OpenCV issue windows X64

[DBonbon]

I hope you could help me with a Python error message I didn't manage to resolve.

I followed your steps and had the following error message:

File "C:\Users\yrfri\Documents\Blender\vincent facial mocap\Vincent(1).blend\OpenCVAnimOperator.py", line 30, in
File "C:\Users\yrfri\Documents\Blender\vincent facial mocap\Vincent(1).blend\OpenCVAnimOperator.py", line 43, in OpenCVAnimOperator
cv2.error: OpenCV(4.5.1) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-r2ue8w6k\opencv_contrib\modules\face\src\facemarkLBF.cpp:487: error: (-5:Bad argument) No valid input file was given, please check the given filename. in function 'cv::face::FacemarkLBFImpl::loadModel'

I'm using Blender 2.91, Python 3.9 on my computer and Python 3.77 for Blender. I tried the Blender Python version to run promlt as administrator.

Here is what I tried to do in order to resolve the issue:

• Updated or re-installed all applications (python, Blender...)

• followed the exchange on your Youtube:

• tried path name with \, /, "", '',

• tried to modify: self._cap = cv2.VideoCapture(0) into (1) and back to the original script.

• verified that the file size is 55.5MP

The error message is the same.
Any input would be highly appreciated, I',m really wish to experience this facial mocap.
