Original GitHub issue: https://github.com/Comfy-Org/ComfyUI-Manager/issues/649

I'm trying to enable ComfyUI in Google Colab
I went to the link
Notepad Colab
https://colab.research.google.com/github/ltdrdata/ComfyUI-Manager/blob/main/notebooks/comfyui_colab_with_manager.ipynb

I'm launching "Run ComfyUI with localtunnel"
and then the error appears

/tools/node/bin/lt -> /tools/node/lib/node_modules/localtunnel/bin/lt.js

localtunnel@2.0.2
added 22 packages from 22 contributors in 2.279s
python3: can't open file '/content/main.py': [Errno 2] No such file or directory

the first time I logged into ComfyUI, the second time it gives an error, oddly enough, but I have the main.py file

it happened that I went into ComfyUI but there was a 404 error on the screen

in 99% of cases it gives an error, and in 1% you can go to ComfyUI

I also chose the second option
"Launch ComfyUI using iframe colab (use only if the previous method with localtunnel does not work)" and still an error

python3: can't open file '/content/main.py': [Errno 2] No such file or directory

Help please (0 - 0)

try instead of main.py to use your mounted google drive path were the main.py for example:
!python /content/drive/MyDrive/ComfyUI/main.py --dont-print-server --highvram

good luck
