python3 iteritems renamed to items in train_softmax.py

[amoderate]

                print('Saving statistics')
                with h5py.File(stat_file_name, 'w') as f:
                    for key, value in stat.iteritems():
                        f.create_dataset(key, data=value)

should be

 for key, value in stat.items():

Can confirm, I get AttributeError: 'dict' object has no attribute 'iteritems' without the change, but with the change, everything runs smoothly. Thanks for pointing this out!

I have the same question. Thanks very much.
