Welcome to kwarray’s documentation!

The kwarray module implements a small set of pure-python extensions to numpy and torch along with a few select algorithms. Each module contains module level docstring that gives a rough idea of the utilities in each module, and each function or class itself contains a docstring with more details and examples.

KWarray is part of Kitware’s computer vision Python suite:
