[scorobetele]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

It generates black images. I have been trying to fix it for hours, but to no avail.

Steps to reproduce the problem

2. wait
3. cry because it generated a black image despite trying for several hours to fix it

What should have happened?

It should have generated an image, that is not black.

Additional information

I have an Nvidia 1660 Super GPU and I believe this is the source of the problem because it seems that 16xx GPUs have this bug, but unfortunately none of the fixes worked for me.

same error here. On using the finetuned safetensors. It either generated most random noise or dark greyish image, even on previously tested community models

Same here

Did any of you get this fixed? I'm facing the same issue. No matter what I prompt I just get noise back

In my case, above, the issue went away when i used --no-half on the M3 mac.
