Users can install the current version of ipywidgets with pip or conda.

With pip

pip install ipywidgets
jupyter nbextension enable --py widgetsnbextension

When using virtualenv and working in an activated virtual environment, the --sys-prefix option may be required to enable the extension and keep the environment isolated (i.e. jupyter nbextension enable --py widgetsnbextension --sys-prefix).

With conda

conda install -c conda-forge ipywidgets

Installing ipywidgets with conda will also enable the extension for you.

Installing the JupyterLab Extension

To install the JupyterLab extension you also need to run the below command in a terminal which requires that you have nodejs installed.

jupyter labextension install @jupyter-widgets/jupyterlab-manager

Note: A clean reinstall of the JupyterLab extension can be done by first running the jupyter lab clean command which will remove the staging and static directories from the lab directory. The location of the lab directory can be queried by executing the command jupyter lab path in your terminal.
