[Bug]: Negation Prompts -- AND NOT operator
Is there an existing issue for this?
- [X] I have searched the existing issues and checked the recent builds/commits
What happened?
as a user when I enter the prompt a guitar AND NOT brown
I still get a brown guitar
if I put brown in the negative prompt, I do not get a brown guitar. the negative prompt is working.
Steps to reproduce the problem
enter the prompt a guitar AND NOT brown
I still get a brown guitar
if I put brown in the negative prompt, I do not get a brown guitar. the negative prompt is working.
What should have happened?
when I put AND NOT it does not work.
Commit where the problem happens

I think the NOT operator doesn't exist in this repos. Its function is taken care of by negative prompt as you saw yourself. Am I wrong ?
You are correct, the negative prompt does work, however, the expectation would be that AND NOT would also function.
Consider the "read generation parameters from prompt button" parses things from the prompt, but not AND NOTs.
This should function, to be a complete implementation.

Auto's comment: https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/1695
I disagree with auto's assertion that it "seems" redundant because we have weights.
Yes, lets use weights instead of natural language, because it... checks notes adds to the complexity?
Leaving it as is causes a crash when DDIM sampler is selected.
If you believe that negative prompts are the solution then convert the AND NOTs in the prompts to negative when you use the "read generation parameters from prompt button" is pressed.
should I open a feature request to get a crash report fixed?

I don't think these are the same. I think the only things from compositional diffusion paper is the AND operator, and weights
a photo of a mountain AND a photo of a tunnel
I believe you can combine multiples:
a photo of a mountain AND a photo of a tunnel AND a photo of a gym
You can also add weights, you might have seen some custom scripts (prompt morph, prompt interpolation) that use this.
a photo of a mountain:0.5 AND a photo of a tunnel:0.7 AND a photo of a gym:0.3
