The original object can be retrieved by calling the reference object if the referent is still alive; if the referent is no longer alive, calling the reference object will cause None to be returned. ``` However, it fails right at the end when I try to load the pyfunc model using mlflow.pyfunc.load_model The specific error is AttributeError: 'Model' object has no attribute 'load_model' which is strange because I'm calling the entire class mlflow.pyfunc.load_model. The root of the problem is that the `start` method of a `multiprocessing.Process` instance sets its `_popen` instance attribute to a `multiprocessing.popen_*.Popen` instance. here the model is built via a specific Project_id. I know it is beacause the 'env' I created is weakref, so I got such error when I run multiprocessing program. to your account.
