I have issue with using cv2 at streamlit

Question

I create app usig streamlit that enable user to scan QR code via camera. The app is work very well locally but when I uploaded it to GitHub and deploy at streamlit community cloud I get this error on app page:

File "/home/appuser/venv/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 534, in _run_script
    exec(code, module.__dict__)
File "/app/path.py", line 4, in <module>
    import cv2

and this error on log file: File "/app/path.py", line 4, in

import cv2

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

I tried to add opencv-python at requirements.txt file but it's still occure.
