Cookbook – Bayesian Modeling with PyMC3

gh02t · on June 21, 2018

Out of curiosity, what is the future of PyMC3 since development on Theano was halted? I used PyMC very extensively in my dissertation work (both 2 and 3) and even implemented some custom samplers for it, but when I heard the devs of Theano were stopping work I knew that was gonna be pretty problematic for PyMC at some point down the road.

A prototype for pymc4[0] is in the works, to be built on top of TensorFlow. There's also a Google Summer of Code student[1] assigned to the effort.

Looks like the PyMC maintainers are taking over Theano (but only as it helps PyMC): https://medium.com/@pymc_devs/theano-tensorflow-and-the-futu...

There is a PR to get TensorFlow as the backend for PyMC3 too.
