   !pip install witwidget-gpu
   !jupyter labextension install wit-widget
   !jupyter labextension install @jupyter-widgets/jupyterlab-manager

What data did you pass into the witwidget? Can you provide a notebook that can reproduce the issue? Thanks.

@jameswex how can i give you the sample ipynb file?

[fenglin-ssb]
