ONNX conversion notebook is broken

[arsenyinfo]

The conversion notebook is currently broken because download_checkpoints.sh fetches newer 2.1 weights.

FileNotFoundError: [Errno 2] No such file or directory: 'checkpoints/sam2_hiera_base_plus.pt'

The simplest workaround is to uncomment old checkpoints and comment new ones in the download_ckpts.sh.

I think having the converted weights as part of the repo would be very suitable.

You need to slightly update the notebook.

Here is the updated notebook for 2.1 :
