Unofficial Windows Binaries for Python Extension Packages

by Christoph Gohlke, Laboratory for Fluorescence Dynamics, University of California, Irvine.

This page provides 32- and 64-bit Windows binaries of many scientific open-source extension packages for the official CPython distribution of the Python programming language.

The files are unofficial (meaning: informal, unrecognized, personal, unsupported, no warranty, no liability, provided "as is") and made available for testing and evaluation purposes.

If downloads fail reload this page, enable JavaScript, disable download managers, disable proxies, clear cache, and use Firefox. Please only download files as needed.

Most binaries are built from source code found on PyPI or in the projects public revision control systems. Source code changes, if any, have been submitted to the project maintainers or are included in the packages.

Refer to the documentation of the individual packages for license restrictions and dependencies

Many binaries depend on Numpy-MKL 1.8 and the Microsoft Visual C++ 2008 (x64, x86, and SP1 for CPython 2.6 to 3.2) or Visual C++ 2010 (x64, x86, for CPython 3.3 and 3.4) redistributable packages.

The binaries are compatible with the official CPython distribution on Windows >=6.0. Chances are they don't work with custom Python distributions included with Blender, Maya, ArcGIS, OSGeo4W, Cygwin, Pythonxy, Canopy, EPD, Anaconda, WinPython etc. Many binaries are not compatible with Windows XP or Wine.

The installers are ZIP or 7z files, which allows for manual or scripted repackaging or installation of the content.

The files are provided "as is" without warranty or support of any kind. The entire risk as to the quality and performance is with you.
