scipy-weave provides tools for including C/C++ code within Python code. Inlining C/C++ code within Python generally results in speedups of 1.5x to 30x over algorithms written in pure Python.

scipy-weave is the stand-alone version of the removed SciPy submodule scipy.weave. It is provided for users that need versions of SciPy from which the weave submodule has been removed but have existing code that still depends on scipy.weave. For new code, users are recommended to use Cython.

Note that the Python 3.x support is new as of version 0.19.0 (Nov 2022), and is experimental. It is not tested on all Python 3.x versions. For Python 2.6-2.7, use versions 0.17.0 or 0.18.0

To install scipy-weave, use of pip is recommended:

pip install scipy-weave

Note that the import name for scipy-weave is weave. To run the tests:

python -c "import weave; weave.test('full')"
