In 1.8.0 is not possible create the difference from two models

[DavideAlidosi]

I am trying to make the difference between two SDXL models but with WebUI 1.8.0 it seems to be not possible.
This is my workflow:

1. I select Difference between base and current.
2. I load the two models
3. I enable without LoRAs.
4. I name the new LoRA.
5. I press save

In case it is a LyCORIS I get the following error:
No lycoris module found No module named 'diffusers'
In the case of a LoRA
No scripts.kohya.* modules found. ERROR: No module named 'diffusers'

On 1.7.0 I have no errors at all.

I've found a fix, just need to copy system\python\Lib\site-packages\diffusers folder from 1.7.0 to 1.8.0 installation.
Probably just need to update this dependency into a new commit.
Bests.

yes. diffusers needed to use Lycoris/LoRA extractor. but diffusers dependency is not included in the requirements.txt or install.py for some reason. (diffusers used by many other webui-extensions but the versions are not exactly matched so I did not include diffusers in the requirements.txt and this is undocumented.)
thanks for your reporting!
