I had run into the “Bad initial energy” error on a simple GLM model which I created. I decided to try out one of the official examples from the PyMC3 website ( https://docs.pymc.io/notebooks/GLM-logistic.html ) and I’m still getting this error.

I get "Bad initial energy" even on one of the examples

Try adding init='adapt_diag' when you call pm.sample.
