Using Julia in Jupyterhub

System-based Julia

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:

  1. module load julia && julia

  2. ]

  3. add “IJulia”

  [xxxx@levante4 ~]$ module load julia && julia

User-based Julia

If you are using your own Julia installation following (correctly) the instructions described here:

wget https://julialang-s3.julialang.org/bin/linux/x64/1.6/julia-1.6.0-linux-x86_64.tar.gz
tar zxvf julia-1.6.0-linux-x86_64.tar.gz

you can use it in Jupyterhub.

How?

all what you need is to install the ÌJulia package (official link):

using Pkg
Pkg.add("IJulia")

Note

Start Julia from the unzipped: julia-1.6.0/bin/julia.

after this, you will see a new kernel in jupyterhub julia-1.6.0.

Install packages

  • it is preferable to activate an environment first: Pkg.activate("path/to/env")

  • default env is .julia in your $HOME directory

  • Pkg.add("new-package")

Warning

The installed packages version depends sometimes on a specific Julia release. Possible issues are not necessarly related to Mistral or Jupyterhub. Please, check their troubleshootings section first!
