Error When Running preprocess_may.sh: Empty Image in 'imwrite' Function

[aomenfage]

Hello,

I encountered an error while running the preprocess_may.sh script from this repository. The script failed with the following error message:

../dataset/may/images/06073.jpg
OpenCV(4.4.0) /tmp/pip-req-build-19zx5q4j/opencv/modules/imgcodecs/src/loadsave.cpp:738: error: (-215:Assertion failed) !_img.empty() in function 'imwrite'

This suggests that the image being processed is empty or corrupted in the crop_face.py file, leading to failure in the imwrite function of OpenCV.
Could you please help in diagnosing the problem? Any suggestions on how to handle or debug this error would be greatly appreciated.

Thank you!
