After updating the latest ComfyUI, an error occurred.

This is a result of the comfyUI change made a few days ago removing the "CompVisVDenoiser" you can view the changes in the commit here

How to solve it?

[JAssertz]

Currently toxicwind has a fork open that should allow it to work the other option is to re-add the missing section of code to the updated file.

If it won't be a trouble for you, would you mind to write how we can do that, please?

Switching forks in git:

cd ComfyUI/custom_nodes/efficiency-nodes-comfyui`
git remote add toxicwind https://github.com/toxicwind/efficiency-nodes-comfyui-updates.git
git fetch toxicwind
git checkout toxicwind/main

note: this is a detached head; if you wanted to resolve, git checkout -b some_interesting_named_branch -- I just leave it, since this is just temporary

Later, presumably when "this" efficiency-nodes does an update:

git fetch origin
git checkout main
git pull
git remote remove toxicwind

That fork gives me the following error, which has been fixed this fork. Use toxicwind's repo at your own risk; still hoping this issue gets some attention.

This commit brings the removed code back over. Works for me, and prods' branch also fixes the above issue as well.

I can confirm that repo fixes the CompVisVDenoiser error from original extension.

However I had to fix all my efficient node values because with this version, all values were displaced from their original input boxes.
