 Description:
BayesPy provides tools for variational Bayesian inference in Python. The model is constructed as a Bayesian network. The aim is to provide a tool which is efficient, flexible and extendable enough for expert use but also accessible for more casual users.
Documentation: http://bayespy.org
Repository: https://github.com/bayespy/bayespy
 Changes to previous version:
 Fix normalization of categorical Markov chain probabilities (fixes HMM demo)
 Fix initialization from parameter values
