@sbillinge I used package update but now both my local pytest and here raises ModuleNotFoundError. I have done pip install -e ., but still does not work. The traceback is shown below.

Lots of issues here. Please start over and let's go more slowly. Please do the no-edit updates, pre-commit updatess and so on. It will fail tests, but we can start merging things more easily. To be on the safe side I will make a migration branch and lets use that as base and merge to main at the end.

[sbillinge]

migration branch is created. Please use that as base. First PRs ideally would have no manual edits, just pre-commit and adding files that have not been modified. If you make mods for some reason, please let me know to make it easier to merge.

Closed as we do from migration branch.
