@michaelosthege thanks for the quick reply. I have good working installations for both Windows 8.1 and Ubuntu 20.04. Bambi is a really nice wrapper around Pymc3 to specify Fixed and Random effects with a formula specification. It emulates the Brms package in the R-Stan universe which simplifies hierarchical / multilevel model specification significantly for non-programmers such as myself.
I’m beginning to suspect the global compilers may be the issue as you pointed out. I use RStan and Greta in the R environment and compilation of RStan models is done with RTools which houses gcc-mingw compilers and they appear first in the path.
Is there a way to specify through named variable paths, the exact compilers Anaconda Python should be using? Thanks again for taking the time to help.
