Dear guix, Since I made the last update to this series, someone did work in the python science packages and I had to publish a new rebase of my work, discarding duplicate packaging efforts. I also used that opportunity to update my dependencies. Could you publish the new rebase in a new branch? Previously, nckx did it to wip-python-mne. It was of great help to me because I can use the branch in gitlab CI without having to patch and rebuild guix in the pipeline. It would be wiser to use a new branch, based on master. Thank you for the time you already spent helping me. Best regards, Vivien
