Does not work on MacOS

Jupyter notebook version: latest, just brew installed it.

Installation in Jupyter notebook

# Install matplotlib for data visualization
%matplotlib 
!pip install matplotlib

!pip install ipywidgets

Usage:

interact(plot_distribution, year=widgets.IntSlider(min=1, max=10, step=1, value=2))

It shows this as an output instead of a functioning slider:

interactive(children=(IntSlider(value=2, description='year', max=10, min=1), Output()), _dom_classes=('w…
<function __main__.plot_distribution(year)>

Same for me. I tried this:

cd "$(mktemp -t scratch --directory)"
uv init --name=test --python=3.12
uv add --dev jupyterlab ipywidgets

then wrote

from ipywidgets import IntSlider

slider = IntSlider()

print(slider.value ** 2)
