I used the following commands:
$ wget http://h5py.googlecode.com/files/h5py-2.2.0.tar.gz $ tar -xzf h5py-2.2.0.tar.gz $ cd h5py-2.2.0 $ export C_INCLUDE_PATH=/usr/lib/openmpi/include
If you don’t issue the last command, you will see errors like “mpi.h” cannot be found
$ python setup.py build $ python setup.py test $ sudo python setup.py install
By now, you have h5py installed. Try this example: https://github.com/h5py/h5py/blob/2.1/examples/multiprocessing_example.py, and observe a beautiful picture generated using all processors on your computer.
