVG
viewers don't obey that rule, so this option is provided as a workaround
and defaults to ``True``.

# The following import/except block for edxval is temporary measure until
# edxval is a proper XBlock Runtime Service.
#
# Here's the deal: the VideoModule should be able to take advantage of edx-val
# (https://github.com/edx/edx-val) to figure out what URL to give for video
# resources that have an edx_video_id specified. edx-val is a Django app, and
# including it causes tests to fail because we run common/lib tests standalone
# without Django dependencies. The alternatives seem to be:
#
# 1. Move VideoModule out of edx-platform.
# 2. Accept the Django dependency in common/lib.
# 3. Try to import, catch the exception on failure, and check for the existence
# of edxval_api before invoking it in the code.
# 4. Make edxval an XBlock Runtime Service
#
# (1) is a longer term goal. VideoModule should be made into an XBlock and
# extracted from edx-platform entirely. But that's expensive to do because of
# the various dependencies (like templates). Need to sort this out.
# (2) is explicitly discouraged.
# (3) is what we're doing today. The code is still functional when called within
# the context of the LMS, but does not cause failure on import when running
# standalone tests. Most VideoModule tests tend to be in the LMS anyway,
# probably for historical reasons, so we're not making things notably worse.
# (4) is one of the next items on the backlog for edxval, and should get rid
# of this particular import silliness. It's just that I haven't made one before,
# and I was worried about trying it with my deadline constraints.

This toy data set consists of a fixed number (``train_size``) of iid draws

specified by the ``noise_level``.
Args:
batch_size (int): The mini-batch size to use. Note that, if ``batch_size``
is not a divider of the dataset size (``1000`` for train and test) the
remainder is dropped in each epoch (after shuffling).
train_size (int): Size of the training data set. This will also be used as
the train_eval and test set size. Defaults to ``1000``.
noise_level (float): Standard deviation of the data points around the mean.
The data points are drawn from a Gaussian distribution. Defaults to
``1.0``.
Attributes:
batch: A tuple ``(x, y)`` of tensors with random x and y that can be used to
create a noisy two dimensional testproblem. Executing these
tensors raises a ``tf.errors.OutOfRangeError`` after one epoch.
train_init_op: A tensorflow operation initializing the dataset for the
training phase.
train_eval_init_op: A tensorflow operation initializing the testproblem for
evaluating on training data.
test_init_op: A tensorflow operation initializing the testproblem for
evaluating on test data.
phase: A string-value tf.Variable that is set to "train", "train_eval" or
"test", depending on the current phase. This can be used by testproblems
to adapt their behavior to this phase.

# complex to simplify some common cases ("foo" module in "foo.c") and do
# better error-checking ("foo.c" actually exists).

# Also, putting this in build_ext.py means every setup script would have to
# import that large-ish module (indirectly, through distutils.core) in
# order to do anything.
class Extension:
"""Just a collection of attributes that describes an extension
module and everything needed to build it (hopefully in a portable
way, but there are hooks that let you be as unportable as you need).
Instance attributes:
name : string
the full name of the extension, including any packages -- ie.
*not* a filename or pathname, but Python dotted name
sources : [string]
list of source filenames, relative to the distribution root
(where the setup script lives), in Unix form (slash-separated)
for portability. Source files may be C, C++, SWIG (.i),
platform-specific resource files, or whatever else is recognized
by the "build_ext" command as source for a Python extension.
include_dirs : [string]
list of directories to search for C/C++ header files (in Unix
form for portability)
define_macros : [(name : string, value : string|None)]
list of macros to define; each macro is defined using a 2-tuple,
where 'value' is either the string to define it to or None to
define it without a particular value (equivalent of "#define
FOO" in source or -DFOO on Unix C compiler command line)
undef_macros : [string]
list of macros to undefine explicitly
library_dirs : [string]
list of directories to search for C/C++ libraries at link time
libraries : [string]
list of library names (not filenames or paths) to link against
runtime_library_dirs : [string]
list of directories to search for C/C++ libraries at run time
(for shared extensions, this is when the extension is loaded)
extra_objects : [string]
list of extra files to link with (eg. object files not implied
by 'sources', static library that must be explicitly specified,
binary resource files, etc.)
extra_compile_args : [string]
any extra platform- and compiler-specific information to use
when compiling the source files in 'sources'. For platforms and
compilers where "command line" makes sense, this is typically a
list of command-line arguments, but for other platforms it could
be anything.
extra_link_args : [string]
any extra platform- and compiler-specific information to use
when linking object files together to create the extension (or
to create a new static Python interpreter). Similar
interpretation as for 'extra_compile_args'.
export_symbols : [string]
list of symbols to be exported from a shared extension. Not
used on all platforms, and not generally necessary for Python
extensions, which typically export exactly one symbol: "init" +
extension_name.
swig_opts : [string]
any extra options to pass to SWIG if a source file has the .i
extension.
depends : [string]
list of files that the extension depends on
language : string
extension language (i.e. "c", "c++", "objc"). Will be detected
from the source extensions if not provided.

"""
Apply a correspondence defined between two vertex sets to a new set.
Identifies a correspondence between `correspondence_src` and
`correspondence_dst` then applies that correspondence to `vertices`.
That is, `correspondence_src` is to `correspondence_dst` as `vertices` is
to [ return value ].
`correspondence_src` and `vertices` must have the same topology. The return
value will have the same topology as `correspondence_dst`. Arguments can
be passed as `chumpy` or `numpy` arrays.
The most common usecase here is establishing a relationship between an
alignment and a pointcloud or set of landmarks. The pointcloud or landmarks
can then be moved automatically as the alignment is adjusted (e.g. fit to a
different mesh, reposed, etc).
Args:
correspondence_src: The source vertices for the correspondence
correspondence_dst: The destination vertices for the correspondence
vertices: The vertices to map using the defined correspondence
Returns:
the mapped version of `vertices`
Example usage
-------------
>>> transformed_scan_vertices = apply_correspondence(

"""Plot rectangular data as a color-encoded matrix.
This function tries to infer a good colormap to use from the data, but
this is not guaranteed to work, so take care to make sure the kind of
colormap (sequential or diverging) and its limits are appropriate.
This is an Axes-level function and will draw the heatmap into the
currently-active Axes if none is provided to the ``ax`` argument. Part of
this Axes space will be taken and used to plot a colormap, unless ``cbar``
is False or a separate Axes is provided to ``cbar_ax``.
Parameters
----------
data : rectangular dataset
2D dataset that can be coerced into an ndarray. If a Pandas DataFrame
is provided, the index/column information will be used to label the
columns and rows.
vmin, vmax : floats, optional
Values to anchor the colormap, otherwise they are inferred from the
data and other keyword arguments. When a diverging dataset is inferred,
one of these values may be ignored.
cmap : matplotlib colormap name or object, optional
The mapping from data values to color space. If not provided, this
will be either a cubehelix map (if the function infers a sequential
dataset) or ``RdBu_r`` (if the function infers a diverging dataset).
center : float, optional
The value at which to center the colormap. Passing this value implies
use of a diverging colormap.
robust : bool, optional
If True and ``vmin`` or ``vmax`` are absent, the colormap range is
computed with robust quantiles instead of the extreme values.
annot : bool, optional
If True, write the data value in each cell.
fmt : string, optional
String formatting code to use when ``annot`` is True.
annot_kws : dict of key, value mappings, optional
Keyword arguments for ``ax.text`` when ``annot`` is True.
linewidths : float, optional
Width of the lines that will divide each cell.
linecolor : color, optional
Color of the lines that will divide each cell.
cbar : boolean, optional
Whether to draw a colorbar.
cbar_kws : dict of key, value mappings, optional
Keyword arguments for `fig.colorbar`.
cbar_ax : matplotlib Axes, optional
Axes in which to draw the colorbar, otherwise take space from the
main Axes.
square : boolean, optional
If True, set the Axes aspect to "equal" so each cell will be
square-shaped.
ax : matplotlib Axes, optional
Axes in which to draw the plot, otherwise use the currently-active
Axes.
xticklabels : list-like, int, or bool, optional
If True, plot the column names of the dataframe. If False, don't plot
the column names. If list-like, plot these alternate labels as the
xticklabels. If an integer, use the column names but plot only every
n label.
yticklabels : list-like, int, or bool, optional
If True, plot the row names of the dataframe. If False, don't plot
the row names. If list-like, plot these alternate labels as the
yticklabels. If an integer, use the index names but plot only every
n label.
mask : boolean array or DataFrame, optional
If passed, data will not be shown in cells where ``mask`` is True.
Cells with missing values are automatically masked.
kwargs : other keyword arguments
All other keyword arguments are passed to ``ax.pcolormesh``.
Returns
-------
ax : matplotlib Axes
Axes object with the heatmap.
Examples
--------
Plot a heatmap for a numpy array:
.. plot::
:context: close-figs
>>> import numpy as np; np.random.seed(0)
>>> import seaborn as sns; sns.set()
>>> uniform_data = np.random.rand(10, 12)
>>> ax = sns.heatmap(uniform_data)
Change the limits of the colormap:
.. plot::
:context: close-figs
>>> ax = sns.heatmap(uniform_data, vmin=0, vmax=1)
Plot a heatmap for data centered on 0:
.. plot::
:context: close-figs
>>> normal_data = np.random.randn(10, 12)
>>> ax = sns.heatmap(normal_data)
Plot a dataframe with meaningful row and column labels:
.. plot::
:context: close-figs
>>> flights = sns.load_dataset("flights")
>>> flights = flights.pivot("month", "year", "passengers")
>>> ax = sns.heatmap(flights)
Annotate each cell with the numeric value using integer formatting:
.. plot::
:context: close-figs
>>> ax = sns.heatmap(flights, annot=True, fmt="d")
Add lines between each cell:
.. plot::
:context: close-figs
>>> ax = sns.heatmap(flights, linewidths=.5)
Use a different colormap:
.. plot::
:context: close-figs
>>> ax = sns.heatmap(flights, cmap="YlGnBu")
Center the colormap at a specific value:
.. plot::
:context: close-figs
>>> ax = sns.heatmap(flights, center=flights.loc["January", 1955])
Plot every other column label and don't plot row labels:
.. plot::
:context: close-figs
>>> data = np.random.randn(50, 20)
>>> ax = sns.heatmap(data, xticklabels=2, yticklabels=False)
Don't draw a colorbar:
.. plot::
:context: close-figs
>>> ax = sns.heatmap(flights, cbar=False)
Use different axes for the colorbar:
.. plot::
:context: close-figs
>>> grid_kws = {"height_ratios": (.9, .05), "hspace": .3}
>>> f, (ax, cbar_ax) = plt.subplots(2, gridspec_kw=grid_kws)
>>> ax = sns.heatmap(flights, ax=ax,
... cbar_ax=cbar_ax,
... cbar_kws={"orientation": "horizontal"})
Use a mask to plot only part of a matrix
.. plot::
:context: close-figs
>>> corr = np.corrcoef(np.random.randn(10, 200))
>>> mask = np.zeros_like(corr)
>>> mask[np.triu_indices_from(mask)] = True
>>> with sns.axes_style("white"):
... ax = sns.heatmap(corr, mask=mask, vmax=.3, square=True)

Parameters
----------
data: pandas.DataFrame
Rectangular data for clustering. Cannot contain NAs.
pivot_kws : dict, optional
If `data` is a tidy dataframe, can provide keyword arguments for
pivot to create a rectangular dataframe.
method : str, optional
Linkage method to use for calculating clusters.
See scipy.cluster.hierarchy.linkage documentation for more information:
http://docs.scipy.org/doc/scipy/reference/generated/scipy.cluster.hierarchy.linkage.html
metric : str, optional
Distance metric to use for the data. See
scipy.spatial.distance.pdist documentation for more options
http://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.distance.pdist.html
z_score : int or None, optional
Either 0 (rows) or 1 (columns). Whether or not to calculate z-scores
for the rows or the columns. Z scores are: z = (x - mean)/std, so
values in each row (column) will get the mean of the row (column)
subtracted, then divided by the standard deviation of the row (column).
This ensures that each row (column) has mean of 0 and variance of 1.
standard_scale : int or None, optional
Either 0 (rows) or 1 (columns). Whether or not to standardize that
dimension, meaning for each row or column, subtract the minimum and
divide each by its maximum.
figsize: tuple of two ints, optional
Size of the figure to create.
cbar_kws : dict, optional
Keyword arguments to pass to ``cbar_kws`` in ``heatmap``, e.g. to
add a label to the colorbar.
{row,col}_cluster : bool, optional
If True, cluster the {rows, columns}.
{row,col}_linkage : numpy.array, optional
Precomputed linkage matrix for the rows or columns. See
scipy.cluster.hierarchy.linkage for specific formats.
{row,col}_colors : list-like, optional
List of colors to label for either the rows or columns. Useful to
evaluate whether samples within a group are clustered together. Can
use nested lists for multiple color levels of labeling.
mask : boolean array or DataFrame, optional
If passed, data will not be shown in cells where ``mask`` is True.
Cells with missing values are automatically masked. Only used for
visualizing, not for calculating.
kwargs : other keyword arguments
All other keyword arguments are passed to ``sns.heatmap``
Returns
-------
clustergrid : ClusterGrid
A ClusterGrid instance.
Notes
-----
The returned object has a ``savefig`` method that should be used if you
want to save the figure object without clipping the dendrograms.
To access the reordered row indices, use:
``clustergrid.dendrogram_row.reordered_ind``
Column indices, use:

perlcile - a Code Intelligence Language Engine for the Perl language
Module Usage:
from perlcile import scan_purelang
content = open("foo.pl", "r").read()
scan_purelang(content, "foo.pl")
Command-line Usage:
perlcile.py [<options>...] [<Perl file>]
Options:
-h, --help dump this help and exit
-V, --version dump this script's version and exit
-v, --verbose verbose output, use twice for more verbose output
-f, --filename <path> specify the filename of the file content
passed in on stdin, this is used for the "path"
attribute of the emitted <file> tag.
--md5=<string> md5 hash for the input
--mtime=<secs> modification time for output info, in #secs since
1/1/70.
-L, --language <name>
the language of the file being scanned
-c, --clock print timing info for scans (CIX is not printed)
One or more Perl files can be specified as arguments or content can be
passed in on stdin. A directory can also be specified, in which case
all .pl files in that directory are scanned.
This is a Language Engine for the Code Intelligence (codeintel) system.
Code Intelligence XML format. See:
http://specs.activestate.com/Komodo_3.0/func/code_intelligence.html
http://specs.tl.activestate.com/kd/kd-0100.html
The command-line interface will return non-zero iff the scan failed.

"""Generates a `tf.data.Dataset` from image files in a directory.
If your directory structure is:
```
main_directory/
...class_a/
......a_image_1.jpg
......a_image_2.jpg
...class_b/
......b_image_1.jpg
......b_image_2.jpg
```
Then calling `image_dataset_from_directory(main_directory, labels='inferred')`
will return a `tf.data.Dataset` that yields batches of images from
the subdirectories `class_a` and `class_b`, together with labels
0 and 1 (0 corresponding to `class_a` and 1 corresponding to `class_b`).
Supported image formats: jpeg, png, bmp, gif.
Animated gifs are truncated to the first frame.
Args:
directory: Directory where the data is located.
If `labels` is "inferred", it should contain
subdirectories, each containing images for a class.
Otherwise, the directory structure is ignored.
labels: Either "inferred"
(labels are generated from the directory structure),
None (no labels),
or a list/tuple of integer labels of the same size as the number of
image files found in the directory. Labels should be sorted according
to the alphanumeric order of the image file paths
(obtained via `os.walk(directory)` in Python).
label_mode:
- 'int': means that the labels are encoded as integers
(e.g. for `sparse_categorical_crossentropy` loss).
- 'categorical' means that the labels are
encoded as a categorical vector
(e.g. for `categorical_crossentropy` loss).
- 'binary' means that the labels (there can be only 2)
are encoded as `float32` scalars with values 0 or 1
(e.g. for `binary_crossentropy`).
- None (no labels).
class_names: Only valid if "labels" is "inferred". This is the explict
list of class names (must match names of subdirectories). Used
to control the order of the classes
(otherwise alphanumerical order is used).
color_mode: One of "grayscale", "rgb", "rgba". Default: "rgb".
Whether the images will be converted to
have 1, 3, or 4 channels.
batch_size: Size of the batches of data. Default: 32.
image_size: Size to resize images to after they are read from disk.
Defaults to `(256, 256)`.
Since the pipeline processes batches of images that must all have
the same size, this must be provided.
shuffle: Whether to shuffle the data. Default: True.
If set to False, sorts the data in alphanumeric order.
seed: Optional random seed for shuffling and transformations.
validation_split: Optional float between 0 and 1,
fraction of data to reserve for validation.
subset: One of "training" or "validation".
Only used if `validation_split` is set.
interpolation: String, the interpolation method used when resizing images.
Defaults to `bilinear`. Supports `bilinear`, `nearest`, `bicubic`,
`area`, `lanczos3`, `lanczos5`, `gaussian`, `mitchellcubic`.
follow_links: Whether to visits subdirectories pointed to by symlinks.
Defaults to False.
crop_to_aspect_ratio: If True, resize the images without aspect
ratio distortion. When the original aspect ratio differs from the target
aspect ratio, the output image will be cropped so as to return the largest
possible window in the image (of size `image_size`) that matches
the target aspect ratio. By default (`crop_to_aspect_ratio=False`),
aspect ratio may not be preserved.
**kwargs: Legacy keyword arguments.
Returns:
A `tf.data.Dataset` object.
- If `label_mode` is None, it yields `float32` tensors of shape
`(batch_size, image_size[0], image_size[1], num_channels)`,
encoding images (see below for rules regarding `num_channels`).
- Otherwise, it yields a tuple `(images, labels)`, where `images`
has shape `(batch_size, image_size[0], image_size[1], num_channels)`,
and `labels` follows the format described below.
Rules regarding labels format:
- if `label_mode` is `int`, the labels are an `int32` tensor of shape
`(batch_size,)`.
- if `label_mode` is `binary`, the labels are a `float32` tensor of
1s and 0s of shape `(batch_size, 1)`.
- if `label_mode` is `categorial`, the labels are a `float32` tensor
of shape `(batch_size, num_classes)`, representing a one-hot
encoding of the class index.
Rules regarding number of channels in the yielded images:
- if `color_mode` is `grayscale`,
there's 1 channel in the image tensors.
- if `color_mode` is `rgb`,
there are 3 channel in the image tensors.
- if `color_mode` is `rgba`,
there are 4 channel in the image tensors.

``Module`` exists mainly for caching purposes.
Basically :mod:`modules` offers the classes:
- ``CachedModule``, a base class for Cachedmodule.
- ``Module`` the class for all normal Python modules (not builtins, they are at
home at :mod:`builtin`).
- ``ModuleWithCursor``, holds the module information for :class:`api.Script`.
Apart from those classes there's a ``sys.path`` fetching function, as well as
