<pre>The notebooks in &quot;notebooks/&quot; require the dependencies specified in &quot;requirements.txt&quot; to be installed. They rely on data files in &quot;data/&quot;. These data can be obtained by running the &quot;convert.py&quot; scripts in that folder. The script requires data files from &quot;data-raw/&quot;. These files can be generated by running &quot;extract.py&quot; in that folder. This script requires the libraries.io data dump, as explained in the README file contained in this folder.
