Source: petsc4py Followup-For: Bug #918044 It's the other way around. slepc4py depends on petsc4py, petsc4py does not depend on slepc4py.
As far as I can see the tests are working fine. slepc4py 3.9 requires petsc4py 3.9, and therefore fails when attempting to install with petsc4py 3.10. The versioned dependencies are already there. The true villain here is numpy, I think. Drew
