PyPhi is a Python library for
calculating integrated information and its associated structures. It is
open-source and available on GitHub, and
can be installed on the command line with the Python package manager via
pip install pyphi.
The figures in the IIT 3.0 paper are illustrated with PyPhi as an IPython notebook and in the online documentation. This section is meant to serve as a companion to the paper, and readers are encouraged to follow along and analyze the systems shown in the figures in order to become more familiar with the theory and the software.
Please consult the the project's README for more information.
We have recently submitted a manuscript describing the software, a preprint of which is available on the arXiv:
Please cite the manuscript if you use PyPhi in your research.
