It seems the Dirichlet distribution is not working in v 4.0.0b3 yet, although I cannot find anything about it in the release notes. Since mixture distributions have been implemented and there seem to be working examples in the new doc, I thought this already worked once. Is this a known WIP or a pro…

I was able to solve the issue by removing this option from my ~/.aesararc: [global] optimizer = fast_compile

Quite surprising error. The Dirichlet has been refactored a long time ago and its used in several tests. I haven’t seen any issues with it.
