Question about generate_celeba_synthesize() func in data_loading.py

[BostonLobster]

Hi~
In generate_celeba_synthesize from data_loading.py(here), you just applied denorm on predicted_normal, but others are ignored.

Could you explain a little bit about why? I know the input face is in range [0~1], but why does the predicted_normal become [-1~1]?
