New in version 0.8.0.
The web-based LiberTEM GUI can be integrated into existing JupyterLab and JupyterHub installations. That way, the existing authentication and user management infrastructure of Jupyter can be re-used to offer LiberTEM as a service. The LiberTEM GUI will have access to the same data that is available to Jupyter notebooks.
Currently, a fork of
jupyter-server-proxy needs to be used, which
includes a fix to allow restarting LiberTEM after a graceful shutdown, see
The fork also includes other unreleased but necessary changes from the
master branch of
Installation can be done with the following commands, after having followed
the installation instructions below:
(jupyter-venv) $ git clone firstname.lastname@example.org:sk1p/jupyter-server-proxy.git (jupyter-venv) $ cd jupyter-server-proxy && git checkout websocket-fix-plus-restart (jupyter-venv) $ pip install .
Note that this needs to be done in the environment where
libertem-jupyter-proxy was installed.
As a first step, you will need to install LiberTEM-jupyter-proxy into the Python environment where JupyterHub or JupyterLab is installed. Then, you will also need an installation of LiberTEM, which can live in either the same Python environment, or in its own.
In case of a separate Python environment for LiberTEM, you will need to tell
LiberTEM-jupyter-proxy how to start the
libertem-server. This is done
with a simple JSON configuration file. The configuration file needs to be saved in the
Python environment where LiberTEM-jupyter-proxy is installed. If the virtualenv
that contains the Jupyter installation is created at
/opt/jupyter/venv/, the configuration filename should be
/opt/jupyter/venv/etc/libertem_jupyter_proxy.json. The contents should
look like this:
This allows to separate the Jupyter installation from the LiberTEM installation.
The given path can also point to a wrapper script, for example for further environment
preparations, like loading modules on an HPC system. The wrapper script should forward
any arguments it reveices to the
When the installation is finished, you can find the LiberTEM GUI as an entry
