JOSS Review: Errros in Working_with_ipyparallel

[ayush9pandey]

I had to add !pip install ipyparallel to run this notebook, and then ran into this:

---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)

good call, I add description to the notebook, that after installing the ipyparallels package the cluster first has to be started.

as otherwise the error message you had showing would come up.

This has been fixed and the documentation is on readthedocs with the example.
