When saving large graph, creating a temporary folder will cause the system disk resources to be exhausted.

with tempfile.TemporaryDirectory() as temp_dir:
    joblib.dump(self, os.path.join(temp_dir, self.f_model), compress=True)
    with open(os.path.join(temp_dir, self.f_mdata), 'w') as f:
        json.dump(meta_data, f)
    filename = shutil.make_archive(filename, 'zip', temp_dir)

It should be written directly to the destination.
