Jupyter Notebooks

Jupyter Notebooks are documents which can contain live (Python) code, equations, visualizations and narrative text and can be used as an intuitive interface for OGS projects. The following video gives an introduction to using OpenGeoSys with Jupyter Notebooks:

Jupyter Notebooks container environments

You can use a pre-defined container environment.

Image registry.opengeosys.org/ogs/ogs/ogs-serial-jupyter contains:

  • The Jupyter Notebook / Lab application
  • The latest OpenGeoSys application with MFront-support and tools
  • A set of Python packages:
  • Jupyter-related tools:
    • nbconvert — Format conversion
    • nbdime — Diffs for notebooks
    • nb2hugo — Notebook to website markdown conversion
  • Gmsh — Mesh generator (incl. Python bindings)

Image registry.opengeosys.org/ogs/ogs/ogs-petsc-jupyter additionally contains:

  • PETSc-support


With Docker:

docker run --rm -p 8888:8888 -v $PWD:/home/jovyan/work --user `id -u $USER` \
    --group-add users registry.opengeosys.org/ogs/ogs/ogs-serial-jupyter

This mounts your current directory into ~/work inside the container. Use image registry.opengeosys.org/ogs/ogs/ogs-petsc-jupyter for PETSc-support!

Windows notes

The above command only works when you run Docker from within a WSL2 Linux shell!

  • Install Docker Desktop on Windows, it automatically configures WSL2.
  • Install a Linux distribution from the Microsoft App Store. We recommend Ubuntu 20.04.
  • In the Docker Desktop application under Settings / Resources / WSL integration add your Linux distribution.
  • Open a command prompt in your Linux distribution (At the start menu type the name of the distribution) and run the container.
    • If your current working contains spaces write out $PWD, e.g.:

      ... -v /c/Users/My\ Name/working/directory:/home/jovyan/work ...

With Singularity:

singularity run docker://registry.opengeosys.org/ogs/ogs/ogs-serial-jupyter

Open the specified URL shown in the command output in your browser, e.g.

You may have to modify the IP address if this is running on a remote machine.

Specific OGS version

You can append a version number to the image name (applies both to Docker and Singularity) to get an image for a specific OGS release (starting with 6.4.1):

singularity run docker://registry.opengeosys.org/ogs/ogs/ogs-serial-jupyter:6.4.1

Available images are listed on GitLab.

Browsing notebooks on GitLab

In the file browser on the left-hand side of the Jupyter Lab interface there is a GitLab-tab which allows for browsing and opening notebooks from the ogs/ogs-repository. You can directly modify and execute a notebook, but the notebook is not saved back to GitLab. You can change the browsed repository by typing into the top text field.

If you would like to us this with private repositories you have to supply an access token at container start-up:

docker run --rm -p 8888:8888 -v $PWD:/home/jovyan/work --user `id -u $USER` \
    --group-add users registry.opengeosys.org/ogs/ogs/ogs-serial-jupyter \
    --GitLabConfig.access_token="< YOUR_ACCESS_TOKEN >"

Adding additional Python packages

In a running container you can install additional Python packages with the Jupyter magic command %pip:

%pip install [package name]

Please note that this is a temporary installation. If you stop the container the environment is destroyed.

Rendering with PyVista

When using PyVista the container uses the (interactive) rendering backend ipyvtklink per default. Other backends are currently not supported.

The backend can be set via:

import pyvista as pv

pv.set_jupyter_backend('ipyvtklink') # default
pv.set_jupyter_backend('pythreejs')  # see https://docs.pyvista.org/user-guide/jupyter/pythreejs.html
pv.set_jupyter_backend('static')     # static images
