The same here:

Not sure what I've changed, the day before it was working ok. I think it started after I've installed Real-ESRGAN.

Anyone managed to find a solution? I'm having the same issue, but no Real-ESRGAN installed. I had a problem with blank green screen generation in Stable Diffusion, that was related to fp16 not working on my 1660 Ti, could this be something similar? And if so, does anyone know how to switch to fp32 (if this is even relevant at all)?

I got this problem too after setting up my environment with CUDA "properly" so that torch detected it. I have a GTX 1650 with 4GB VRAM.

I was able to fix this by editing inference_gfpgan.py and setting half=False with RealESRGANer, so it is probably like the issue with --fp32 in SD.

            bg_upsampler = RealESRGANer(
                scale=2,
                model_path='https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.1/RealESRGAN_x2plus.pth',
                model=model,
                tile=args.bg_tile,
                tile_pad=10,
                pre_pad=0,
                half=False)  # <-- Set to False instead of True

@RupertAvery Worked perfectly on my GTX 1650- I thought I'd installed pytorch incorrectly. Thank you SO much!

Got the same problem with only black spot on the face
UPDATE- Solved by putting down the image from 16-bit to 8 bits/channel

You've been a great help — thank you from the bottom of my heart.
