Hi @vhphan,
Can you double check that you have the specified versions of JupyterLab and the JupyterLab extensions installed as well?
pip install jupyterlab==0.32.1
export NODE_OPTIONS=--max-old-space-size=4096
jupyter labextension install @jupyter-widgets/jupyterlab-manager@0.35 # install the Jupyter widgets extension
jupyter labextension install plotlywidget@0.2 # FigureWidget support
jupyter labextension install @jupyterlab/plotly-extension@0.16 # offline iplot support
If things still aren’t working, please post the result of running pip list and jupyter labextension list in your environment.
Thanks!
