Hi Drew I followed the discussion on the upstream issue. What do you think of adding some extra test dependencies to mpi4py's debian/tests/control?
Depends: python3-mpi4py, + libpmix-dev, + libucx-dev [amd64 arm64 ppc64el], python3-cffi, python3-dill, python3-distutils, This will make sure mpi4py's autopkgtests are run when pmix and ucx are updated as well. Regards Graham
