[Users] .h5 file issue.

[Bilal Hameed]

Dear Users,

I am trying to open a .h5 file in jupyter-notebook. Please anyone guide 
me about reading of HDF files.

*_Command;_*


import h5py
filename = "ct_multilevel-err.h5"
with h5py.File(filename, "r") as f:
     # List all groups
     print("Keys: %s" % f.keys())
     a_group_key = list(f.keys())[0]

     # Get the data
     data = list(f[a_group_key])

*_Error;_*
