Missing ipywidgets Video after `pip install`

[kmader]

I tried doing a clean binder setup and pip installing ipywebrtc and get the following error message and see that there is no Video widget in ipywidgets. The setup is running ipywidgets 7.2.1 and the repo/notebook are here: https://github.com/kmader/ivissearch/blob/master/notebooks/SearchDemo.ipynb

You need ipywidgets 7.4, I guess the version requirements for pypi is not up to date.

thanks, works fine now!

FYI the command you need is pip install ipywidgets==7.4
