Plotly is not working in Jupyterlab. I assume that there is a conflict in required extensions but I'm not sure.
On checking troubleshooting on Plotly <https://plotly.com/python/troubleshooting/> , they advise to remove extensions and install them again.
But I found that there is additional extension that came with Jupyterlab update called '**jupyterlab-plotly-extension**'
which is not mentioned by Plotly in their instructions to make it working in JupyterLab <https://plotly.com/python/getting-started/#jupyterlab-support-python-35>

My question is: which extensions should be installed to make Plotly working in JupyterLab?

* jupyterlab-plotly as mentioned in Plotly support
* jupyterlab-plotly-extension that came with JupyterLab
