Jupyter notebook wont display widget

[robambalu]

I'm trying to get perspective working in a jupyter notebook. Ive followed the directions, installed perspective-python as well as jupyterlab extensions ( including ipywidget ).
Everything installed fine, but I'm trying the simplest example in my notebook and it wont display anything. I notice that when I just eval the widget, it doesn't just print the repr of it, so it seems like its trying to do something. Any debugging tips would be appreciated:

This looks like you're running Jupyter Notebook, which we do not support. Use JupyterLab instead.
