Changing the location of caching models/results of Stan

hahawalk · November 15, 2022, 4:44pm

Hi,

I run pyStan model on a server. And I have a question about setting the directory where the cached model and results are saved.
I used the following command to specify the cached model on a project space. But it is still saving the cached model in its default folder. Am I writing anywhere wrong or missing anything? Thanks!
XDG_CACHE_HOME=/project/mutsigs/pythonlibs/lib/python3.8/site-packages/.cache/

Your server is running linux?

github.com

ActiveState/appdirs/blob/193a2cbba58cce2542882fcedd0e49f6763672ed/appdirs.py#L264


      
                          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

Test what appdata sees.

Also make sure that os.environ sees your path

Yeah, it is linux. Do you mean in my python script, I add print(stan.user_cache_dir() ) to check the cache_dir?

Yeah, I would start debugging there.
