        This probably means that you are not using fork to start your

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

 

{X = dataloaders: torch.utils.data.DataLoader (image_datasets [X], the batch_size = opt.batchsize,
shuffle = False, num_workers = 0) in X for
reasons: the need to run multiple processes in the main function,

Solution 1:

Plus main function call in main

Solution 2:

num_workers to 0, the process of loading a single
