When I ran train.py, I got the error. Who knows why and how to solve it?

[smartparrot]

I figured it out. Some images in my data is wrong, num_workers should be 0 in dataloader parameters.

I already set num_workers=0, and I've checked my data as well. There is no error. Could it be the problem of env?
