Hi folks, I just released version 0.9.3 of the Pythran package, Short reminder: Pythran is an ahead-of-time compiler for scientific Python, with a focus on high-level numerical kernels, parallelism and vectorisation. Here is a simple kernel example, with a pythran annotation. Note that that kernel is still Python-compatible (from https://stackoverflow.com/questions/57199248/) : import numpy as np #pythran export col_sum(int[:,:] or float[:,:], int[:]) def col_sum(data, idx): return data.T[idx].sum(0) The Pythran package is available on PyPI, Github and Conda https://pypi.org/project/pythran/ https://anaconda.org/conda-forge/pythran https://github.com/serge-sans-paille/pythran The interested reader can have a look to the changelog for details https://pythran.readthedocs.io/en/latest/Changelog.html Long story short: bug fixes and better 32bit arch support. Plus (Thanks to Miro Hrončok), pythran is now available on Fedora \o/ Huge thanks to all contributors and bug reporters: Jean Laroche Yann Diorcet DWesl Miro Hrončok Piotr Bartmann Jochen Schröder Sylwester Arabas Marti Bosch rorroiga Pierre Augier Anubhab Haldar nbecker
