confused about the training input range

[zxcvads]

hi ,i have a question about the input dataset range ,i have see your paper released model input range is(0,256),if i change the input range to(-1,1) or (0,1)，i am confused about the PSNR change ,can you have a try in different training data range ?

It's not substantial. Some hyper parameters (such as learning rate) may need to be tuned according to data range.

No specific reason. Some legacy code use (0, 256).
Using (0, 1) is OK and can reach the comparable PSNR.
