There are several +prominent libraries for handling OAuth requests, but they all suffer from one or +both of the following: + +1. They predate the `OAuth 1.0 spec`_, AKA RFC 5849. +2. They predate the `OAuth 2.0 spec`_, AKA RFC 6749. +3. They assume the usage of a specific HTTP request library. + +.. _`OAuth 1.0 spec`: https://tools.ietf.org/html/rfc5849 +.. _`OAuth 2.0 spec`: https://tools.ietf.org/html/rfc6749 + +OAuthLib is a framework which implements the logic of OAuth1 or OAuth2 without +assuming a specific HTTP request object or web framework. Use it to graft OAuth +client support onto your favorite HTTP library, or provide support onto your +favourite web framework. If you're a maintainer of such a library, write a thin +veneer on top of OAuthLib and get OAuth support for very little effort. + + +Documentation +-------------- + +Full documentation is available on `Read the Docs`_.

Optimized +einsum is agnostic to the backend and can handle NumPy, Dask, PyTorch, +Tensorflow, CuPy, Sparse, Theano, JAX, and Autograd arrays as well as potentially +any library which conforms to a standard API. See the +[**documentation**](http://optimized-einsum.readthedocs.io) for more +information. + +## Example usage + +The [`opt_einsum.contract`](https://optimized-einsum.readthedocs.io/en/latest/autosummary/opt_einsum.contract.html#opt-einsum-contract) +function can often act as a drop-in replacement for `einsum` +functions without futher changes to the code while providing superior performance. +Here, a tensor contraction is preformed with and without optimization: + +```python +import numpy as np +from opt_einsum import contract + +N = 10 +C = np.random.rand(N, N) +I = np.random.rand(N, N, N, N) + +%timeit np.einsum('pi,qj,ijkl,rk,sl->pqrs', C, C, I, C, C) +1 loops, best of 3: 934 ms per loop + +%timeit contract('pi,qj,ijkl,rk,sl->pqrs', C, C, I, C, C) +1000 loops, best of 3: 324 us per loop +``` + +In this particular example, we see a ~3000x performance improvement which is +not uncommon when compared against unoptimized contractions. See the [backend +examples](https://optimized-einsum.readthedocs.io/en/latest/backends.html) +for more information on using other backends. + +## Features + +The algorithms found in this repository often power the `einsum` optimizations +in many of the above projects. For example, the optimization of `np.einsum` +has been passed upstream and most of the same features that can be found in +this repository can be enabled with `np.einsum(..., optimize=True)`. However, +this repository often has more up to date algorithms for complex contractions. + +The following capabilities are enabled by `opt_einsum`: + +* Inspect [detailed information](http://optimized-einsum.readthedocs.io/en/latest/path_finding.html) about the path chosen. +* Perform contractions with [numerous backends](http://optimized-einsum.readthedocs.io/en/latest/backends.html), including on the GPU and with libraries such as [TensorFlow](https://www.tensorflow.org) and [PyTorch](https://pytorch.org). +* Generate [reusable expressions](http://optimized-einsum.readthedocs.io/en/latest/reusing_paths.html), potentially with [constant tensors](http://optimized-einsum.readthedocs.io/en/latest/reusing_paths.html#specifying-constants), that can be compiled for greater performance. +* Use an arbitrary number of indices to find contractions for [hundreds or even thousands of tensors](http://optimized-einsum.readthedocs.io/en/latest/ex_large_expr_with_greedy.html). +* Share [intermediate computations](http://optimized-einsum.readthedocs.io/en/latest/sharing_intermediates.html) among multiple contractions. +* Compute gradients of tensor contractions using [autograd](https://github.com/HIPS/autograd) or [jax](https://github.com/google/jax) + +Please see the [documentation](http://optimized-einsum.readthedocs.io/en/latest/?badge=latest) for more features! + + +## Installation + +`opt_einsum` can either be installed via `pip install opt_einsum` or from conda `conda install opt_einsum -c conda-forge`.

The *camera_num* + parameter (which defaults to 0) selects the camera module that the instance + will represent. Only the Raspberry Pi compute module currently supports + more than one camera. + + The *sensor_mode*, *resolution*, *framerate*, *framerate_range*, and + *clock_mode* parameters provide initial values for the :attr:`sensor_mode`, + :attr:`resolution`, :attr:`framerate`, :attr:`framerate_range`, and + :attr:`clock_mode` attributes of the class (these attributes are all + relatively expensive to set individually, hence setting them all upon + construction is a speed optimization). Please refer to the attribute + documentation for more information and default values. + + The *stereo_mode* and *stereo_decimate* parameters configure dual cameras + on a compute module for sterescopic mode. These parameters can only be set + at construction time; they cannot be altered later without closing the + :class:`PiCamera` instance and recreating it. The *stereo_mode* parameter + defaults to ``'none'`` (no stereoscopic mode) but can be set to + ``'side-by-side'`` or ``'top-bottom'`` to activate a stereoscopic mode. If + the *stereo_decimate* parameter is ``True``, the resolution of the two + cameras will be halved so that the resulting image has the same dimensions + as if stereoscopic mode were not being used. + + The *led_pin* parameter can be used to specify the GPIO pin which should be + used to control the camera's LED via the :attr:`led` attribute. If this is + not specified, it should default to the correct value for your Pi platform. + You should only need to specify this parameter if you are using a custom + DeviceTree blob (this is only typical on the `Compute Module`_ platform). + + No preview or recording is started automatically upon construction. Use + the :meth:`capture` method to capture images, the :meth:`start_recording` + method to begin recording video, or the :meth:`start_preview` method to + start live display of the camera's input. + + Several attributes are provided to adjust the camera's configuration. Some + of these can be adjusted while a recording is running, like + :attr:`brightness`.

The renderer sees the text and +# draws it from left to right. The text itself when ordered naturally is read +# backwards. A buffer of Visual Hebrew generally looks like so: +# "[last word of first line spelled backwards] [whole line ordered backwards +# and spelled backwards] [first word of first line spelled backwards] +# [end of line] [last word of second line] ... etc' " +# adding punctuation marks, numbers and English text to visual text is +# naturally also "visual" and from left to right. +# +# "Logical" directionality means the text is ordered "naturally" according to +# the order it is read. It is the responsibility of the renderer to display +# the text from right to left. A BIDI algorithm is used to place general +# punctuation marks, numbers and English text in the text. +# +# Texts in x-mac-hebrew are almost impossible to find on the Internet. From +# what little evidence I could find, it seems that its general directionality +# is Logical. +# +# To sum up all of the above, the Hebrew probing mechanism knows about two +# charsets: +# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are +# backwards while line order is natural. For charset recognition purposes +# the line order is unimportant (In fact, for this implementation, even +# word order is unimportant). +# Logical Hebrew - "windows-1255" - normal, naturally ordered text. +# +# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be +# specifically identified. +# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew +# that contain special punctuation marks or diacritics is displayed with +# some unconverted characters showing as question marks. This problem might +# be corrected using another model prober for x-mac-hebrew. Due to the fact +# that x-mac-hebrew texts are so rare, writing another model prober isn't +# worth the effort and performance hit. +# +#### The Prober #### +# +# The prober is divided between two SBCharSetProbers and a HebrewProber, +# all of which are managed, created, fed data, inquired and deleted by the +# SBCSGroupProber. The two SBCharSetProbers identify that the text is in +# fact some kind of Hebrew, Logical or Visual. The final decision about which +# one is it is made by the HebrewProber by combining final-letter scores +# with the scores of the two SBCharSetProbers to produce a final answer. +# +# The SBCSGroupProber is responsible for stripping the original text of HTML +# tags, English characters, numbers, low-ASCII punctuation characters, spaces +# and new lines. It reduces any sequence of such characters to a single space. +# The buffer fed to each prober in the SBCS group prober is pure text in +# high-ASCII. +# The two SBCharSetProbers (model probers) share the same language model: +# Win1255Model. +# The first SBCharSetProber uses the model normally as any other +# SBCharSetProber does, to recognize windows-1255, upon which this model was +# built. The second SBCharSetProber is told to make the pair-of-letter +# lookup in the language model backwards. This in practice exactly simulates +# a visual Hebrew model using the windows-1255 logical Hebrew model. +# +# The HebrewProber is not using any language model. All it does is look for +# final-letter evidence suggesting the text is either logical Hebrew or visual +# Hebrew. Disjointed from the model probers, the results of the HebrewProber +# alone are meaningless. HebrewProber always returns 0.00 as confidence +# since it never identifies a charset by itself. Instead, the pointer to the +# HebrewProber is passed to the model probers as a helper "Name Prober". +# When the Group prober receives a positive identification from any prober, +# it asks for the name of the charset identified. If the prober queried is a +# Hebrew model prober, the model prober forwards the call to the +# HebrewProber to make the final decision. In the HebrewProber, the +# decision is made according to the final-letters scores maintained and Both +# model probers scores.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.
+
+This module is deprecated. Users are directed to :mod:`importlib.resources`,
+:mod:`importlib.metadata` and :pypi:`packaging` instead.

+    Pygments
+    ~~~~~~~~
+
+    Pygments is a syntax highlighting package written in Python.
+
+    It is a generic syntax highlighter for general use in all kinds of software
+    such as forum systems, wikis or other applications that need to prettify
+    source code. Highlights are:
+
+    * a wide range of common languages and markup formats is supported
+    * special attention is paid to details, increasing quality by a fair amount
+    * support for new languages and formats are added easily
+    * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+      formats that PIL supports, and ANSI sequences
+    * it is usable as a command-line tool and as a library
+    * ... and it highlights even Brainfuck!
+
+    The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.

+      - ``op_expr`` is the pyparsing expression for the operator; may also
+        be a string, which will be converted to a Literal; if ``num_operands``
+        is 3, ``op_expr`` is a tuple of two expressions, for the two
+        operators separating the 3 terms
+      - ``num_operands`` is the number of terms for this operator (must be 1,
+        2, or 3)
+      - ``right_left_assoc`` is the indicator whether the operator is right
+        or left associative, using the pyparsing-defined constants
+        ``OpAssoc.RIGHT`` and ``OpAssoc.LEFT``.
+      - ``parse_action`` is the parse action to be associated with
+        expressions matching this operator expression (the parse action
+        tuple member may be omitted); if the parse action is passed
+        a tuple or list of functions, this is equivalent to calling
+        ``set_parse_action(*fn)``
+        (:class:`ParserElement.set_parse_action`)
+    - ``lpar`` - expression for matching left-parentheses; if passed as a
+      str, then will be parsed as ``Suppress(lpar)``. If lpar is passed as
+      an expression (such as ``Literal('(')``), then it will be kept in
+      the parsed results, and grouped with them. (default= ``Suppress('(')``)
+    - ``rpar`` - expression for matching right-parentheses; if passed as a
+      str, then will be parsed as ``Suppress(rpar)``. If rpar is passed as
+      an expression (such as ``Literal(')')``), then it will be kept in
+      the parsed results, and grouped with them. (default= ``Suppress(')')``)

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
