Bug with loading a lora

[cchance27]

Whenever I try to load a lora when it gets to the sampler I get an error....

Yes, there's a new required package (peft backend). Please run pip install -r requirements.txt to install the packages. This should solve this issue.

BTW, I believe that there can potentially be more people with such problem. May I ask how you updated the repo? Did you use the manager or manually execute 'git pull'?

[cchance27]

i had installed from git, i'll try with an updated requirement pull and install

[cchance27]

that seemed to work me past this specfic error closing this

I just ran into this same issue, though been updating CoreMLSuite through ComfyUI Manager. I originally installed from GIT; pip install -r requirements.txt resolved it for me.

I only just started testing out loading LORAs.
