Seconding this as another WinOS user having issues with the pymc3 install, even after creating a new environment and following the instructions on Git step-by-step.
Seems like WinOS users have trouble 1. using multiprocessing and 2. linking Theano with the proper BLAS setup (e.g. defaults to Numpy C-API implementation)
A separate but related thread that sites the same “can’t pickle fortran objects” issue links to a website explaining how users can install Ubuntu in their WinOS environment and use pymc3 that way.
That might work for some people, but ideally a fix for WinOS would be better.
