Black image output

Output on 6GB VRAM card is just an all-black image at 512x512 and 384x384.

Is the output fine at 256x256? If so, you probably don't have enough VRam to run the model at higher resolution; if you have multiple gpus, I am currently working on adding additional multi-gpu support.
Alternatively, I believe a lighter model will soon pop up in the open community and I could add that.
