Support for ipywidgets 8

[tilusnet]

Hi,

When is ipywidgets 8.0+ compatibility planned for?

[edvard-bjarnason]

Hi,

The problem now is that when you install in a clean environment you get ipywidgets 8 and then no widgets are rendered by volia :( and no clear error messages about what the problem is...

pip install voila
pip install jupyter
voila
... and no widgets are rendered in notebooks

can be solved by:
pip install ipywidgets==7.7.2

thanks @afonit

It's probable that this PR will get in instead #846. It is turning Voila into a lab-based application and updating to ipywidgets 8.

I spent two days worth of time to debug and find the cause that voila stopped working in my side, and this is the reason!

Widgets did not appear because of Voila did not support ipywidgets>8.0!!!

Easy fix:

pip install ipywidgets<8.0

---

Lesson learned: better to pin all version in requirements.txt next time

If anyone has issues with ipywidgets<8.0 try

pip install jupyterlab-widgets==1.1.1

the latest version of jupyterlab-widgets is not compatible with ipywidgets<8.0
