As I am trying to run parallel hdf5 with h5py and mpi4py, I am met with the following error:

 NameError: global name 'mpi4py' is not defined

Googling suggests that this is because h5py is not "mpi-aware" and suggests recompiling. I would like to do this within the package system, such that I can update packages safely, etc. How can I achieve this?

  • You are using Python 2 I assume?

  • I tried with both 2 and 3. The difference is that python3 will not say "global" in front of name in the error message.
