Does pystan3 supports custom build/compile locations for its model cache

Hi,

httpstan (which does the caching) uses appdirs

stan-dev/httpstan/blob/09c0cf229fd3276babe262355155b95ed02d336f/httpstan/cache.py#L18


      
          from importlib.machinery import EXTENSION_SUFFIXES
          from pathlib import Path
          
          import appdirs
          
          import httpstan
          
          logger = logging.getLogger("httpstan")
          
          
          def cache_directory() -> Path:
              """Get httpstan cache path."""
              return Path(appdirs.user_cache_dir("httpstan", version=httpstan.__version__))
          
          
          def model_directory(model_name: str) -> Path:
              """Get the path to a model's directory. Directory may not exist."""
              model_id = model_name.split("/")[1]
              return cache_directory() / "models" / model_id

Then you can follow appdirs user_cache_dir logic.

                          appname = os.path.join(appname, version)
                      pathlist = [os.sep.join([x, appname]) for x in pathlist]
          
                  if multipath:
                      path = os.pathsep.join(pathlist)
                  else:
                      path = pathlist[0]
              return path
          
          
          def user_cache_dir(appname=None, appauthor=None, version=None, opinion=True):
              r"""Return full path to the user-specific cache dir for this application.
          
                  "appname" is the name of application.
                      If None, just the system directory is returned.
                  "appauthor" (only used on Windows) is the name of the
                      appauthor or distributing body for this application. Typically
                      it is the owning company name. This falls back to appname. You may
                      pass False to disable it.
                  "version" is an optional version path element to append to the
                      path. You might want to use this if you want multiple versions

Are you running on Linux or something else?
