Is it possible to generate interactive plotly visualizations in the jupyter notebooks on the RAP? I can load the plotly package and can execute the code but I just see a blank where the visualizations should be.

  The following steps worked on my side:

   

  A) First go to the notebook and install plotly dependencies, including dependencies for JupyterLab:

   

  %%bash

  pip install plotly==5.14.1

  pip install "jupyterlab>=3" "ipywidgets>=7.6"

  pip install jupyter-dash

   

  2) Go to Terminal and execute the following commands to install additional JupyterLab extensions:

   

  jupyter labextension install plotlywidget

  jupyter labextension list

  jupyter lab build

   

  Note: I faced several error messages during this step, so maybe some of the commands are not necessarily.

   

  3) Go back to a notebook cell, and paste:

   

  import plotly.io as pio

  pio.renderers.default = "iframe"

   

  4) I tested the all steps above with the following:

   

  import plotly.express as px

  fig = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])

  fig.show()

   

  5) I would recommend then creating/saving a snapshot, so your JupyterLab env can be reused in your future session and you do not need to install plotly again.
