Missing requirements for streamlit

[mberg2007]

Creating a docker image and running streamlit with demo_web.py gives the following error immediately upon entering the web app from a browser:

$ docker run -p 8501:8501 sdopenvino:latest

  You can now view your Streamlit app in your browser.

  Network URL: http://172.17.0.2:8501
  External URL: http://80.208.65.21:8501

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 556, in _run_script
    exec(code, module.__dict__)
  File "/src/demo_web.py", line 6, in <module>
    from streamlit_drawable_canvas import st_canvas
ModuleNotFoundError: No module named 'streamlit_drawable_canvas'

I fixed this by running a pip install of the streamlit_drawable_canvas module. I guess this module should be part of requirements.txt?

I had the same error just running the demo_web.py through a virtual environment. The problem was fixed with your suggestion

pip install streamlit_drawable_canvas

I agree, it should be part of the requirements.txt
