When I run the pix2pix GAN which implemented by eriklindernoren  in the Pytorch version 0.4.1, I got the RuntimeError as:
Exception ignored in: <bound method _DataLoaderIter.__del__ of <torch.utils.data.dataloader._DataLoaderIter object at 0x7f0f8f5490b8>>

Why encounter the error? Anyone can help me?
