@jessegrabowski I went through that env.yml and one by one matched the packages by downgrading packages in the fresh environment. That is how I found out that the open_blas and sqlite packages were the culprits. I don’t know if those specific versions of those packages set environment variables upon installation. When it comes to sampling speed, after downgrading those packages I get a wall time of around 2 mins and PyMC says that it took around 50 seconds to sample the model.
I am using a MacBook Pro with an M1 Pro cpu in it.
