Using these commands from Contributing
(plotly_dev) $ pip install -r packages/python/plotly/requirements.txt
(plotly_dev) $ pip install -r packages/python/plotly/optional-requirements.txtwon't install modules e.g. wget, datashader, etc. that are used in docs.
I suggest we add optional-doc-requirements.txt to help install some of these modules so that we could more efficiently test the examples using:
jupyter-notebook doc/python
