Package: python3-mpi4py
Version: 3.0.2-13
Severity: normal
A simple import of the MPI subpackage causes a warning message to be
sent to stderr:
servo:~ 0$ python3 -c 'from mpi4py import MPI'
--------------------------------------------------------------------------
[[11193,1],0]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:
Module: OpenFabrics (openib)
Host: servo
Another transport will be used instead, although this may result in
lower performance.
NOTE: You can disable this warning by setting the MCA parameter
btl_base_warn_component_unused to 0.
--------------------------------------------------------------------------
servo:~ 0$
This is bad form and is causing problems to applications build against
packages using this library (such as h5py).
I'm guessing this is a problem with the underlying libhdf5? but I'm
not sure, and now sure how to track down where the issue is really
coming from.
Thanks.
jamie.
