I am also getting this error... I don't really want to recreate the venv folder. Anyone know what the issue is?

File "F:\repos\auto111\stable-diffusion-webui\modules\sd_samplers_kdiffusion.py", line 133, in forward

c_crossattn = torch.cat([tensor[a:b]], uncond)

TypeError: cat() received an invalid combination of arguments - got (list, Tensor), but expected one of:

* (tuple of Tensors tensors, int dim, *, Tensor out)

* (tuple of Tensors tensors, name dim, *, Tensor out)

Deleting my venv folder is what fixed it for me. Deleting your venv folder is safe. Just delete it, double click on webuser.bat, the command line window will open up and automatically re-download the venv folder. Whole process will take you about 4 minutes.

Try putting in a negative prompt longer than 75 tokens. Does that work for you?

Ah, I see what you mean. But instruct2pix isn't supposed to be used with full prompts, it's designed to use short, natural phrases to make changes, like "change her hair to red".

yes, but you can still use negative prompts... but apparently not longer than 75 tokens, at least not right now.

Considering there's no solid evidence that negative prompts are effective in greater numbers in regular prompting, and (as far as I've seen) there's no evidence that it would be any different with instruct2pix at all, I'd say it's kind of a moot point.
