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;

IOError                                   Traceback (most recent call last)
