Black Image for fake_sample.png at scale 8 and 9

[J0rmel]

Hello, sorry for my english because I'm french but I have an unexplained issue for me. When I execute this line :
python main_train.py --input_name colusseum.png for example, I have some black image generated for fake_sample.png and G(z_opt).png for scale 8 and 9 for example and I don't understand why. It's the same when I try every other function like random sapling or SR, I have black image

I have RTX 3080 TI and I use python 3.6, torch 1.4.0 and torchvision 0.5.0.
