I followed the instructions for setting up the talkmap, but when I look at talkmap_out.ipynb, there is an error halting the notebook at the first chunk.

This is the chunk:

# Start by installing the dependencies !pip install python-frontmatter getorg --upgrade import frontmatter import glob import getorg from geopy import Nominatim from geopy.exc import GeocoderTimedOut

And this is the output:
