Package: python3-h5py
Version: 2.10.0-2
Severity: serious
The latest version of h5py compiled against MPI completely fails to
import if there is no network connection:
servo:~ 0$ python3 -c 'import h5py; print("foo")'
--------------------------------------------------------------------------
No network interfaces were found for out-of-band communications. We require
at least one available network for out-of-band messaging.

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
orte_ess_init failed
--> Returned value Unable to start a daemon on the local node (-127)
instead of ORTE_SUCCESS

*** An error occurred in MPI_Init_thread

*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)
[servo:32114] Local abort before MPI_INIT completed completed successfully, but
am not able to aggregate error messages, and not able to guarantee that all
other processes were killed!
servo:~ 1$
Note the return code and that the print command was not executed. The
import actually caused python to crash without throwing an exception.
This is obviously unacceptable and very major usability issue.
As mention in other similar reports, please drop the MPI support in
the default build!
