Hm, pyyaml is already installed (in a directory of my Python installation. Requirement already satisfied: pyyaml in c:\users\dartha\appdata\local\programs\python\python312\lib\site-packages (6.0.2) I’ve since installed the non-desktop version of ComfyUI without problems. Then I’ve tried to reins…

It looks like the extra_models_config.yaml file, in %APPDATA%\ComfyUI is missing the trailing \ in the base_path: base_path: M:\ComfyUI base_path: M:\ComfyUI\
