Images are blank

[daltonrooney]

I tried a text -> image prompt using the standard image settings, the image generated but is just a solid black PNG. Let me know where to find the logs and I will upload them. 14" Macbook Pro M1 with 16GB of RAM.

I suspect the NSFW filter is still on. Check your prompts

[BrianGilbert]

I get random black PNG's as well, on prompts that don't have any hint of NSFW

[daltonrooney]

It’s working for me if I reduce the images to 256px. Maybe a memory issue? I knew I should have gone for 64GB! 😭

[drewlustro]

Happens every other generation for me. Just try again!

@daltonrooney I'm on 14" Macbook Pro M1 Max with 16GB of RAM and it works fine at 512 x 512. Doubt it's a memory issue.

Might be worth quitting all other apps and/or restarting your machine to see if it helps

MBP 16" M1 Max with 32 GB of RAM on MacOS 12.6 and I still get black PNGs once in a while

[harryshawk]

I got a black image today as well.

I'm getting black images now too. NSFW filter isn't on - I've validated that

[elbowdonkey]

When I've seen this happen, it's usually when DiffusionBee is in the background and I'm doing something somewhat CPU heavy. I've not yet tried to tease apart why it happens, but that part at least feels consistent.

I've also seen this behavior at what seems like random times (2021 16" M1 MBP / 16gb). If I rerun the prompt it always works the second time, and the inputs were relatively benign so I doubt NSFW filter.

I just found this issue for another M1 capable fork of stable diffusion - might explain the black images.

@hellbox fancy meeting you here.

no, the "black images from k-diffusion" bug is different (it happened 100% of the time, not sporadically).

sporadic black images is something I'm aware of (which I noticed on PLMS sampler, at high numbers of steps):
invoke-ai/InvokeAI#517 (comment)
but haven't investigated, because the problem never happens to me any more. I use low step counts (e.g. 8), and k-diffusion samplers.

you can get good results in as few as 7 steps if you use the right sampler and noise schedule:

[masaldana2]

this I all I get every time

[ProStrike-hub]

I also have the same problem every time, even when I decrease steps to 10... So I doubt this is because of my computer's performance.

Couldn't locate this NSFW filter you're talking about.

Anyone has a fix please?
