I was trying to play with PyMC3 and as per usual with code under heavy development the tutorials were out of date, and the code wouldn't run. When I say "out of date" in fact the code ran but no valid numbers were produced. The API seemed to be consistent though.
I managed to get the tutorial to run by installing the following:
Theano==0.6.0 pymc==3.0 scipy==0.13.3
PyMC3 was installed from git from the
pymc3 branch as follows:
pip install git+https://github.com/pymc-devs/pymc@pymc3
I had some trouble installing the
pymc3 branch without installing the specific version of Theano shown.
