[Paraview-developers] ParaView 5.5.0-RC3 problem importing h5py?

[Favre Jean]

Dear all

I have PV5.4 and pv5.5RC3 installed on my desktop and the Cray. Using python3 on both systems. Using the same modules for both versions.

With pv5.4, I can import h5py without any problem.

With 5.5RC3, the Cray compute node segfaults.

My Linux desktop also fails, with some more helpful messages:

./bin/pvpython
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import h5py

The use case is really to use h5py in Python Programmable Sources, but I see that pvpython fails too.

Anyone has tested importing h5py? I have the python3-h5py package installed from the standard rep. Outside of ParaView, python3 and h5py are working just fine.

Yes, I export HDF5_DISABLE_VERSION_CHECK=2 to get rid of warnings.
