Management of conflict between custom nodes

[John-Dormevil]

Expected Behavior

1. Install comfyui-easy-use, comfyui-kjnodes and comfyui-mvadapter with custom nodes manager.
2. Restart ComfyUI.
3. Attempt to use a workflow that utilizes functionality from all three custom nodes.
4. All three custom nodes should function correctly without version conflicts or errors.

Actual Behavior

• Comfyui-mvadapter is not properly load, and nodes is not available to use in workflow.
• Version conflicts for huggingface_hub prevent the proper loading of classes, causing errors and making workflows and nodes unusable.

Possible Solutions and Questions :

• Is there a recommended approach for managing shared dependencies between custom nodes in ComfyUI ?
• Should there be a convention or standard for specifying dependency versions in custom nodes ?
• Could a virtual environment for each custom node be a solution?
• Should ComfyUI implement a way to manage custom node dependencies?

Thank you for your assistance.

Steps to Reproduce

1. Install comfyui-easy-use, comfyui-kjnodes and comfyui-mvadapter with custom nodes manager.
2. Restart ComfyUI.
3. Check the log and Attempt to use a workflow that utilizes functionality from all three custom nodes.
4. Observe the class loading errors related to huggingface_hub.errors.

Version conflicts in huggingface_hub.errors prevent the proper loading of classes, causing errors and making workflows and nodes unusable.

Each of these custom nodes depends on the huggingface_hub Python package, but they seem to require different versions. This results in class loading errors, as a class expected by one node might not be available in the huggingface_hub version installed to satisfy another node's dependency.

Example of Error: ImportError: cannot import name 'LocalEntryNotFoundError' from 'huggingface_hub.errors

Work around:

Force in all requirement.txt, huggingface_hub to the lastest version.
Remove in .venv huggingface_hub dependencies

Restart ComfyUI now nodes should be properly loaded.

The culprit here is the Comfyui-mvadapter requirements:
https://github.com/huanngzh/ComfyUI-MVAdapter/blob/main/requirements.txt

Some dependencies are set to a specific version, like: huggingface_hub==0.24.6

KJNodes and Easy Use are good.
