Hi everyone,

I was trying to install pystan but see the following errors, does anyone know why? Thanks!

Windows is not currently supported for PyStan, can you use CmdStanPy or Linux (e.g. WSL)

Thanks. Yes I may try CmdStanPy instead–does it have the similar functions like rstan?

What functionality do you need?

Most part yes (it calls cmdstan) but it is missing logp caller.

Just some regular functions–should be good. Thanks!
