Thanks, Lucianopaz and RicardoV94 for your help. I was hoping it wasn’t a vscode issue but that seems to confirm it.
Based on your last paragraph I went through and completely deleted vscode. Now pymc seems to import fine 
. I really appreciate both of your help during this.
I have tested it and have successfully been able to finish one the the pymc GLM module. It seems i get a broken pipe error when I try and idata = sample(3000) without setting cores=1 but this seems to be a common issue (here, here). Ideally, I would like multiprocessing to work but I think at this point I’ll just take a working package to be a win!
I appreciate all the help, if I cannot find a way to get multiprocessing to work on this MacBook would the team suggest I create another question here on the discourse forum?
Thanks,
Andrew
