Install plotly

[amabdallah]

Would you please install plotly on the jupyterhub?

I could install them as suggested by Tony through an email conversation in the first cell of the notebook but it seems that I have to do that each time I use the notebook which takes time.

ImportError: No module named plotly

!pip install plotly # python 2.7
!pip3 install plotly # python3
!conda install -c plotly plotly -y
