use versions 0.69.2+ of Streamlit to ensure full Streamlit Cloud functionality.
You should only use one requirements file for your app. If you include more than one (e.g.
requirements.txt and Pipfile). Streamlit will first look in the directory of your Streamlit app;
however, if no requirements file is found, Streamlit will then look at the root of the repo.
apt-get dependencies
If packages.txt exists in the repository we automatically detect it, parse it, and install the listed packages as described below. You can read more about apt-get in their docs.
Add apt-get dependencies to packages.txt, one package name per line. For example:
shell
    freeglut3-dev
    libgtk2.0-dev
