Plotlywidget nbextension error

Oh sorry, I misunderstood your situation. No, if you’re using the classic notebook none of that JupyterLab info is necessary :slightly_smiling_face:

I’d recommend double checking that you have "notebook>=5.3" and "ipywidgets>=7.2" installed using either conda or pip (not both).

If that doesn’t help, could you include your full output of:

  • pip list
  • jupyter nbextension list
  • conda list
