The issue arises as you’re trying to capture webcam input with OpenCV for an app deployed to Streamlit Cloud. I’ve explained why this isn’t possible and what you can do about it in these threads:
- Error while deploying app - #4 by snehankekre
- E: Unable to locate package cmake - #8 by snehankekre
- New Component: streamlit-webrtc, a new way to deal with real-time media streams
- streamlit-webrtc example
Best,
