# This example reads integer data from dset.h5 file into Python floatng buffers.

import h5py
import numpy as np
#
# Open an existing file using default properties.
#
file = h5py.File('dset.h5','r+')
#
# Open "dset" dataset under the root group.
#
dataset = file['/dset']
#
# Initialize buffers,read and print data.
#
# Python float type is 64-bit, one needs to use NATIVE_DOUBLE HDF5 type to read data.
