Dear Jamie,

I believe:
  - the issue is not very serious, as it will not prevent your code from
running fine and efficiently (it's only an informative message).

  - it is not in python3-h5py but somewhere in the MPI stack (I have no
time right now for investigating, but I have seen this recently in
another MPI code: gyoto).

  - downgrading only solves your issue because version 2.8.0 was not
linked with MPI (and therefore may be less efficient, depending on
hardware).

Kind regards, Thibaut.
