Hi. I am working on paper on post inference prior swapping to predict the year of song using bayesian linear regression. Initially i am using prior as normal model and trying to compute posterior based on the data. ‘Year ~ F1 + F6 + F3 + F63 + F40 + F7’ . This are the features. Context for the mo…

Yeah that’s what I thought: something made initialization much more sensitive on the master branch, causing ValueError: Mass matrix contains zeros on the diagonal to appear more frequently. On this version, can you try: normal_trace = pm.sample(init="adapt_diag") More informative priors. I think …
