ValueError of train_Mask-ShadowGAN

[Arican-Lee]

when I ran the test.py .There it is “FileNotFoundError: [Errno 2] No such file or directory: 'output/netG_A2B.pth' ”
So I went to run the train_Mask-ShadowGAN.py,and I also used the dataset of shadow_USR. However it happened ValueError: num_samples should be a positive integer value, but got num_samples=0.I've racked my brains. Is there any other way? Could you help me?
