Thanks, but I got this:

/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'main.py': [Errno 2] No such file or directory

Did I miss something?

[jaekr84]

open you terminal and white cd [drag your ComfyUI folder] and run with main.py --force-fp16 --use-split-cross-attention --cpu

Thanks, but it said "no such file or directory"... Should I install or put anything in that folder in advance?
