"""
This module implements a VERY limited parser that finds <link> tags in
the head of HTML or XHTML documents and parses out their attributes
according to the OpenID spec. It is a liberal parser, but it requires
these things from the data in order to work:
- There must be an open <html> tag
- There must be an open <head> tag inside of the <html> tag
- Only <link>s that are found inside of the <head> tag are parsed
(this is by design)
- The parser follows the OpenID specification in resolving the
attributes of the link tags. This means that the attributes DO NOT
get resolved as they would by an XML or HTML parser. In particular,
only certain entities get replaced, and href attributes do not get
resolved relative to a base URL.
From http://openid.net/specs.bml#linkrel:
- The openid.server URL MUST be an absolute URL. OpenID consumers
MUST NOT attempt to resolve relative URLs.
- The openid.server URL MUST NOT include entities other than &,
<, >, and ".
The parser ignores SGML comments and <![CDATA[blocks]]>. Both kinds of
quoting are allowed for attributes.
The parser deals with invalid markup in these ways:
- Tag names are not case-sensitive
- The <html> tag is accepted even when it is not at the top level
- The <head> tag is accepted even when it is not a direct child of
the <html> tag, but a <html> tag must be an ancestor of the <head>
tag
- <link> tags are accepted even when they are not direct children of
the <head> tag, but a <head> tag must be an ancestor of the <link>
tag
- If there is no closing tag for an open <html> or <head> tag, the
remainder of the document is viewed as being inside of the tag. If
there is no closing tag for a <link> tag, the link tag is treated
as a short tag. Exceptions to this rule are that <html> closes
<html> and <body> or <head> closes <head>
- Attributes of the <link> tag are not required to be quoted.
- In the case of duplicated attribute names, the attribute coming
last in the tag will be the value returned.
- Any text that does not parse as an attribute within a link tag will
be ignored. (e.g. <link pumpkin rel='openid.server' /> will ignore
pumpkin)
- If there are more than one <html> or <head> tag, the parser only

been added to the required arguments.
Required Arguments:
varname:
A string which will become the basis for the js variable name of
the marker, for this reason, your code should assign a unique
name for each GIcon you instantiate, otherwise there will be
name space collisions in your javascript.
Keyword Options:

shadow) image of the icon, in the format: (width, height) ex.:
GIcon('fast_food',

This method is preferred to direct subclassing of SQLAlchemy's

Typical usage::
import sqlalchemy.types as types
class MyType(types.TypeDecorator):
'''Prefixes Unicode values with "PREFIX:" on the way in and
strips it off on the way out.
'''
impl = types.Unicode
def process_bind_param(self, value, dialect):
return "PREFIX:" + value
def process_result_value(self, value, dialect):
return value[7:]
def copy(self):
return MyType(self.impl.length)
The class-level "impl" attribute is required, and can reference any
TypeEngine class. Alternatively, the load_dialect_impl() method
can be used to provide different type classes based on the dialect
given; in this case, the "impl" variable can reference
``TypeEngine`` as a placeholder.
Types that receive a Python type that isn't similar to the ultimate type
used may want to define the :meth:`TypeDecorator.coerce_compared_value`
method. This is used to give the expression system a hint when coercing
Python objects into bind parameters within expressions. Consider this
expression::
mytable.c.somecol + datetime.date(2009, 5, 15)
Above, if "somecol" is an ``Integer`` variant, it makes sense that
we're doing date arithmetic, where above is usually interpreted
by databases as adding a number of days to the given date.
The expression system does the right thing by not attempting to
coerce the "date()" value into an integer-oriented bind parameter.
However, in the case of ``TypeDecorator``, we are usually changing an
incoming Python type to something new - ``TypeDecorator`` by default will
"coerce" the non-typed side to be the same type as itself. Such as below,
we define an "epoch" type that stores a date value as an integer::
class MyEpochType(types.TypeDecorator):
impl = types.Integer
epoch = datetime.date(1970, 1, 1)
def process_bind_param(self, value, dialect):
return (value - self.epoch).days
def process_result_value(self, value, dialect):
return self.epoch + timedelta(days=value)
Our expression of ``somecol + date`` with the above type will coerce the
"date" on the right side to also be treated as ``MyEpochType``.
This behavior can be overridden via the
:meth:`~TypeDecorator.coerce_compared_value` method, which returns a type
that should be used for the value of the expression. Below we set it such
that an integer value will be treated as an ``Integer``, and any other
value is assumed to be a date and will be treated as a ``MyEpochType``::

if isinstance(value, int):

charge/communication delay). This is only safe to do if you are **sure**

# layers, it gets serialized as 'softmax_v2' instead of 'softmax' as the
# internal method name is returned in serialization. This results in errors in

"""Softmax converts a vector of values to a probability distribution.
The elements of the output vector are in range (0, 1) and sum to 1.
Each vector is handled independently. The `axis` argument sets which axis
of the input the function is applied along.
Softmax is often used as the activation for the last
layer of a classification network because the result could be interpreted as
a probability distribution.
The softmax of each vector x is computed as
`exp(x) / tf.reduce_sum(exp(x))`.
The input values in are the log-odds of the resulting probability.
Args:
x : Input tensor.
axis: Integer, axis along which the softmax normalization is applied.
Returns:
Tensor, output of softmax transformation (all values are non-negative

"""Exponential Linear Unit.
The exponential linear unit (ELU) with `alpha > 0` is:
`x` if `x > 0` and
`alpha * (exp(x) - 1)` if `x < 0`
The ELU hyperparameter `alpha` controls the value to which an
ELU saturates for negative net inputs. ELUs diminish the
vanishing gradient effect.
ELUs have negative values which pushes the mean of the activations
closer to zero.
Mean activations that are closer to zero enable faster learning as they
bring the gradient closer to the natural gradient.
ELUs saturate to a negative value when the argument gets smaller.
Saturation means a small derivative which decreases the variation
and the information that is propagated to the next layer.
Example Usage:
>>> import tensorflow as tf
>>> model = tf.keras.Sequential()
>>> model.add(tf.keras.layers.Conv2D(32, (3, 3), activation='elu',
... input_shape=(28, 28, 1)))

>>> model.add(tf.keras.layers.Conv2D(64, (3, 3), activation='elu'))
<tensorflow.python.keras.engine.sequential.Sequential object ...>
Args:

alpha: A scalar, slope of negative section. `alpha` controls the value to

The Scaled Exponential Linear Unit (SELU) activation function is defined as:

where `alpha` and `scale` are pre-defined constants
(`alpha=1.67326324` and `scale=1.05070098`).
Basically, the SELU activation function multiplies `scale` (> 1) with the
output of the `tf.keras.activations.elu` function to ensure a slope larger
than one for positive inputs.
The values of `alpha` and `scale` are
chosen so that the mean and variance of the inputs are preserved
between two consecutive layers as long as the weights are initialized
correctly (see `tf.keras.initializers.LecunNormal` initializer)
and the number of input units is "large enough"
(see reference paper for more information).
Example Usage:
>>> num_classes = 10 # 10-class problem
>>> model = tf.keras.Sequential()
>>> model.add(tf.keras.layers.Dense(64, kernel_initializer='lecun_normal',
... activation='selu'))

Args:

Returns:

- To be used together with the

- To be used together with the dropout variant
`tf.keras.layers.AlphaDropout` (not regular dropout).

A VS2008 project with most of the options defined was created through the
VS2008 IDE. It was then converted to VS2010. The tool settings found in
the .vcproj and .vcxproj files were converted to the two dictionaries
msvs_settings and expected_msbuild_settings.
Note that for many settings, the VS2010 converter adds macros like
%(AdditionalIncludeDirectories) to make sure than inherited values are
included. Since the Gyp projects we generate do not use inheritance,
we removed these macros. They were:

Caching framework.
This package defines set of cache backends that all conform to a simple API.
In a nutshell, a cache is a set of values -- which can be any object that
may be pickled -- identified by string keys. For the complete API, see
the abstract BaseCache class in django.core.cache.backends.base.
Client code should not access a cache backend directly; instead it should
either use the "cache" variable made available here, or it should use the
get_cache() function made available here. get_cache() takes a backend URI
(e.g. "memcached://127.0.0.1:11211/") and returns an instance of a backend
cache class.
See docs/topics/cache.txt for information on the public API.

class Variable(object):
"""See the @{$variables$Variables How To} for a high level overview.
A variable maintains state in the graph across calls to `run()`. You add a
variable to the graph by constructing an instance of the class `Variable`.
The `Variable()` constructor requires an initial value for the variable,
which can be a `Tensor` of any type and shape. The initial value defines the
type and shape of the variable. After construction, the type and shape of
the variable are fixed. The value can be changed using one of the assign
methods.
If you want to change the shape of a variable later you have to use an
`assign` Op with `validate_shape=False`.
Just like any `Tensor`, variables created with `Variable()` can be used as
inputs for other Ops in the graph. Additionally, all the operators
overloaded for the `Tensor` class are carried over to variables, so you can
also add nodes to the graph by just doing arithmetic on variables.
```python
import tensorflow as tf
# Create a variable.
w = tf.Variable(<initial-value>, name=<optional-name>)
# Use the variable in the graph like any Tensor.
y = tf.matmul(w, ...another variable or tensor...)
# The overloaded operators are available too.
z = tf.sigmoid(w + y)
# Assign a new value to the variable with `assign()` or a related method.
w.assign(w + 1.0)
w.assign_add(1.0)
```
When you launch the graph, variables have to be explicitly initialized before
you can run Ops that use their value. You can initialize a variable by
running its *initializer op*, restoring the variable from a save file, or
simply running an `assign` Op that assigns a value to the variable. In fact,
the variable *initializer op* is just an `assign` Op that assigns the
variable's initial value to the variable itself.
```python
# Launch the graph in a session.
with tf.Session() as sess:
# Run the variable initializer.
sess.run(w.initializer)
# ...you now can run ops that use the value of 'w'...
```
The most common initialization pattern is to use the convenience function
`global_variables_initializer()` to add an Op to the graph that initializes
all the variables. You then run that Op after launching the graph.
```python
# Add an Op to initialize global variables.
init_op = tf.global_variables_initializer()
# Launch the graph in a session.
with tf.Session() as sess:
# Run the Op that initializes global variables.
sess.run(init_op)
# ...you can now run any Op that uses variable values...
```
If you need to create a variable with an initial value dependent on another
variable, use the other variable's `initialized_value()`. This ensures that
variables are initialized in the right order.
All variables are automatically collected in the graph where they are
created. By default, the constructor adds the new variable to the graph
collection `GraphKeys.GLOBAL_VARIABLES`. The convenience function
`global_variables()` returns the contents of that collection.
When building a machine learning model it is often convenient to distinguish
between variables holding the trainable model parameters and other variables
such as a `global step` variable used to count training steps. To make this
easier, the variable constructor supports a `trainable=<bool>` parameter. If
`True`, the new variable is also added to the graph collection
`GraphKeys.TRAINABLE_VARIABLES`. The convenience function
`trainable_variables()` returns the contents of this collection. The
various `Optimizer` classes use this collection as the default list of
variables to optimize.

The new variable is added to the graph collections listed in `collections`,
which defaults to `[GraphKeys.GLOBAL_VARIABLES]`.
If `trainable` is `True` the variable is also added to the graph collection
`GraphKeys.TRAINABLE_VARIABLES`.
This constructor creates both a `variable` Op and an `assign` Op to set the
variable to its initial value.
Args:
initial_value: A `Tensor`, or Python object convertible to a `Tensor`,
which is the initial value for the Variable. The initial value must have
a shape specified unless `validate_shape` is set to False. Can also be a
callable with no argument that returns the initial value when called. In
that case, `dtype` must be specified. (Note that initializer functions
from init_ops.py must first be bound to a shape before being used here.)
trainable: If `True`, the default, also adds the variable to the graph
collection `GraphKeys.TRAINABLE_VARIABLES`. This collection is used as
the default list of variables to use by the `Optimizer` classes.
collections: List of graph collections keys. The new variable is added to
these collections. Defaults to `[GraphKeys.GLOBAL_VARIABLES]`.
validate_shape: If `False`, allows the variable to be initialized with a
value of unknown shape. If `True`, the default, the shape of
`initial_value` must be known.
caching_device: Optional device string describing where the Variable
should be cached for reading. Defaults to the Variable's device.
If not `None`, caches on another device. Typical use is to cache
on the device where the Ops using the Variable reside, to deduplicate
copying through `Switch` and other conditional statements.
name: Optional name for the variable. Defaults to `'Variable'` and gets
uniquified automatically.
variable_def: `VariableDef` protocol buffer. If not `None`, recreates
the Variable object with its contents, referencing the variable's nodes
in the graph, which must already exist. The graph is not changed.
`variable_def` and the other arguments are mutually exclusive.
dtype: If set, initial_value will be converted to the given type.
If `None`, either the datatype will be kept (if `initial_value` is
a Tensor), or `convert_to_tensor` will decide.
expected_shape: A TensorShape. If set, initial_value is expected
to have this shape.
import_scope: Optional `string`. Name scope to add to the
`Variable.` Only used when initializing from protocol buffer.
Raises:
ValueError: If both `variable_def` and initial_value are specified.
ValueError: If the initial value is not specified, or does not have a
shape and `validate_shape` is `True`.

'''Zulip notification change-commit hook.
In Perforce, The "change-commit" trigger is fired after a metadata has been
created, files have been transferred, and the changelist comitted to the depot
database.
This specific trigger expects command-line arguments in the form:
%change% %changeroot%
For example:
1234 //depot/security/src/
