OpenShift API (with Kubernetes)
OpenShift provides builds, application lifecycle, image content management, and administrative policy on top of Kubernetes. The API allows consistent management of those objects. All API operations are authenticated via an Authorization bearer token that is provided for service accounts as a generated secret (in JWT form) or via the native OAuth endpoint located at /oauth/authorize. Core infrastructure components may use openshift.client certificates that require no authentication. All API operations return a 'resourceVersion' string that represents the version of the object in the underlying storage. The standard LIST operation performs a snapshot read of the underlying objects, returning a resourceVersion representing a consistent version of the listed objects. The WATCH operation allows all updates to a set of objects after the provided resourceVersion to be observed by a openshift.client. By listing and beginning a watch from the returned resourceVersion, openshift.clients may observe a consistent view of the state of one or more objects. Note that WATCH always returns the update after the provided resourceVersion. Watch may be extended a limited time in the past - using etcd 2 the watch window is 1000 events (which on a large cluster may only be a few tens of seconds) so openshift.clients must explicitly handle the \"watch to old error\" by re-listing. Objects are divided into two rough categories - those that have a lifecycle and must reflect the state of the cluster, and those that have no state. Objects with lifecycle typically have three main sections: * 'metadata' common to all objects * a 'spec' that represents the desired state * a 'status' that represents how much of the desired state is reflected on the cluster at the current time Objects that have no state have 'metadata' but may lack a 'spec' or 'status' section. Objects are divided into those that are namespace scoped (only exist inside of a namespace) and those that are cluster scoped (exist outside of a namespace). A namespace scoped resource will be deleted when the namespace is deleted and cannot be created if the namespace has not yet been created or is in the process of deletion. Cluster scoped resources are typically only accessible to admins - resources like nodes, persistent volumes, and cluster policy. All objects have a schema that is a combination of the 'kind' and 'apiVersion' fields. This schema is additive only for any given version - no backwards incompatible changes are allowed without incrementing the apiVersion. The server will return and accept a number of standard responses that share a common schema - for instance, the common error type is 'metav1.Status' (described below) and will be returned on any error from the API server. The API is available in multiple serialization formats - the default is JSON (Accept: application/json and Content-Type: application/json) but openshift.clients may also use YAML (application/yaml) or the native Protobuf schema (application/vnd.kubernetes.protobuf). Note that the format of the WATCH API call is slightly different - for JSON it returns newline delimited objects while for Protobuf it returns length-delimited frames (4 bytes in network-order) that contain a 'versioned.Watch' Protobuf object. See the OpenShift documentation at https://docs.openshift.org for more information.

Because a Google map often uses several different icons, a name field has
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:
image:
The url of the image to be used as the icon on the map defaults
to 'G_DEFAULT_ICON'
iconsize:
a tuple representing the pixel size of the foreground (not the
shadow) image of the icon, in the format: (width, height) ex.:
GIcon('fast_food',
image="/media/icon/star.png",
iconsize=(15,10))
Would indicate your custom icon was 15px wide and 10px height.
shadow:
the url of the image of the icon's shadow
shadowsize:
a tuple representing the pixel size of the shadow image, format is
the same as ``iconsize``
iconanchor:

"""Tool for checking if patch contains a regression test.
By default runs against current patch but can be set to use any gerrit review
as specified by change number (uses 'git review -d').
Idea: take tests from patch to check, and run against code from previous patch.
If new tests pass, then no regression test, if new tests fails against old code
then either
* new tests depend on new code and cannot confirm regression test is valid
(false positive)
* new tests detects the bug being fixed (detect valid regression test)
Due to the risk of false positives, the results from this need some human
interpretation.

============================================================
Empirical evaluation of the impact of k-means initialization
============================================================
Evaluate the ability of k-means initializations strategies to make
the algorithm convergence robust as measured by the relative standard
deviation of the inertia of the clustering (i.e. the sum of distances
to the nearest cluster center).
The first plot shows the best inertia reached for each combination
of the model (``KMeans`` or ``MiniBatchKMeans``) and the init method
(``init="random"`` or ``init="kmeans++"``) for increasing values of the
``n_init`` parameter that controls the number of initializations.
The second plot demonstrate one single run of the ``MiniBatchKMeans``
estimator using a ``init="random"`` and ``n_init=1``. This run leads to
a bad convergence (local optimum) with estimated centers stuck
between ground truth clusters.
The dataset used for evaluation is a 2D grid of isotropic Gaussian
clusters widely spaced.

# Fields #
##########
Each Field class does some sort of validation. Each Field has a clean() method,
which either raises django.forms.ValidationError or returns the "clean"
data -- usually a Unicode object, but, in some rare cases, a list.
Each Field's __init__() takes at least these parameters:
required -- Boolean that specifies whether the field is required.
True by default.
widget -- A Widget class, or instance of a Widget class, that should be
used for this Field when displaying it. Each Field has a default
Widget that it'll use if you don't specify this. In most cases,
the default widget is TextInput.
label -- A verbose name for this field, for use in displaying this field in
a form. By default, Django will use a "pretty" version of the form
field name, if the Field is part of a Form.
initial -- A value to use in this Field's initial display. This value is
*not* used as a fallback if data isn't given.
Other than that, the Field subclasses have class-specific options for
__init__(). For example, CharField has a max_length option.

For an explanation of why this op was deprecated, and information on how to

The summary has up to `max_images` summary values containing images. The
images are built from `tensor` which must be 4-D with shape `[batch_size,
height, width, channels]` and where `channels` can be:
* 1: `tensor` is interpreted as Grayscale.

The images have the same number of channels as the input tensor. For float
input, the values are normalized one image at a time to fit in the range
`[0, 255]`. `uint8` values are unchanged. The op uses two different
normalization algorithms:
* If the input values are all positive, they are rescaled so the largest one
is 255.
* If any input value is negative, the values are shifted so input value 0.0
is at 127. They are then rescaled so that either the smallest value is 0,
or the largest one is 255.
The `tag` argument is a scalar `Tensor` of type `string`. It is used to
build the `tag` of the summary values:
* If `max_images` is 1, the summary value tag is '*tag*/image'.
* If `max_images` is greater than 1, the summary value tags are
generated sequentially as '*tag*/image/0', '*tag*/image/1', etc.

module: apk
short_description: Manages apk packages
description:
- Manages I(apk) packages for Alpine Linux.
author: "Kevin Brebanov (@kbrebanov)"
version_added: "2.0"
options:
available:
description:
- During upgrade, reset versioned world dependencies and change logic to prefer replacing or downgrading packages (instead of holding them)
if the currently installed package is no longer available from any repository.
type: bool
default: 'no'
version_added: "2.4"
name:
description:
- A package name, like C(foo), or multiple packages, like C(foo, bar).
repository:
description:
- A package repository or multiple repositories.
Unlike with the underlying apk command, this list will override the system repositories rather than supplement them.
version_added: "2.4"
state:
description:
- Indicates the desired package(s) state.
- C(present) ensures the package(s) is/are present.
- C(absent) ensures the package(s) is/are absent.
- C(latest) ensures the package(s) is/are present and the latest version(s).
default: present
choices: [ "present", "absent", "latest" ]
update_cache:
description:
- Update repository indexes. Can be run with other steps or on it's own.
type: bool
default: 'no'
upgrade:
description:
- Upgrade all installed packages to their latest version.
type: bool
default: 'no'
notes:
- '"name" and "upgrade" are mutually exclusive.'
- When used with a `loop:` each package will be processed individually, it is much more efficient to pass the list directly to the `name` option.

def annotate(**annotations):
"""Context Manager for setting HighLevelGraph Layer annotations.
Annotations are metadata or soft constraints associated with
tasks that dask schedulers may choose to respect: They signal intent
without enforcing hard constraints. As such, they are
primarily designed for use with the distributed scheduler.
Almost any object can serve as an annotation, but small Python objects
are preferred, while large objects such as NumPy arrays are discouraged.
Callables supplied as an annotation should take a single *key* argument and
produce the appropriate annotation. Individual task keys in the annotated collection
are supplied to the callable.
Parameters
----------
**annotations : key-value pairs
Examples
--------
All tasks within array A should have priority 100 and be retried 3 times
on failure.
>>> import dask
>>> import dask.array as da
>>> with dask.annotate(priority=100, retries=3):
... A = da.ones((10000, 10000))
Prioritise tasks within Array A on flattened block ID.

"""Persist this dask collection into memory
This turns a lazy Dask collection into a Dask collection with the same
metadata, but now with the results fully computed or actively computing
in the background.
The action of function differs significantly depending on the active
task scheduler. If the task scheduler supports asynchronous computing,
such as is the case of the dask.distributed scheduler, then persist
will return *immediately* and the return value's task graph will
contain Dask Future objects. However if the task scheduler only
supports blocking computation then the call to persist will *block*
and the return value's task graph will contain concrete Python results.
This function is particularly useful when using distributed systems,
because the results will be kept in distributed memory, rather than
returned to the local process as with compute.
Parameters
----------
scheduler : string, optional
Which scheduler to use like "threads", "synchronous" or "processes".
If not provided, the default is to check the global settings first,
and then fall back to the collection defaults.
optimize_graph : bool, optional
If True [default], the graph is optimized before computation.
Otherwise the graph is run as is. This can be useful for debugging.

This function operates differently if a ``dask.distributed.Client`` exists

When using Dask on a single machine you should ensure that the dataset fits

"""Tokenization help for Python programs.
generate_tokens(readline) is a generator that breaks a stream of
text into Python tokens. It accepts a readline-like method which is called
repeatedly to get the next line of input (or "" for EOF). It generates
5-tuples with these members:
the token type (see token.py)
the token (a string)
the starting (row, column) indices of the token (a 2-tuple of ints)
the ending (row, column) indices of the token (a 2-tuple of ints)
the original line (string)
It is designed to match the working of the Python tokenizer exactly, except
that it produces COMMENT tokens for comments and gives type OP for all
operators

short_description: Manage the system attributes on Cisco NXOS devices
description:
- This module provides declarative management of node system attributes
on Cisco NXOS devices. It provides an option to configure host system
parameters or remove those parameters from the device active
configuration.
options:
hostname:
description:
- Configure the device hostname parameter. This option takes an ASCII string value.
domain_name:
description:
- Configures the default domain
name suffix to be used when referencing this node by its
FQDN. This argument accepts either a list of domain names or
a list of dicts that configure the domain name and VRF name. See
examples.
domain_lookup:
description:
- Enables or disables the DNS
lookup feature in Cisco NXOS. This argument accepts boolean
values. When enabled, the system will try to resolve hostnames
using DNS and when disabled, hostnames will not be resolved.
domain_search:
description:
- Configures a list of domain
name suffixes to search when performing DNS name resolution.
This argument accepts either a list of domain names or
a list of dicts that configure the domain name and VRF name. See
examples.
name_servers:
description:
- List of DNS name servers by IP address to use to perform name resolution
lookups. This argument accepts either a list of DNS servers or
a list of hashes that configure the name server and VRF name. See
examples.
system_mtu:
description:
- Specifies the mtu, must be an integer.
state:
description:
- State of the configuration
values in the device's current active configuration. When set
to I(present), the values should be configured in the device active
configuration and when set to I(absent) the values should not be
in the device active configuration
default: present
choices: ['present', 'absent']

=======================================================================
Shrinkage covariance estimation: LedoitWolf vs OAS and max-likelihood
=======================================================================
When working with covariance estimation, the usual approach is to use
a maximum likelihood estimator, such as the
:class:`sklearn.covariance.EmpiricalCovariance`. It is unbiased, i.e. it
converges to the true (population) covariance when given many
observations. However, it can also be beneficial to regularize it, in
order to reduce its variance; this, in turn, introduces some bias. This
example illustrates the simple regularization used in
:ref:`shrunk_covariance` estimators. In particular, it focuses on how to
set the amount of regularization, i.e. how to choose the bias-variance
trade-off.
Here we compare 3 approaches:
* Setting the parameter by cross-validating the likelihood on three folds
according to a grid of potential shrinkage parameters.
* A close formula proposed by Ledoit and Wolf to compute
the asymptotically optimal regularization parameter (minimizing a MSE
criterion), yielding the :class:`sklearn.covariance.LedoitWolf`
covariance estimate.
* An improvement of the Ledoit-Wolf shrinkage, the
:class:`sklearn.covariance.OAS`, proposed by Chen et al. Its
convergence is significantly better under the assumption that the data
are Gaussian, in particular for small samples.
To quantify estimation error, we plot the likelihood of unseen data for
different values of the shrinkage parameter. We also show the choices by
cross-validation, or with the LedoitWolf and OAS estimates.
Note that the maximum likelihood estimate corresponds to no shrinkage,
and thus performs poorly. The Ledoit-Wolf estimate performs really well,
as it is close to the optimal and is computational not costly. In this
example, the OAS estimate is a bit further away. Interestingly, both
approaches outperform cross-validation, which is significantly most
computationally costly.

"""Outputs deterministic pseudorandom values from a uniform distribution.
This is a stateless version of `tf.random_uniform`: if run twice with the
same seeds, it will produce the same pseudorandom numbers. The output is
consistent across multiple runs on the same hardware (and between CPU
and GPU), but may change between versions of TensorFlow or on non-CPU/GPU
hardware.
The generated values follow a uniform distribution in the range
`[minval, maxval)`. The lower bound `minval` is included in the range, while
the upper bound `maxval` is excluded.
For floats, the default range is `[0, 1)`. For ints, at least `maxval` must
be specified explicitly.
In the integer case, the random integers are slightly biased unless
`maxval - minval` is an exact power of two. The bias is small for values of
`maxval - minval` significantly smaller than the range of the output (either
`2**32` or `2**64`).

seed: A shape [2] integer Tensor of seeds to the random number generator.
minval: A 0-D Tensor or Python value of type `dtype`. The lower bound on the

=======================================================================
Shrinkage covariance estimation: LedoitWolf vs OAS and max-likelihood
=======================================================================
The usual estimator for covariance is the maximum likelihood estimator,
:class:`sklearn.covariance.EmpiricalCovariance`. It is unbiased, i.e. it
converges to the true (population) covariance when given many
observations. However, it can also be beneficial to regularize it, in
order to reduce its variance; this, in turn, introduces some bias. This
example illustrates the simple regularization used in
:ref:`shrunk_covariance` estimators. In particular, it focuses on how to
set the amount of regularization, i.e. how to choose the bias-variance
trade-off.
Here we compare 3 approaches:
* Setting the parameter by cross-validating the likelihood on three folds
according to a grid of potential shrinkage parameters.
* A close formula proposed by Ledoit and Wolf to compute
the asymptotical optimal regularization parameter (minimizing a MSE
criterion), yielding the :class:`sklearn.covariance.LedoitWolf`
covariance estimate.
* An improvement of the Ledoit-Wolf shrinkage, the
:class:`sklearn.covariance.OAS`, proposed by Chen et al. Its
convergence is significantly better under the assumption that the data
are Gaussian, in particular for small samples.
To quantify estimation error, we plot the likelihood of unseen data for
different values of the shrinkage parameter. We also show the choices by
cross-validation, or with the LedoitWolf and OAS estimates.
Note that the maximum likelihood estimate corresponds to no shrinkage,
and thus performs poorly. The Ledoit-Wolf estimate performs really well,
as it is close to the optimal and is computational not costly. In this
example, the OAS estimate is a bit further away. Interestingly, both
approaches outperform cross-validation, which is significantly most
computationally costly.
