cmdstanpy: Unable to build Stan model

Summary:

Please provide a short couple sentence summary.

Hi,

I have been attempting to build a Stan model on an M1 Mac. Unfortunately, every time I try to build I get a message asking to rebuild cmdstan. Rebuilding is successful and results in the same error upon trying to build the Stan model again.

Description:

Describe the issue as clearly as possible.

Previously, I encountered errors such as mentioned in this ticket. I was able to successfully install cmdstanpy via conda and rebuild cmdstan:

>>> cmdstanpy.rebuild_cmdstan()
Done:  (01:14) | ███████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████ | --- CmdStan v2.29.2 built ---
>>> exit()
INFO:cmdstanpy:deleting tmpfiles dir: /var/folders/20/d05_tk914m3ft933jzk_rmnw81m0nb/T/tmpoq35v7ht
INFO:cmdstanpy:done

And now, I am still getting the PCH file warning when trying to build my Stan model.

python 02_CmdStan_Fit.py

The Stan model does build through pystan. Unfortunately with pystan, I get a vague initialization failed error when I try to sample, but I think that’s an unrelated issue.

Additional Information:

Here is the output from conda info if it is useful:
