PyPI version Travis-CI Appveyor Codecov License: MIT is a lean persistent homology package for Python. Building on the blazing fast C++ Ripser package as the core computational engine, provides an intuitive interface for

  • computing persistence cohomology of sparse and dense data sets,
  • visualizing persistence diagrams,
  • computing lowerstar filtrations on images, and
  • computing representative cochains.

Additionally, through extensive testing and continuous integration, is easy to install on Mac, Linux, and Windows platforms.

We supply a large set of interactive notebooks that demonstrate how to take advantage of all the features available.

You can find the source code on github at Scikit-TDA/ For the original C++ library, see Ripser/ripser.
