ModuleNotFoundError：没有名为“cv2”的模块

Question

I am getting this error when trying to deploy my streamlit app. It runs perfectly when I execute it through vscode. How to fix it?

File "/home/appuser/venv/lib/python3.9/site-packages/streamlit/scriptrunner/script_runner.py", line 475, in _run_script
    exec(code, module.__dict__)File "/app/face-emotion-recognition/streamlit_app.py", line 3, in <module>
    import cv2

Answer 1

Maybe that's because you've only installed the cv2 module in VSCode. Try installing it in the platform you're currently using.
