As you propably know, we will rename/remove some unused/outdated/ python modules, please see the details here. Since the jupyterhub kernels are based on modules, the deprecated kernels will no longer be available as default kernels in jupyter notebooks/labs.
NO PANIC, if you have been working with those deprecated kernels and want to continue using them in your notebooks, please follow the steps below.

The default location for R packages is not writeble and you can not install new packages. On demand we install new packages system-wide and for all users. However, it possible to install packages in different locations than root and here are the steps:
create a directory in

We have seen in this blog post how to encapsulate a jupyter notebook (server) in a singularity container . In this tutorial, I am going to describe how you can run a jupyter kernel in a container and make it available in the jupyter*.
Possible use case for this is to install a supported
and work with jupyter notebooks (see GLIBC and the container-based workaround).

We already provide a kernel for Julia based on the module julia/1.7.0.
In order to use it, you only need to install ÌJulia:

Kernels are based on python environments created with
virtualenv or other package manager. In some cases, the size of the
environment can tremendously grow depending on the installed packages.
The default location for python files is the
$HOME directory. In
this case, it will quickly fill your quota. In order to avoid this, we
suggest that you create/store python files in other directories of the
filesystem on Mistral.
The following are two alternative locations where you can create your Python environment:

This is a follow up on Kernels. In
some cases, the process of publishing new Python modules can take long.
In the meantime, you can create a
test kernel to use it in
Jupyterhub. Creating new conda environments and using them as kernels
has been already described here. In
this example, we are not going to create a new conda env but only the
kernel configuration files.
in this tutorial, I will take the module python3/2021-01. as an example.
