PSNR and max_diff_nll for different τ values #4

Hello, I would like to ask why psnr will become smaller with the decrease of τ value, while max_diff_nll value remains at about 50, which does not become smaller. image

Hi there, I think your code might be running incorrectly. When $\tau=0$, there should be no loss, PSNR should be infinite, and max_diff should be $0$. Something seems to be off here. Could you check if your experimental environment matches the recommended one, such as the PyTorch and CUDA versions?
