We can use this notebook I found online, which also doesn’t work: https://github.com/WillKoehrsen/Data-Analysis/blob/master/bayesian_lr/Bayesian%20Linear%20Regression%20Project.ipynb (cells 39-40)
By ‘sampler doesn’t start’ I mean it’s forever frozen at this screen:
So nothing really happened actually. I was running a model on 4 chains, 8 cores, target_accept=.9 because I was following this tutorial here (https://docs.pymc.io/notebooks/Diagnosing_biased_Inference_with_Divergences.html ), but it was 2 am so I went to sleep after the model finished running, and then the next day (without even restarting the jupyter kernel, it didn’t work anymore - by didn’t work I mean the sampled wouldn’t start like in the image above).
Anyway, I suspected I had some memory issues, or there were other processes running on my computer so I closed everything, restarted everything and at some point attempted reinstalling pymc over pip (just like it was installed originally).
