Plotly and notebook mode

[bene]

Hi there,

I am new in using the data science workbench. However I have some experience with notebooks and I tried to get visulatisations done with plotly. The result when I try to initialize the notebook mode or plot something is always the same error and no output:

I am quite sure somebody else had similar problems and maybe someone can point me to a solution.

Thanks and cheers
