JupyterLab

Use the jupyterlab pack to install the JupyterLab interface into the system environment:

packs:
  jupyterlab: {}

Use the server.default_path setting (Server settings) set to /lab to make the JupyterLab interface the default UI to load.

It is possible to restrict the installed JupyterLab to a major revision:

packs:
  jupyterlab:
    version: 4

Currently only version 4 is supported.
