Running this model with Pymc4 leads to an initialization error. It seems that large values from LogNormal overflow to infinity. If I change LogNormal to smaller values like ~1-5, then it works. Interestingly,running the same model with Stan works fine. Any idea why this is happening? Is this a over…
