Comment 10 for bug 1616357

Translation setup for neutron-lib is configured appropriately [1].
Zanata (OpenStack translation platform) has neutron-lib resource as expected [2] but there is no language translates messages over 75%.
Translation import job in OpenStack infra imports translations only for languages with 75% translation [3].
As a result, no translation files exist for neutron-lib.

This is an expected result.
