Public bug reported: Importing h5py (without MPI environment) results in a seg-fault.
Apparently h5py is linked to libhdf5_openmpi.so.103 which requires the program to be started via a mpirun. I wonder what is the rational behind this, so I suspect it is simply a bug. ``` kieffer@p9-01:~$ uname -a Linux p9-01 5.4.0-18-generic #22-Ubuntu SMP Sat Mar 7 18:06:34 UTC 2020 ppc64le ppc64le ppc64le GNU/Linux kieffer@p9-01:~$ lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 kieffer@p9-01:~$ dpkg -l |grep h5py ii python3-h5py 2.10.0-2build2 ppc64el general-purpose Python interface to hdf5 (Python 3) kieffer@p9-01:~$ python3 -c "import h5py" *** An error occurred in MPI_Init_thread *** on a NULL communicator *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, *** and potentially your MPI job) [p9-01:505264] 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! ``` ** Affects: h5py (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871115 Title: h5py seg-fault at import To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/h5py/+bug/1871115/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
