Hi,
After a Mac update I am unable to run a certain model.
I tried to create a new conda environment and re-installed Stan as follows
python3 -m pip install pystan
but the problem still occurred.
I ran the standard “hello-world” example and this worked as expected.
However, if I I try to compile and run the second model I am getting the following error:

I believe that the problem is located in
subprocess.TimeoutExpired: Command ‘[PosixPath(’/Users/User/opt/anaconda3/envs/ufc/lib/python3.10/site-packages/httpstan/stanc’), ‘–name’, ‘model_lvfvy52u’, ‘–warn-pedantic’, ‘–print-cpp’, ‘/var/folders/dp/f415vsl54j3gxzlnnbndwsq40000gn/T/httpstan_b7n0tb55/model_lvfvy52u.stan’]’ timed out after 1 seconds
If I inspect this directory I see that the directory “httpstan_b7n0tb55” doesn’t exists.
The “hello-world”-model is found in the cache directory after compiling. I deleted all the cached models from the following location:
from pathlib import Path
def cache_directory() -> Path:
"""Get httpstan cache path."""
return Path(appdirs.user_cache_dir("httpstan", version=httpstan.__version__))
print(cache_directory())
>>/Users/user/Library/Caches/httpstan/4.13.0
Any idea why httpstan is for the “hello-world” script checking the cache directory and, if not found compiling it, whereas it checks a different non-exisiting directory for the other model and giving an error?
Help is much appreciated!
