I noticed that interactive widgets are not working in my Jupyter Lab notebooks.
The following code should produce an interactive slider but doesn't:
from ipywidgets import interact, interactive, fixed, interact_manual
import ipywidgets as widgets
def f(x):
return x
interact(f, x=10);
What is the problem here, and how can I get widgets to work?

Jupyter Notebook has support for many kinds of interactive outputs, including the ipywidgets ecosystem as well as many interactive visualization libraries.
Simply install the python ipywidgets package with pip (pip install ipywidgets==7.6. 0) or conda/mamba (conda install -c conda-forge ipywidgets=7.6. 0) and ipywidgets will automatically work in classic Jupyter Notebook and in JupyterLab 3.0.
Jupyter doesn't load or doesn't work in the browserTry disabling any browser extensions and/or any Jupyter extensions you have installed. Some internet security software can interfere with Jupyter. If you have security software, try turning it off temporarily, and look in the settings for a more long-term solution.
You need to install widget extension
pip install ipywidgets
jupyter nbextension enable --py widgetsnbextension --sys-prefix
