"""Pure python implementation of the binary Tokyo Tyrant 1.1.17 protocol
Tokyo Cabinet <http://tokyocabinet.sourceforge.net/> is a "super hyper ultra
database manager" written and maintained by Mikio Hirabayashi and released
under the LGPL.
Tokyo Tyrant is the de facto database server for Tokyo Cabinet written and
maintained by the same author. It supports a REST HTTP protocol, memcached,
and its own simple binary protocol. This library implements the full binary
protocol for the Tokyo Tyrant 1.1.17 in pure Python as defined here::
http://tokyocabinet.sourceforge.net/tyrantdoc/
Typical usage is with the PyTyrant class which provides a dict-like wrapper
for the raw Tyrant protocol::
>>> import pytyrant
>>> t = pytyrant.PyTyrant.open('127.0.0.1', 1978)
>>> t['__test_key__'] = 'foo'
>>> t.concat('__test_key__', 'bar')
>>> print t['__test_key__']
foobar
>>> del t['__test_key__']
Or even:
>>> from pytyrant import open_tyrant
>>> t = open_tyrant() # using default settings; you can specify other
>>> t.__class__
<class 'pytyrant.PyTableTyrant'>
>>> t.search.filter(name__in=['John','Mary'])
['john_doe', 'mary_doh']
(In the latter case the server reported that its database type is TDB, so
the extended version of PyTyrant was automatically chosen.)

Converts a given System of Equations into Matrix form.
Here `equations` must be a linear system of equations in

is returned.
All Standard input formats are supported:
For the given set of Equations, the respective input types
are given below:

`system = (A, b)`
Symbols to solve for should be given as input in all the
cases either in an iterable or as comma separated arguments.
This is done to maintain consistency in returning solutions
in the form of variable input by the user.
The algorithm used here is Gauss-Jordan elimination, which
results, after elimination, in an row echelon form matrix.
Returns
=======
A FiniteSet of ordered tuple of values of `symbols` for which
the `system` has solution.
Please note that general FiniteSet is unordered, the solution
returned here is not simply a FiniteSet of solutions, rather
it is a FiniteSet of ordered tuple, i.e. the first & only
argument to FiniteSet is a tuple of solutions, which is ordered,
& hence the returned solution is ordered.
Also note that solution could also have been returned as an
ordered tuple, FiniteSet is just a wrapper `{}` around
the tuple. It has no other significance except for
the fact it is just used to maintain a consistent output
format throughout the solveset.
Returns EmptySet(), if the linear system is inconsistent.
Raises
======
ValueError
The input is not valid.
The symbols are not given.

job_name: Name of the TensorFlow job the TPUs belong to.
coordinator_name: The name to use for the coordinator. Set to None if the

service: The GCE API object returned by the googleapiclient.discovery
function. If you specify a custom service object, then the credentials
parameter will be ignored.
discovery_url: A URL template that points to the location of
the discovery service. It should have two parameters {api} and

1.0 - Initial version.
1.1 - Adds clone volume option to create_volume.
1.2 - Add publish_service_capabilities() method.
1.3 - Pass all image metadata (not just ID) in copy_volume_to_image.
1.4 - Add request_spec, filter_properties and
allow_reschedule arguments to create_volume().
1.5 - Add accept_transfer.
1.6 - Add extend_volume.
1.7 - Adds host_name parameter to attach_volume()
to allow attaching to host rather than instance.
1.8 - Add migrate_volume, rename_volume.
1.9 - Add new_user and new_project to accept_transfer.
1.10 - Add migrate_volume_completion, remove rename_volume.
1.11 - Adds mode parameter to attach_volume()
to support volume read-only attaching.
1.12 - Adds retype.
1.13 - Adds create_export.
1.14 - Adds reservation parameter to extend_volume().
1.15 - Adds manage_existing and unmanage_only flag to delete_volume.
1.16 - Removes create_export.
1.17 - Add replica option to create_volume, promote_replica and
sync_replica.
1.18 - Adds create_consistencygroup, delete_consistencygroup,
create_cgsnapshot, and delete_cgsnapshot. Also adds
the consistencygroup_id parameter in create_volume.
1.19 - Adds update_migrated_volume
1.20 - Adds support for sending objects over RPC in create_snapshot()
and delete_snapshot()
1.21 - Adds update_consistencygroup.
1.22 - Adds create_consistencygroup_from_src.
1.23 - Adds attachment_id to detach_volume.
1.24 - Removed duplicated parameters: snapshot_id, image_id,
source_volid, source_replicaid, consistencygroup_id and
cgsnapshot_id from create_volume. All off them are already
passed either in request_spec or available in the DB.
1.25 - Add source_cg to create_consistencygroup_from_src.
1.26 - Adds support for sending objects over RPC in
create_consistencygroup(), create_consistencygroup_from_src(),
update_consistencygroup() and delete_consistencygroup().
1.27 - Adds support for replication V2

r""":math:`U`.
Potential energy that the group contributes to the entire system
:math:`[\mathrm{energy}]`.
The potential energy is calculated as a sum of per-particle energy
contributions:
.. math::
U = \sum_{i \in \mathrm{filter}} U_i,
where :math:`U_i` is defined as:
.. math::
U_i = U_{\mathrm{pair}, i} + U_{\mathrm{bond}, i} +
U_{\mathrm{angle}, i} + U_{\mathrm{dihedral}, i} +
U_{\mathrm{improper}, i} + U_{\mathrm{external}, i} +
U_{\mathrm{other}, i}
and each term on the RHS is calculated as:
.. math::
U_{\mathrm{pair}, i} &= \frac{1}{2} \sum_j V_{\mathrm{pair}, ij}
U_{\mathrm{bond}, i} &= \frac{1}{2} \sum_{(j, k) \in
\mathrm{bonds}} V_{\mathrm{bond}, jk}
U_{\mathrm{angle}, i} &= \frac{1}{3} \sum_{(j, k, l) \in
\mathrm{angles}} V_{\mathrm{angle}, jkl}
U_{\mathrm{dihedral}, i} &= \frac{1}{4} \sum_{(j, k, l, m) \in
\mathrm{dihedrals}} V_{\mathrm{dihedral}, jklm}
U_{\mathrm{improper}, i} &= \frac{1}{4} \sum_{(j, k, l, m) \in
\mathrm{impropers}} V_{\mathrm{improper}, jklm}
In each summation above, the indices go over all particles and we only
use terms where one of the summation indices (:math:`j`, :math:`k`,
:math:`l`, or :math:`m`) is equal to :math:`i`. External and other
potentials are summed similar to the other terms using per-particle
contributions.

Args:
filter (``hoomd.filter``): Particle filter to compute thermodynamic
properties for.
kT (float): Temperature of the system :math:`[\\mathrm{energy}]`.
harmonic_pressure (float): Harmonic contribution to the pressure
:math:`[\\mathrm{pressure}]`. If ommitted, the HMA pressure can
still be computed, but will be similar in precision to
the conventional pressure.
:py:class:`HarmonicAveragedThermodynamicQuantities` acts on a given group
of particles and calculates harmonically mapped average (HMA) properties
of those particles when requested. HMA computes properties more precisely
(with less variance) for atomic crystals in NVT simulations. The presence
of diffusion (vacancy hopping, etc.) will prevent HMA from providing
improvement. HMA tracks displacements from the lattice positions, which
are saved either during first call to `Simulation.run` or when the compute
is first added to the simulation, whichever occurs last.
Note:
`HarmonicAveragedThermodynamicQuantities` is an implementation of the
methods section of Sabry G. Moustafa, Andrew J. Schultz, and David A.
Kofke. (2015). "Very fast averaging of thermal properties of crystals
by molecular simulation". Phys. Rev. E 92, 043303

"""Notification Event Converter
The NotificationEventsConverter handles the conversion of Notifications
from openstack systems into Ceilometer Events.
The conversion is handled according to event definitions in a config file.
The config is a list of event definitions. Order is significant, a
notification will be processed according to the LAST definition that
matches it's event_type. (We use the last matching definition because that
allows you to use YAML merge syntax in the definitions file.)
Each definition is a dictionary with the following keys (all are
required):
- event_type: this is a list of notification event_types this definition
will handle. These can be wildcarded with unix shell glob (not regex!)
wildcards.
An exclusion listing (starting with a '!') will exclude any types listed
from matching. If ONLY exclusions are listed, the definition will match
anything not matching the exclusions.
This item can also be a string, which will be taken as equivalent to 1
item list.
Examples:
* ['compute.instance.exists'] will only match
compute.intance.exists notifications
* "compute.instance.exists" Same as above.
* ["image.create", "image.delete"] will match
image.create and image.delete, but not anything else.
* "compute.instance.*" will match
compute.instance.create.start but not image.upload
* ['*.start','*.end', '!scheduler.*'] will match
compute.instance.create.start, and image.delete.end,
but NOT compute.instance.exists or
scheduler.run_instance.start
* '!image.*' matches any notification except image
notifications.
* ['*', '!image.*'] same as above.
- traits: (dict) The keys are trait names, the values are the trait
definitions. Each trait definition is a dictionary with the following
keys:
- type (optional): The data type for this trait. (as a string)
Valid options are: 'text', 'int', 'float' and 'datetime', defaults to
'text' if not specified.
- fields: a path specification for the field(s) in the notification you
wish to extract. The paths can be specified with a dot syntax
(e.g. 'payload.host') or dictionary syntax (e.g. 'payload[host]') is
also supported.
In either case, if the key for the field you are looking for contains
special characters, like '.', it will need to be quoted (with double
or single quotes) like so::
"payload.image_meta.'org.openstack__1__architecture'"
The syntax used for the field specification is a variant of JSONPath,
and is fairly flexible.
(see: https://github.com/kennknowles/python-jsonpath-rw for more info)
Specifications can be written to match multiple possible fields, the
value for the trait will be derived from the matching fields that
exist and have a non-null (i.e. is not None) values in the
notification.
By default the value will be the first such field. (plugins can alter
that, if they wish)
This configuration value is normally a string, for convenience, it can
be specified as a list of specifications, which will be OR'ed together
(a union query in jsonpath terms)
- plugin (optional): (dictionary) with the following keys:
- name: (string) name of a plugin to load
- parameters: (optional) Dictionary of keyword args to pass
to the plugin on initialization. See documentation on each plugin to
see what arguments it accepts.
For convenience, this value can also be specified as a string, which is
interpreted as a plugin name, which will be loaded with no parameters.

"""A helper class for inferring Distribution shape."""
from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
from tensorflow.python.framework import ops
from tensorflow.python.ops import array_ops
class _ShapeUtil(object):
"""Class which helps infer/identify subsets of tensor dimensions.
Terminology:
Recall that a `Tensor` has:
shape: sizes of tensor dimensions,
ndims: size of shape; number of tensor dimensions,
dims: indexes into shape; useful for transpose, reduce.
Tensors sampled from a `Distribution` can be partitioned by:
sample dims: indexes independent, identically distributed (iid) draws,
batch dims: indexes non-identical draws,
event dims: indexes coordinates of a single draw.
The sample, batch, and event dimensions constitute the entirety of a
`Tensor` shape. The dimensions are always in sample, batch, event order.
Assumptions:
We assume that batch_ndims and event_ndims are statically known for both
creating this object and for inputs to its functions.
TODO(jvdillon): Relax this assumption and support fully unknown shape.
We also assume that the `Tensor` rank is static, i.e., `x.get_shape().ndims
is not None`.
Possible use-cases:
~ Sample dimensions:
Computing summary statistics, i.e., the average is a reduction over sample
dimensions.
~ Batch dimensions:
Log-likelihood under model predicted location:
```python
mu = ... # vector of predictions, one for each covariate.
neg_log_likelihood = -tf.reduce_mean(
Normal(loc=mu, scale=1).log_pdf(x),
reduce_dims=[0])
```
Monte Carlo estimation of a marginal probability:
Average over batch dimensions where batch dimensions are associated with
random draws of a prior.
E.g., suppose we want to find the Monte Carlo estimate of the marginal
distribution of a Normal with a random Laplace location:
```
P(X=x) = integral P(X=x|y) P(Y=y) dy
~= 1/n sum_{i=1}^n P(X=x|y_i), y_i ~iid Laplace(0,1)
= tf.reduce_mean(Normal(loc=Laplace(0, 1).sample_n(n=1000),
scale=tf.ones([1000, 1])).pdf(x),
reduce_dims=[0])
```
The `Laplace` distribution generates a tensor of shape [1000, 1]. When fed
to a `Normal`, this is interpreted as 1000 different locations, i.e.,
1000 non-identical Normals. Therefore a single call to pdf(x) yields 1000
probabilities, one for every location. The average over this batch yields
the marginal.
~ Event dimensions:
Computing the determinant of the Jacobian of a function of a random
variable involves a reduction over event dimensions.
Examples:
Write S, B, E for sample shape, batch shape, and event shape (resp.).
```python
x.get_shape() == S + B + E # For statically known x shape.
# 100 iid samples from one multivariate Normal with two
# degrees of freedom (DF).
mu = [0., 0]
sigma = [[1., 0],
[0, 1]]
X = MultivariateNormal(loc=mu, scale=sigma).sample_n(n=100)
# S = [100]
# B = []
# E = [2]
# 100 iid samples from one Wishart with 2x2 DF.
sigma = [[1., 0],
[0, 1]]
X = Wishart(scale=sigma).sample_n(n=100)
# S = [100]
# B = []
# E = [2, 2]
# 100 iid samples (with shape [2, 50]) from two, non-identical bivariate
# Normal distributions.
mu = ... # shape(2, 2)
sigma = ... # shape(2, 2, 2)
X = MultivariateNormal(loc=mu, scale=sigma).sample(shape=[2, 50])
# S = [2, 50]
# B = [2]
# E = [2]
```

# Xcode supports build variable substitutions and CPP; sadly, that doesn't work
# because:
#
# 1. Xcode wants to do the Info.plist work before it runs any build phases,
# this means if we were to generate a .h file for INFOPLIST_PREFIX_HEADER
# we'd have to put it in another target so it runs in time.
# 2. Xcode also doesn't check to see if the header being used as a prefix for
# the Info.plist has changed. So even if we updated it, it's only looking
# at the modtime of the info.plist to see if that's changed.
#
# So, we work around all of this by making a script build phase that will run
# during the app build, and simply update the info.plist in place. This way
# by the time the app target is done, the info.plist is correct.

"""
This sphinx extension adds a tools to simplify generating the API
documentation for Astropy packages and affiliated packages.
.. _automodapi:
========================
automodapi directive
========================
This directive takes a single argument that must be a module or package. It
will produce a block of documentation that includes the docstring for the
package, an :ref:`automodsumm` directive, and an :ref:`automod-diagram` if
there are any classes in the module. If only the main docstring of the
module/package is desired in the documentation, use `automodule`_ instead of
`automodapi`_.
It accepts the following options:
* ``:no-inheritance-diagram:``
If present, the inheritance diagram will not be shown even if
the module/package has classes.
* ``:skip: str``
This option results in the
specified object being skipped, that is the object will *not* be
included in the generated documentation. This option may appear
any number of times to skip multiple objects.
* ``:no-main-docstr:``
If present, the docstring for the module/package will not be generated.
The function and class tables will still be used, however.
* ``:headings: str``
Specifies the characters (in one string) used as the heading
levels used for the generated section. This must have at least 2
characters (any after 2 will be ignored). This also *must* match
the rest of the documentation on this page for sphinx to be
happy. Defaults to "-^", which matches the convention used for
Python's documentation, assuming the automodapi call is inside a
top-level section (which usually uses '=').
* ``:no-heading:``
If specified do not create a top level heading for the section.
That is, do not create a title heading with text like "packagename
Package". The actual docstring for the package/module will still be
shown, though, unless ``:no-main-docstr:`` is given.
* ``:allowed-package-names: str``
Specifies the packages that functions/classes documented here are
allowed to be from, as comma-separated list of package names. If not
given, only objects that are actually in a subpackage of the package
currently being documented are included.
This extension also adds two sphinx configuration options:
* ``automodapi_toctreedirnm``
This must be a string that specifies the name of the directory the
automodsumm generated documentation ends up in. This directory path should
be relative to the documentation root (e.g., same place as ``index.rst``).
Defaults to ``'api'``.
* ``automodapi_writereprocessed``
Should be a bool, and if `True`, will cause `automodapi`_ to write files
with any `automodapi`_ sections replaced with the content Sphinx
processes after `automodapi`_ has run. The output files are not
actually used by sphinx, so this option is only for figuring out the
cause of sphinx warnings or other debugging. Defaults to `False`.
.. _automodule: http://sphinx-doc.org/latest/ext/autodoc.html?highlight=automodule#directive-automodule
"""
# Implementation note:
# The 'automodapi' directive is not actually implemented as a docutils
# directive. Instead, this extension searches for the 'automodapi' text in
# all sphinx documents, and replaces it where necessary from a template built
# into this extension. This is necessary because automodsumm (and autosummary)
# use the "builder-inited" event, which comes before the directives are
# actually built.

"""
Replaces `sourcestr`'s entries of ".. automdapi::" with the
automodapi template form based on provided options.
This is used with the sphinx event 'source-read' to replace
`automodapi`_ entries before sphinx actually processes them, as
automodsumm needs the code to be present to generate stub
documentation.
Parameters
----------
sourcestr : str
The string with sphinx source to be checked for automodapi
replacement.
app : `sphinx.application.Application`
The sphinx application.
dotoctree : bool
If `True`, a ":toctree:" option will be added in the "..
automodsumm::" sections of the template, pointing to the
appropriate "generated" directory based on the Astropy convention
(e.g. in ``docs/api``)
docname : str
The name of the file for this `sourcestr` (if known - if not, it
can be `None`). If not provided and `dotoctree` is `True`, the
generated files may end up in the wrong place.
warnings : bool
If `False`, all warnings that would normally be issued are
silenced.
Returns
-------
newstr :str
The string with automodapi entries replaced with the correct
sphinx markup.

Guidelines for writing new hacking checks
- Use only for Nova specific tests. OpenStack general tests
should be submitted to the common 'hacking' module.
- Pick numbers in the range N3xx. Find the current test with
the highest allocated number and then pick the next value.
- Keep the test method code in the source file ordered based
on the N3xx value.
- List the new rule in the top level HACKING.rst file

The "run name" here is a "frontend run name" - see _run_dir() for the
definition of a "frontend run name" and how it maps to a directory of
profile data for a specific profile "run". The profile plugin concept of
"run" is different from the normal TensorBoard run; each run in this case
represents a single instance of profile data collection, more similar to a
"step" of data in typical TensorBoard semantics. These runs reside in
subdirectories of the plugins/profile directory within any regular
TensorBoard run directory (defined as a subdirectory of the logdir that
contains at least one tfevents file) or within the logdir root directory
itself (even if it contains no tfevents file and would thus not be
considered a normal TensorBoard run, for backwards compatibility).
Within those "profile run directories", there are files in the directory
that correspond to different profiling tools. The file that contains profile
for a specific tool "x" will have a suffix name TOOLS["x"].
Example:
logs/
plugins/
profile/
run1/
hostA.trace
train/
events.out.tfevents.foo
plugins/
profile/
run1/
hostA.trace
hostB.trace
run2/
hostA.trace
validation/
events.out.tfevents.foo
plugins/
profile/
run1/
hostA.trace
Yields:
A sequence of tuples mapping "frontend run names" to lists of tool names
available for those runs. For the above example, this would be:
("run1", ["trace_viewer"])
("train/run1", ["trace_viewer"])
("train/run2", ["trace_viewer"])
("validation/run1", ["trace_viewer"])

Instantiate one of the tokenizer classes of the library from a pretrained model vocabulary.
The tokenizer class to instantiate is selected based on the :obj:`model_type` property of the config object
(either passed as an argument or loaded from :obj:`pretrained_model_name_or_path` if possible), or when it's
missing, by falling back to using pattern matching on :obj:`pretrained_model_name_or_path`:
List options
Params:
pretrained_model_name_or_path (:obj:`str` or :obj:`os.PathLike`):
Can be either:
- A string, the `model id` of a predefined tokenizer hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like ``bert-base-uncased``, or namespaced under
a user or organization name, like ``dbmdz/bert-base-german-cased``.
- A path to a `directory` containing vocabulary files required by the tokenizer, for instance saved
using the :func:`~transformers.PreTrainedTokenizer.save_pretrained` method, e.g.,
``./my_model_directory/``.
- A path or url to a single saved vocabulary file if and only if the tokenizer only requires a
single vocabulary file (like Bert or XLNet), e.g.: ``./my_model_directory/vocab.txt``. (Not
applicable to all derived classes)
inputs (additional positional arguments, `optional`):
Will be passed along to the Tokenizer ``__init__()`` method.
config (:class:`~transformers.PreTrainedConfig`, `optional`)
The configuration object used to dertermine the tokenizer class to instantiate.
cache_dir (:obj:`str` or :obj:`os.PathLike`, `optional`):
Path to a directory in which a downloaded pretrained model configuration should be cached if the
standard cache should not be used.
force_download (:obj:`bool`, `optional`, defaults to :obj:`False`):
Whether or not to force the (re-)download the model weights and configuration files and override the
cached versions if they exist.
resume_download (:obj:`bool`, `optional`, defaults to :obj:`False`):
Whether or not to delete incompletely received files. Will attempt to resume the download if such a
file exists.
proxies (:obj:`Dict[str, str]`, `optional`):
A dictionary of proxy servers to use by protocol or endpoint, e.g., :obj:`{'http': 'foo.bar:3128',
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
revision(:obj:`str`, `optional`, defaults to :obj:`"main"`):
The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a
git-based system for storing models and other artifacts on huggingface.co, so ``revision`` can be any
identifier allowed by git.
subfolder (:obj:`str`, `optional`):
In case the relevant files are located inside a subfolder of the model repo on huggingface.co (e.g. for
facebook/rag-token-base), specify it here.
use_fast (:obj:`bool`, `optional`, defaults to :obj:`True`):
Whether or not to try to load the fast version of the tokenizer.
kwargs (additional keyword arguments, `optional`):
Will be passed to the Tokenizer ``__init__()`` method. Can be used to set special tokens like
``bos_token``, ``eos_token``, ``unk_token``, ``sep_token``, ``pad_token``, ``cls_token``,
``mask_token``, ``additional_special_tokens``. See parameters in the ``__init__()`` for more details.
Examples::
>>> from transformers import AutoTokenizer
>>> # Download vocabulary from huggingface.co and cache.
>>> tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')
>>> # Download vocabulary from huggingface.co (user-uploaded) and cache.
>>> tokenizer = AutoTokenizer.from_pretrained('dbmdz/bert-base-german-cased')
>>> # If vocabulary files are in a directory (e.g. tokenizer was saved using `save_pretrained('./test/saved_model/')`)
