issues Can't get attribute '__main__'

[mdandre89]

I am using virtualenv and tried diff combinations of torch and fastai but always get errors.

EDIT: Sorry most likely solved. I was trying to open a model saved with fastai 1 with fastai2, but there still issues with this:

AttributeError: Can't get attribute 'label_func' on <module 'mp_main' from '/home/mdandre/projects/data_science/skin_cancer_prediction/backend_skin_cancer_prediction/bin/uvicorn'>

and once I try using dill to save the environment:
AttributeError: Can't get attribute 'main' on <module 'builtins' (built-in)>
