  You can obtain it from Guix by running ‘guix pull’ followed by:

    guix environment --ad-hoc jupyter guix-jupyter -- jupyter notebook

  Alternatively, you can get the source from Git:

    git clone https://gitlab.inria.fr/guix-hpc/guix-kernel guix-jupyter
    cd guix-jupyter
    git checkout v0.2.1  # or a887e449cbf248113b25eac05507bd949c826554
    git tag -v v0.2.1

  The ‘git tag -v’ command checks the authenticity of your checkout.

• About

  Guix-Jupyter is a Jupyter “kernel” that interprets software deployment
  annotations, thereby making sure computations run in the right
  software environment.  Cells execute in isolated containers, which
  furthers reduces the risks of non-reproducibility.  Input data can be
  fetched by using an extra annotation, which must include the expected
  hash of the data.

• Excerpt from the ‘NEWS’ file

  * Changes in 0.2.1 (since 0.2.0)

  ** Bug fix

     Previously Guix-Jupyter would store container data in
     /tmp/guix-kernel, which prevented multiple users from running it on
     the same machine.  It now uses mkdtemp(3) to create that directory.

  * Changes in 0.2.0 (since 0.1.0)

  ** New functionality

  *** New ‘;;guix describe’ magic command

      Like the ‘guix describe’ shell command, it returns the currently-used
      channels.

  *** New ‘;;guix search’ magic command

      Return the list of packages matching the given patterns.

  *** ‘;;guix pin’ and ‘;;guix describe’ output includes links to VCS history

      This allows you to see the version-control system (VCS) history
      leading to the channel commit you’re using.

  *** Report build and download progress in the notebook

      When Guix starts downloading or building things, for instance in
      response to an environment creation via ‘;;guix environment’, a
      transient line in the notebook displays what’s being built or
      downloaded.

  *** Guile kernel can display SVG pictures

      The built-in Guile kernel now returns SVG for images produced by
      ‘guile-picture-language’ (see
      https://git.elephly.net/software/guile-picture-language.git).

  ** Bug fixes

  *** Gracefully handle package-not-found errors in ‘;;guix environment’

  *** Properly complete ‘;;guix’ magic commands

  *** Fix potential hang in ‘;;guix pin’

  *** Gracefully handle ‘;;guix download’ syntax errors
