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).
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 command below 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
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.
