[Python] pyinstaller + docker + openCV

I am trying to use pyinstaller to package a simple python script that imports cv2 module and all this should be done inside a docker container (this is part of a Gitlab CI/CD pipeline).

I think I am doing this right in the right order, i.e.

• start a docker python image,
• then I can run apt-get install -y python3-opencv
• pip install opencv-python
• pip install pyinstaller
• pyinstaller -F sample.py

sample.py can be

import cv2
print("hello")


When I run the resulting executable I get the error: ImportError: libGL.so.1: cannot open shared object file: No such file or directory

I've tried locating this library and adding to --paths option for pyinstaller but iwht no luck. Any help is appreciated
