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 open-source extension packages for the official CPython distribution of the Python programming language.

The files are unofficial (meaning: informal, unrecognized, personal, unsupported) and made available for testing and evaluation purposes only. Consider using the Python(x,y), ActiveState, or Enthought distributions if you are new to Python or need support.

If downloads fail: reload this page, enable JavaScript, disable download managers, disable proxies, 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.

The binaries are built with Microsoft Visual Studio (2008 Professional or .NET 2003), Intel Compiler Suite 11, Windows SDK for Windows Server 2008, Windows Server 2003 R2 Platform SDK, MinGW, MinGW-w64, and the current official Python versions (with patch for issue 7833).

Many binaries depend on Numpy-MKL 1.6 and the Microsoft Visual C++ 2008 redistributable package, which may need to be installed separately for x64 and x86 architectures.

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.
