Training issue

Hi, the import errors are just warnings and that's OK. For the second error, I think the reason is that you didn't generate the occupancy data or the occupancy data is broken. You can follow here to regenerate the occupancy data.

Thanks for your reply. that's very helpful
I have followed the instruction to generate the occupancy data.
I changed the value of num_worker (data loader) to 1. The error is gone.
I think it might be the multiprocessing issue for the dataloder.

Not sure why that happens. But good to know it works at the end😊.
