Plotly python package is broken in current conda version in Azure ML

[efraintorlo]

Hi guys,

Firstly, I have to say that your Azure ML platform is just awesome and your decision to include Jupyter support is quite useful, thanks a lot for that!

Next, I wish to highlight a small issue that, in my humble opinion, is related with the Anaconda version that runs in the docker instances. It happens that when plotly package is imported in a Jupyter notebook the next error is obtained:

import plotly
