WARNING: some comfy_extras/ nodes did not import correctly. This may be because they are missing some dependencies.

IMPORT FAILED: nodes_video_model.py
IMPORT FAILED: nodes_model_merging_model_specific.py

This issue might be caused by new missing dependencies added the last time you updated ComfyUI.
Please do a: pip install -r requirements.txt

pip install -r requirements.txt doesn't help. After I added an empty __init__.py in comfy_extras, it works again. Is this the right way to solve it? Or did I miss something?
