super_resolution.py also imports data.py. Could we add an import path for it?

[Roshrini]

@wkcn super_resolution.py is already using data.py from its parent directory. Code used:
"this_dir = path.abspath(path.dirname(file))
sys.path.append(path.join(this_dir, path.pardir))"

Tested by running super_resolution.py and image_classification.py successfully with this change.
