How to solve this problem in Linux system?

Yep. Spent most of a day trying to fix this, even with the help of many coding AIs and no dice.

Tried:

Hardcoding the provider to CPUExecutionProvider for testing.
Renaming models, trying different folders.
Even just trying to run the base run.py command in terminal like this (and other variations with and without flags and switches), with and without .onnx extensions.

python ./run.py \
  --frame-processors        face_swapper \
  -s ~/AI/ComfyUI/output/deepfuze_00030_.png \
  -t  ~/AI/ComfyUI/output/deepfuze_00030.mp4 \
  --face-detector-model     retinaface_10g \
  --face-landmark-model     face_landmarker_68_5 \
  --face-swapper-model      inswapper_128 \
  --reference-face-position 0 \
  --face-mask-padding       0 0 0 0 \
  --headless \
  --execution-providers     CPUExecutionProvider

Not matter what the case, either inside Comfy with various settings and inputs and models, or via python direct, it always quits with....

[DEEPFUZE.PROCESSORS.FRAME.CORE] Frame processor face_swapper could not be loaded.

(which is the precursor to <whatever.mp4> could not be loaded with cv.")

Ok this is all about missing models. See the last PR and apply it.
