Why does this error still occur when I use the lits dataset

Thank you very much for sharing SegAN. Currently, I apply the SegAN to segment the rib. If I use the Unet with the resnet as the backbone, the dice can achieve 0.85. But for SegAN, I can only obtain dice of 0.7. Do you have any suggestion?
could you share your code for me？I can‘t run this code，the code can’t open .nii file.
