[wwwWolfcom]

Is there an existing issue for this?

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

What happened?

Same prompt,seed,checkpoint,ensd,eat,sigma noise etc. Gives different output.

Here is the examples. Should be: But gives:

as you can see, big parts are similar(arrangements,shape) but detailed parts are cleary different. Funny thing is, it happens randomly every time start colab. Not in the middle of running. Sometimes it generates original outputs. But sometimes(restart colab after 1 minute to day dosent matter)generates different outputs. It's not the level of xformers indeterminate. IIt's not original VS worse variations. It's like 50:50; original output VS worse output(no variations. only 1 output) older commit didnt fixed the issue.

Steps to reproduce the problem

1. start colab
2. wait for setup
3. starts webui

Maybe i don't understand something, but isn't it because of xformers?

As far as i know xformers speed things up, but make everything random

I know that with xformers there is randomness. However, even if you use xformers, the most elements should stay similar. Differences should be subtle even i use xformers, like buttons or hair are normal. In this case, there is a difference in quality that goes far beyond that.

What sampler is being used.. ancestral samplers give different results with the same seed majority of the time (especially with xformers enabled)
