You get that error because the dataloader has to return something. Here are three solutions:

1. There is a libary called nonechucks which lets you create dataloaders in which you can skip samples.

3. You could return some indicator that the sample is unwanted, for example

if"y":
    return data, target
else:
    return -1

And then you could check in your train loop if the "data" is -1 and skip the iteration. I hope this was helpful :)
