Hi Paula,

I merged the MR. It did not build anything though as you have not specified a particular version for the packages in the spack.yaml. If you want a particular version to be available in the default "EBRAINS" JupyterLab kernel (i suppose you want the latest?) you need to specify it in the spack.yaml for your tools.

Check out the newly created documentation for the Spack pipelines. I think that the section for the Developers would be mostly interesting to you.

Best, Thanassis
