Parameters
----------

# Attach h2o_frame to dataframe which forces python not to delete the frame when we leave the scope of this
# method.
# Without this, after leaving this method python would garbage collect the frame since it's not used
# anywhere and spark. when executing any action on this dataframe, will fail since the frame
# would be missing.
