Do you know how to solve it? I have the same problem. Thank you.

bumping up! Having same issue here. It's not something super problematic, but makes me curious

it is due to the fade in feature of stylegan, you need to keep track the latest alpha for resume training. normally the alpha will be equal to 1 if you completed the training properly. you may try changing the code of <models/GAN.py> <line 753>

alpha = ticker / fade_point if ticker <= fade_point else 1 to alpha = 1
