JupyterLab 4.2
Systems Available
JupyterLab 4.2 is available on these systems:
- JSC-Cloud
On JSC-Cloud only files in
/home/jovyan
are stored persistently. Everything else will be lost after a restart.
Pre-installed kernels
The kernels listed in this documentation may not always be up-to-date, as they can change periodically. For the current list of available kernels, please check the web service. The configuration files used to install these kernels are stored here in our GitHub repository.
You can select them by navigating to the Kernels and Extensions tab on the left side of your configuration.

Kernel customization
These tutorials were created for HPC systems. Kernel creation on cloud resources (like JSC-Cloud) might require different steps. We may offer some documentation specifically for cloud resources in the future.
- Create kernel with virtualenv
- Create kernel with conda
- Create kernel with pyenv
- Create a containerized kernel with singularity
- Modify or extend a running kernel
Extensions
The extensions listed in this documentation may not always be up-to-date, as they can change periodically. For the current list of available extensions, please check the web service. The configuration files used to install these extensions are stored here in our GitHub repository.
