Excessive memory usage in PyMC3? (Solved - AWS Linux platform issue. Works on AWS Windows)

Hello,

It’s Theano 0.9.0, PyMC3 3.2.

It’s running CPU only (as the AWS instance I am currently using does not have a GPU). I can move to a GPU instance if that is a problem. (But the issue isn’t execution speed, it’s memory usage).

Thanks!
