Unable to start ComfyUI Desktop v0.4.54

I downloaded Comfy to my Windows 10 PC. It gave me the following error: " Unable to start ComfyUI Desktop v0.4.54" Another window popped up saying Python exited with code 1 and signal null. How do I solve this so that I can use Comfy?

Same thing

I noticed there was a response in another post like mine where it said it doesn’t work for AMD GPUs, but I am using a Nvidia RTX 4060.

Got the correct Python version?

Installed the dependencies?

Dependencies

Install the dependencies by opening your terminal inside the ComfyUI folder and:

pip install -r requirements.txt

5

Dependencies installed. ComfUI itself is not installed. Trying to re-install it and there’s
Error invoking remote method ‘reinstall’: Error: ENOENT: no such file or directory, lstat ‘C:\Users\Ivan\AppData\Roaming\ComfyUI\extra_models_config.yaml’

The thing is I had a previous installation that I had to interrupt at some point. And after that it just doesn’t want to install.

Maybe try the standalone version?

The windows portable…

And it worked! Thank you so much!

I have Python 3.10. I tried running `pip install -r requirements.txt’, but it said it couldn’t find the requirements.txt file.

I tried running run_nvidia_gpu.bat but got

Not sure if the v3.10 is the problem, but according to the git page:

python 3.13 is supported but using 3.12 is recommended because some custom nodes and their dependencies might not support it yet.

If you run “pip install -r requirements.txt” be sure you are in the correct directory first. Check in your windows navigator where the requirements.txt is, in my case ../ComfyUI/ComfyUI/

ps. I think it better to not run it in the Downloads dir, could give so restrictions problems sometimes.

Thanks for pointing me in the right direction!! I went to chatgpt with the log. That interpreted the errors that I was having a problem with it didn’t see any cuda for pytorch. That brought me to the nvidia site to install them. Then I needed to run nvidia_gpu.bat which brought up the website. Then I reinstalled the local comfyui and it started!

Trying to reproduce the issue on our end.

Reproduced and have a fix on the way. In the meantime, can you delete this file? It will let you do a fresh install.

C:\Users\onlym\AppData\Roaming\ComfyUI\config.json

How can this problem be solved?

So I uninstalled from windows, and deleted the following folders:

C:\Users\Admin\AppData\Roaming\ComfyUI
C:\Users\Admin\AppData\Local\Programs@comfyorgcomfyui-electron
C:\Users\Admin\Documents\ComfyUI

This worked for me.

Continuing the discussion from Unable to start ComfyUI Desktop v0.4.54:I’d like to ask if you’ve resolved it? I added a new workflow today. After updating the new node, it started throwing errors when I accessed it again.
