_pickle.UnpicklingError: invalid load key, 'v'.

Hello! I think the error is caused while loading the model from pickle file. Because I have used git LFS to push large files, like models into github. I get error while unpickling and loading from that model in this step:

> trainer = restore_model(pkl, checkpoint, train)

File "/opt/app/inference_docker.py", line 253, in restore_model

> saved_model = torch.load(checkpoint, map_location=torch.device('cpu'))

File "/home/user/.local/lib/python3.10/site-packages/torch/serialization.py", line 1040, in load

> return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args)

File "/home/user/.local/lib/python3.10/site-packages/torch/serialization.py", line 1262, in _legacy_load

> magic_number = pickle_module.load(f, **pickle_load_args)

_pickle.UnpicklingError: invalid load key, 'v'.

I get okay results while I try to do it on my own computer. But again when I upload algorithm for inference I get this error. How to resolve?

This seems to be a problem with model downloading, which I do not have a direct solution for you. I would suggest you to try uploading a locally built container instead of linking a github repository, just to make sure the model files are correctly included.

Hello, I uploaded model files on drive and downloaded on docker container using gdown. It finally solved the issue, as the issue was caused by using git lfs during uploading model on github. Anyways thank you.
