This issue just happend today. I noticed there were similar issues here, but my case is with ModuleNotFoundError: No module named 'ultralytics' I re-installed ComfyUI with only Impact-Pack custome node with ComfyUI-Manager. Clean install but still the same issue occurs. Any help will be greatly appreciated. I am using the Colab notebook included in the ComfyUI Manager repo. Below is the error messages...

No module named 'ultralytics'

If I try to fix it in the Manager, it says "security level configuration" 1 2

Actually, it works at first but if I restart Colab and then the Import Failed issues occurs with the error message. it seems that the "ultralytics" module is installed when "Impact Pack" is installed, but the module is uninstalled afterward.

I manually installed "ultralytics" and restarted. It works. No errors. However, if I disconned Colab and open the note again, "ultralytics" is missing. I wonder if I should manually include "ultralytics" in the requirements.txt so that it is properly installed.

UPDATE I additionally installed the ComfyUI-YOLO custom node as it includes "ultralytics" in the requirements.txt file. It guarantees that "ultralytics" is always available on Colab. Butl, I am worried what if ComfyUI-Impact-Pack is installed before ComfyUI-YOLO and fails.

oh... I got it... What is the situation.

It appears that Colab does not install the ultralytics module by default. When I install the ComfyUI-Impact-Pack and restart while Colab remains connected, ultralytics is present in the environment, and no error occurs. However, if I restart Colab after disconnecting, ultralytics is missing. I believe this happens because ultralytics isn’t included in the requirements.txt file and isn’t installed by Colab automatically.

To address this, I install ComfyUI-YOLO since ultralytics is listed in its requirements.txt. Ideally, ultralytics would be added to the main requirements.txt file of the ComfyUI-Impact-Pack for consistency.

I plan to separate Impact Subpack into a completely independent installation soon or later. When that happens, it will resolve itself naturally.
