FileNotFoundError: [WinError 2] The system cannot find the file specified: '[...]\\comfyui_workflow_templates\\templates' #10674
Description
Custom Node Testing
- I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)
Expected Behavior
To be able to start ComfyUI server.
Actual Behavior
Starting main.py exits with error.
Steps to Reproduce
Before starting ComfyUI I ran pip list -o and I noticed there is an updated comfyui-workflow-templates package. I updated that and it also downloaded another similar named packages:
comfyui-workflow-templates-media-api 0.3.0
comfyui-workflow-templates-media-image 0.3.0
comfyui-workflow-templates-media-other 0.3.0
comfyui-workflow-templates-media-video 0.3.0
Also I ran a git pull from latest git in ComfyUI folder.
Then trying to run ComfyUI with my usual command exited immediately. I then moved all the custom nodes to the .disabled subfolder. Simply python.exe main.py without any arguments gives the error bellow:
