Add nbformat to dependencies

See original GitHub issue

Apparently nbformat is required by the latest plotly version. After a clean install if I try to plot I receive back this error

ValueError: Mime type rendering requires nbformat>=4.2.0 but it is not installed

If you want I can update the requirements that I guess are here.

Same issue arises when using Jupyter notebooks within VSCode, which seems to be becoming a popular Jupyter client.

Hi @rpanai thank you for the report. On top of the requirements listed in requirements.txt, we also have some optional requirements which are not installed by defaults. nbformat is indeed needed to display figures in the notebook. It is a hard dependency of the jupyter-notebook package, so you must have it installed unless you have a very old version of the notebook (nbformat 4.2 was released in December 2016). Could you please confirm that you trying to plot plotly figures inside the jupyter notebook, and also check the versions of jupyter notebook and nbformat which you are using? I don’t think we will update the requirements.txt because it’s only an optional dependency and for a large majority of users (who have updated the notebook since Dec. 2016) it will be already installed. Of course if this is more complex happy to keep on discussing this with you.
