Summary

A large portion of our GitHub Actions CI tests.yml workflow matrix is composed of version range restrictions for Python packages:

matplotlib/.github/workflows/tests.yml

Lines 48 to 108 in 7d5d027

I think that most of these can now safely be removed.

In practice, three variables are currently declared in the workflow file:

$ grep ' .*-ver: ' .github/workflows/tests.yml | sort | uniq
            pygobject-ver: '<3.52.0'
            pyqt6-ver: '!=6.6.0'
            pyside6-ver: '!=6.5.1'

Proposed fix

Remove the version pin variables and template evaluation for:

  • pyside2-ver
  • pyqt6-ver
  • pyside6-ver
