2. JupyterLab

After starting a JupyterHub session you are presented with Jupyter’s which is the default tab in Jupyter’s user interface. This view shows you (amongst other things):

  • Files on the machine running your Jupyter session (here, the cluster), not your local machine. This behaves much like a desktop file browser application. Use this to find existing Notebooks (or text files) to open/run/edit.

  • A ‘Launcher’ tab that lets you

    • Create a new Jupyter Notebook using a ‘kernel’ in a specific Conda environment

    • Create a new Jupyter Console using a ‘kernel’ in a specific Conda environment

    • Start a new web-based terminal session

    • Create a new text file, Markdown file or Python code file

  • Tabs for open Notebooks, web-based terminal sessions and web-based file editing views.

JupyterLab interface

Warning

Certain directories may not be accessible via this interface:

  • /home/username

  • /data/username

  • /shared/volname

This set of directories are automounted i.e. made available to the user on demand but you cannot express that demand via this interface. If you browse into /data and it is empty or does not contain your personal subdirectory then you need to briefly open a Jupyter terminal and run:

ls /data/username

then that directory should subsequently be visible/accessible in the JupyterLab file browser.
