It looks like the change to setup.py #83 makes the assumption that jupyter/notebook libraries are available apriori.

This has broken CI tests for a project ( https://github.com/vertexproject/synapse/ ) that uses hide-code as part of its documentation test/generation workflows.

We rolled a temporary constraint into this PR to unblock our project (linked back to issues in this repo seems to fail) here https://github.com/vertexproject/synapse/pull/1527

Resolved in v0.6.0. Install with pip install hide_code[all].
