Hi @ricardoV94, I can confirm the code in Lkjcorr returning error - #17 by mcao as well as batching the dims in MvNormal works on my personal computer by pip installing the latest pytensor (version 2.18.3).
p.s. I haven’t tried conda/mamba in my work environment yet. I’ll mark this topic as solved since the issue is related to the work computer settings.
