[SciPy-User] opening a hdf5 file using h5py

[Bala subramanian]

Friends,
I am a newbie to using hdf5 files. I need to work on hdf5 format file. To do
this, i installed h5py and numpy (in fedora 14) and to make sure if it
works, I tried to open a hdf5 format file using the following code as given
in the example section of h5py home page.

#!/usr/bin/env python
import h5py
f=h5py.File('eg.hdf5','r')

I am getting the following error. Someone kindly write me what is the
problem here. I tried to google the error but i am not understanding what is
going wrong.

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    f=h5py.File('eg.hdf5','r')
