Pythran
#######
https://pythran.readthedocs.io
What is it?
-----------
Pythran is an ahead of time compiler for a subset of the Python language, with a
focus on scientific computing. It takes a Python module annotated with a few
interface descriptions and turns it into a native Python module with the same
interface, but (hopefully) faster.
It is meant to efficiently compile **scientific programs**, and takes advantage
of multi-cores and SIMD instruction units.
Until 0.9.5 (included), Pythran was supporting Python 3 and Python 2.7.
It now only supports Python **3.7** and upward.
Installation
------------
Pythran sources are hosted on https://github.com/serge-sans-paille/pythran.
Pythran releases are hosted on https://pypi.python.org/pypi/pythran.
Pythran is available on conda-forge on https://anaconda.org/conda-forge/pythran.
Debian/Ubuntu
=============
Using ``pip``
*************
1. Gather dependencies:
Pythran depends on a few Python modules and several C++ libraries. On a debian-like platform, run::
$> sudo apt-get install libatlas-base-dev
$> sudo apt-get install python-dev python-ply python-numpy
2. Install with ``pip``::
$> pip install pythran
Using ``mamba`` or ``conda``
****************************
1. Using ``mamba`` (https://github.com/conda-forge/miniforge) or ``conda`` (https://github.com/conda-forge/miniforge)
2. Run::
$> mamba install -c conda-forge pythran
or::
$> conda install -c conda-forge pythran
Mac OSX
=======
Using brew (https://brew.sh/)::
$> pip install pythran
$> brew install openblas
$> printf '[compiler]\nblas=openblas\ninclude_dirs=/usr/local/opt/openblas/include\nlibrary_dirs=/usr/local/opt/openblas/lib' > ~/.pythranrc
Depending on your setup, you may need to add the following to your ``~/.pythranrc`` file::
[compiler]
CXX=g++-4.9
CC=gcc-4.9
ArchLinux
=========
Using ``pacman``::
$> pacman -S python-pythran
Fedora
======
Using ``dnf``::
$> dnf install pythran
Windows
=======
Windows support is on going and only targets Python 3.5+ with either Visual Studio 2017 or, better, clang-cl::
$> pip install pythran
Note that using ``clang-cl.exe`` is the default setting. It can be changed
through the ``CXX`` and ``CC`` environment variables.
Other Platform
==============
See MANUAL file.
Basic Usage
-----------
A simple pythran input could be ``dprod.py``
.. code-block:: python
"""
Naive dotproduct! Pythran supports numpy.dot
"""
#pythran export dprod(int list, int list)
def dprod(l0,l1):
"""WoW, generator expression, zip and sum."""
return sum(x * y for x, y in zip(l0, l1))
To turn it into a native module, run::
$> pythran dprod.py
That will generate a native dprod.so that can be imported just like the former
module::
$> python -c 'import dprod' # this imports the native module instead
Documentation
-------------
The user documentation is available in the MANUAL file from the doc directory.
The developer documentation is available in the DEVGUIDE file from the doc
directory. There is also a TUTORIAL file for those who don't like reading
documentation.
The CLI documentation is available from the pythran help command::
$> pythran --help
Some extra developer documentation is also available using pydoc. Beware, this
is the computer science incarnation for the famous Where's Waldo? game::
$> pydoc pythran
$> pydoc pythran.typing
$> pydoc -b # in the browser

--------
