I am quoting here some comments from: https://phabricator.wikimedia.org/T400266#11034580 related to issues we faced during updating blubber for revertrisk model.

@gkyziridis o/ I think that the problem may be due to setting use-system-site-packages to false, since we explicitly copy from /opt/lib/python/site-packages in the production variant (from the build one).

Thank you for your fast response, much appreciated.
I used the use-system-site-packages: false because the current blubber had the: use-system-flag: false using the old schema.
I opened a new task for tackling that because we want to proceed with the bookworm updates in the rest of the models as well: https://phabricator.wikimedia.org/T400446

Yes yes it makes sense! In Bookworm the Python convention changed, namely the "system" path is by default reserved for Python Debian package, and pip-related installs should go in a venv. I am not 100% sure what is the guideline from Releng, but it may be ok to just create a venv in the blubber file and pip install packages on it (and eventually copy that from the build variant to the prod one).
