@rosgori thanks for the link. That was the first resource I had examined thoroughly to see how the errors can be corrected. I followed the specific installation instructions and that helped me run the Linear Regression and Stock Market examples provided in the “Pymc3 Getting Started” page. I was using the example code verbatim.
The error occurs again in the third example “Coal Mine Disasters” model. My code shows that Pymc3 is correctly assigning NUTS for Continuous variables and Metropolis for the Discrete (the Count of Coal mine accidents) but yet the error crops up. I have removed the environment and reinstalled per the specifications given in the link you shared. The error does not go away.
Could you try to replicate the Coal Mine disasters example given at this link and see if you are able to replicate the error I’m getting? See the link below
