// Adds one or more tags to an IAM role. The role can be a regular role or a
// service-linked role. If a tag with the same key name already exists, then that
// tag is overwritten with the new value. A tag consists of a key name and an
// associated value. By assigning tags to your resources, you can do the
// following:
//
// * Administrative grouping and discovery - Attach tags to resources
// to aid in organization and search. For example, you could search for all
// resources with the key name Project and the value MyImportantProject. Or search
// for all resources with the key name Cost Center and the value 41200.
//
// * Access
// control - Reference tags in IAM user-based and resource-based policies. You can
// use tags to restrict access to only an IAM user or role that has a specified tag
// attached. You can also restrict access to only those resources that have a
// certain tag attached. For examples of policies that show how to use tags to
// control access, see Control Access Using IAM Tags
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_tags.html) in the IAM
// User Guide.
//
// * Cost allocation - Use tags to help track which individuals and
// teams are using which AWS resources.
//
// * Make sure that you have no invalid tags
// and that you do not exceed the allowed number of tags per role. In either case,
// the entire request fails and no tags are added to the role.
//
// * AWS always
// interprets the tag Value as a single string. If you need to store an array, you
// can store comma-separated values in the string. However, you must interpret the
// value in your code.

Ordinary least squares Linear Regression.
LinearRegression fits a linear model with coefficients w = (w1, ..., wp)
to minimize the residual sum of squares between the observed targets in

Parameters
----------
fit_intercept : bool, default=True
Whether to calculate the intercept for this model. If set
to False, no intercept will be used in calculations
(i.e. data is expected to be centered).
normalize : bool, default=False
This parameter is ignored when ``fit_intercept`` is set to False.
If True, the regressors X will be normalized before regression by
subtracting the mean and dividing by the l2-norm.
If you wish to standardize, please use
:class:`~sklearn.preprocessing.StandardScaler` before calling ``fit``
on an estimator with ``normalize=False``.
copy_X : bool, default=True
If True, X will be copied; else, it may be overwritten.
n_jobs : int, default=None
The number of jobs to use for the computation. This will only provide
speedup for n_targets > 1 and sufficient large problems.
``None`` means 1 unless in a :obj:`joblib.parallel_backend` context.
``-1`` means using all processors. See :term:`Glossary <n_jobs>`
for more details.
positive : bool, default=False
When set to ``True``, forces the coefficients to be positive. This
option is only supported for dense arrays.
.. versionadded:: 0.24
Attributes
----------
coef_ : array of shape (n_features, ) or (n_targets, n_features)
Estimated coefficients for the linear regression problem.
If multiple targets are passed during the fit (y 2D), this
is a 2D array of shape (n_targets, n_features), while if only
one target is passed, this is a 1D array of length n_features.
rank_ : int
Rank of matrix `X`. Only available when `X` is dense.
singular_ : array of shape (min(X, y),)
Singular values of `X`. Only available when `X` is dense.
intercept_ : float or array of shape (n_targets,)
Independent term in the linear model. Set to 0.0 if
`fit_intercept = False`.
See Also
--------
Ridge : Ridge regression addresses some of the
problems of Ordinary Least Squares by imposing a penalty on the
size of the coefficients with l2 regularization.
Lasso : The Lasso is a linear model that estimates
sparse coefficients with l1 regularization.
ElasticNet : Elastic-Net is a linear regression
model trained with both l1 and l2 -norm regularization of the
coefficients.

Each channel of the input Tensor is incremented by a sinusoid of a different
frequency and phase.
This allows attention to learn to use absolute and relative positions.
Timing signals should be added to some precursors of both the query and the
memory inputs to attention.
The use of relative position is possible because sin(x+y) and cos(x+y) can be
expressed in terms of y, sin(x) and cos(x).
In particular, we use a geometric sequence of timescales starting with
min_timescale and ending with max_timescale. The number of different
timescales is equal to channels / 2. For each timescale, we
generate the two sinusoidal signals sin(timestep/timescale) and
cos(timestep/timescale). All of these sinusoids are concatenated in
the channels dimension.

r"""Network unit that computes pairwise bilinear label scores.
Given source and target representations for each token, this network unit
computes bilinear scores for each label for each of the N^2 combinations of
source and target tokens, rather than for only N already-computed
source/target pairs (as is performed by the biaffine_units). The output is
suitable as input to e.g. the heads_labels transition system.
Specifically, a weights tensor W called `bilinear' is used to compute bilinear
scores B for input tensors S and T:
B_{bnml} = \sum_{i,j} S_{bni} W_{ilj} T{bmj}
for batches b, steps n and m and labels l.
Parameters:
num_labels: The number of dependency labels, L.
Features:
sources: [B * N, S] matrix of batched activations for source tokens.
targets: [B * N, T] matrix of batched activations for target tokens.
Layers:
bilinear_scores: [B * N, N * L] matrix where vector b*N*N*L+t contains
per-label scores for all N possible arcs from token t in
batch b.

Installation of Cabal Packages
==============================
.. versionadded:: 2015.8.0
These states manage the installed packages for Haskell using
cabal. Note that cabal-install must be installed for these states to
be available, so cabal states should include a requisite to a
pkg.installed state for the package which provides cabal
(``cabal-install`` in case of Debian based distributions). Example::
.. code-block:: yaml
cabal-install:
pkg.installed
ShellCheck:
cabal.installed:
- require:
- pkg: cabal-install

Parse pkg string and return a tuple of packge name, separator, and
package version.

support for other forms can be added later.

"""Works exactly like a dict but provides ways to fill it from files
or special dictionaries. There are two common patterns to populate the
config.
Either you can fill the config from a config file::
app.config.from_pyfile('yourconfig.cfg')
Or alternatively you can define the configuration options in the
module that calls :meth:`from_object` or provide an import path to
a module that should be loaded. It is also possible to tell it to
use the same module and with that provide the configuration values
just before the call::
DEBUG = True
SECRET_KEY = 'development key'
app.config.from_object(__name__)
In both cases (loading from any Python file or loading from modules),
only uppercase keys are added to the config. This makes it possible to use
lowercase values in the config file for temporary values that are not added
to the config or to define the config keys in the same file that implements
the application.
Probably the most interesting way to load configurations is from an
environment variable pointing to a file::
app.config.from_envvar('YOURAPPLICATION_SETTINGS')
In this case before launching the application you have to set this
environment variable to the file you want to use. On Linux and OS X
use the export statement::
export YOURAPPLICATION_SETTINGS='/path/to/config/file'
On windows use `set` instead.

config object is created by the application, this is

loads only the uppercase attributes of the module/class. A ``dict``

rather configuration defaults. The actual config should be loaded

*
* - `process.nextTick` is only Node.js.

* - Everything else is browser based (e.g., mutation observer, requestAnimationFrame, etc).
* - Only API which is universal is `setTimeout`.
* - Note that `0` is not actually `0ms`. Browser environments commonly have a minimum delay of `4ms`. This is acceptable. Here, the main intent of this function is to give the runtime a chance to run garbage collection, clear state, and tend to any other pending tasks before returning control to benchmark tasks. The larger aim (attainable or not) is to provide each benchmark run with as much of a fresh state as possible.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

on a module. Configuration is done at instantiation first, by passing in the
Terraform root module path, and then in the setup method through files that
will be temporarily linked in the module, and Terraform variables.
The standard way of using this is by calling setup to configure the module
through temporarily linked Terraform files and variables, run one or more
Terraform commands, then check command output, state, or created resources
from individual tests.
The local .terraform directory (including local state) and any linked file
are removed when the instance is garbage collected. Destroy needs to be
called explicitly using destroy().
Args:
tfdir: the Terraform module directory to test, either an absolute path, or
relative to basedir.
basedir: optional base directory to use for relative paths, defaults to the
directory above the one this module lives in.
terraform: path to the Terraform command.
env: a dict with custom environment variables to pass to terraform.
