I am having issues getting a demo in Python to work

I am receiving an error when trying to run the !commands in Jupyter notebook (for example '!./setup.sh'). These look like Linux commands, so not sure how to run through Jupyter notebook.

I would like to get the code working as described in article (http://cs230.stanford.edu/projects_fall_2020/reports/58656561.pdf) to generate answers to questions.

Links to Google Colab notebooks, can be found below:

In addition, some of the Colabs draw from a GitHub repository where the authors have made modifications to
the code base in some cases (e.g. Python 2 → Python 3): https://github.com/aaronzr/CS230
