"""Joblib is a set of tools to provide **lightweight pipelining in
Python**. In particular:

1. transparent disk-caching of functions and lazy re-evaluation
   (memoize pattern)

2. easy simple parallel computing

Joblib is optimized to be **fast** and **robust** on large
data in particular and has specific optimizations for `numpy` arrays. It is
**BSD-licensed**.

==================== ===============================================
    **Documentation:**       https://joblib.readthedocs.io

**Download:**            https://pypi.python.org/pypi/joblib#downloads

**Source code:**         https://github.com/joblib/joblib

**Report issues:**       https://github.com/joblib/joblib/issues
    ==================== ===============================================

Vision
--------

The vision is to provide tools to easily achieve better performance and
reproducibility when working with long running jobs.

*  **Avoid computing the same thing twice**: code is often rerun again and
    again, for instance when prototyping computational-heavy jobs (as in
    scientific development), but hand-crafted solutions to alleviate this
    issue are error-prone and often lead to unreproducible results.

*  **Persist to disk transparently**: efficiently persisting
    arbitrary objects containing large data is hard. Using
    joblib's caching mechanism avoids hand-written persistence and
    implicitly links the file on disk to the execution context of
    the original Python object. As a result, joblib's persistence is
    good for resuming an application status or computational job, eg
    after a crash.

Joblib addresses these problems while **leaving your code and your flow
control as unmodified as possible** (no framework, no new paradigms).

Main features
------------------

1) **Transparent and fast disk-caching of output value:** a memoize or
   make-like functionality for Python functions that works well for
   arbitrary Python objects, including very large numpy arrays. Separate
   persistence and flow-execution logic from domain logic or algorithmic
   code by writing the operations as a set of steps with well-defined
   inputs and  outputs: Python functions. Joblib can save their
   computation to disk and rerun it only if necessary::

>>> from joblib import Memory
      >>> cachedir = 'your_cache_dir_goes_here'
      >>> mem = Memory(cachedir)
      >>> import numpy as np
      >>> a = np.vander(np.arange(3)).astype(float)
      >>> square = mem.cache(np.square)
      >>> b = square(a)                                   # doctest: +ELLIPSIS
      ______________________________________________________________________...
      [Memory] Calling square...
      square(array([[0., 0., 1.],
             [1., 1., 1.],
             [4., 2., 1.]]))
      _________________________________________________...square - ...s, 0.0min

>>> c = square(a)
      >>> # The above call did not trigger an evaluation

2) **Embarrassingly parallel helper:** to make it easy to write readable
   parallel code and debug it quickly::

>>> from joblib import Parallel, delayed
      >>> from math import sqrt
      >>> Parallel(n_jobs=1)(delayed(sqrt)(i**2) for i in range(10))
      [0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0]

3) **Fast compressed Persistence**: a replacement for pickle to work
   efficiently on Python objects containing large data (
   *joblib.dump* & *joblib.load* ).

..
    >>> import shutil ; shutil.rmtree(cachedir)
