Why drop_last of DataLoader is disabled

[RuiLiFeng]

I cut the num_works to 0 due to lack of RAM and run BigGAN_bs256x8.sh, ended up with error bellow

I noticed that it was processing the last batch in the first epoch, so I dug into the dataloader part, and I found that drop_last is disabled when use_multiepoch_sampler is enabled, would that cause tuple error as I meet?

Also could the authors be so nice to offer pretrained biggan deep?

I also encountered this bug after modifying the batch size. You can either set drop_last = True, or increase the num_epoch so it won't come across the last batch of data.
