generate hdf5 file?

[sunjunlishi]

labels = np.concatenate((label, regression_box, landmark), axis = 1)
with h5py.File(train_file_path, 'w') as f:
f['data'] = a
f['labels'] = labels
f['regression'] = regression_box
f['landmark'] = landmark

there are no need to use f['regression'] = regression_box f['landmark'] = landmark
because labels = np.concatenate((label, regression_box, landmark), axis = 1) has regression and landmark

does right?
