How to specify number of threads in pystan3.7

Modeling

Hi! I am using pystan 3.7 to run a model with reduce_sum. I notice that there is no extra_compile_args argument in the compile function stan.build. Can anyone clarify how to use multiple threading in pystan 3.7? Thanks!

Have you found an answer to this question? I am in the same situation as described, and can’t find how to run multiple threads. Is moving to cmdstanpy the only way to run the model with multiple threads from Python?

Hi guys…I’m also trying to find the solution to multithread in pystan!

Here there is a code on how to do it with pystan 2:

But I cannot find the analogous for pystan3…

Thanks to whomever leaves a few guiding lines here…
