TimePicker not found?

I am trying to create a TimePicker widget using a Jupyter Notebook but I am getting the following error:

The code I run is:

import ipywidgets as widgets
    description='Pick a Time',

The widget works fine in the interactive online version (Binder) of the ipywidgets Widget List.

But when I ran it in a Google Colab notebook I get the same error.

Any thoughts/suggestions would be more than welcome :wink:

The latest docs (and the binder) are currently tracking to the release one would get with pip install ipywidgets --pre (currently 8.0.0b0).

For the more widely distributed 7.6.x line, the stable docs are accurate.
