Hi,

we are elaborating if apache zeppelin is a suitable tool for us for 
collaborative notebooks. So far, I am very happy. However, we often use plotly 
in our jupyter notebooks and I do not get plotly plots displayed in apache 
zeppelin.

I installed apache zeppelin 0.9.0. (binary package with all interpreters) on a 
Linux server and the python interpreter settings point to the python binary in 
a conda environment. This environment  contains pyspark and plotly 4.14.3.

My example code is:

%python

import plotly.io as pio
pio.renderers.default = 'notebook'


# x and y given as array_like objects
import plotly.express as px
fig = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
fig.show()


The result is an empty white output in zeppelin. Is plotly working in zeppelin 
and if so, what am I doing wrong? (sorry, if this question is a stupid one)

Any help is highly appreciated and If you need further information, please let 
me know.

Best regards,
Uwe
