There are many places where we could make use of Pathlib.

Look for any places that uses with open(...) and ask yourself:

• is the argument a string ?
• would it make sens to make it a Path(),

Every kubeflow image should be scanned for security vulnerabilities.
It would be great to have a periodic security report.
Each of these images with vulnerability should be patched and updated.

could you add one of the spellchecker plugins?

The plotting UI leaves a lot to be desired:

Create a new notebook, add cells containing @__FILE__ and @__DIR__. Then move the file from the default location to a new name and location. For fun, add additional cells containing @__FILE__ and @__DIR__. Note that re-running the cells which display the out-of-date results does not cause them to update their results.
