Fix: "cut" parameter not passed to vision_learner

Fix #4027

[jph00]

Thanks! Note that this is an nbdev project so the source notebook needs to be edited -- that's the actual "source code" of the project.

[adamamer20]

Very interesting concept! I tried updating the notebook and exporting but i'm getting the same issue as fastai/nbdev#1056

AttributeError: 'list' object has no attribute 'lower'

Apparently this is given by nm=['Tensor.save_jpg', 'DcmDataset.save_jpg']. Happens both when executing the export inside the notebook and from the commandline. Hooks are installed and I made no other changes to the library. nbdev is 2.2.10 from conda-forge. Should i open an issue on nbdev?

[jph00]

You'll need to use WSL, not native Windows.

[adamamer20]

Thank you for the input. I tried on WSL and still having the same error.
