Traceback (most recent call last):
  File "/home/adminuser/venv/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 534, in _run_script
    exec(code, module.__dict__)
  File "/mount/src/photo-editor-with-opencv/editor_main.py", line 1, in <module>

Hi @FrAmeS,

Thanks for posting!

Create a packages.txt file in your repo with the following line to install the apt-get dependency libgl:

libgl1

Alternatively, change in the requirements.txt file:
opencv-python-headless instead of opencv-python
