There is a lot of info on using NDB API with Google App Engine Datastore but I can't find any info on how to use NDB with Google Cloud Datastore. The only module I found is googledatastore which is very primitive library.
How is App Engine Datastore different from the Cloud Datastore? Is NDB available for the Cloud Datastore?

NDB support outside of App Engine (using Google Cloud Datastore) is currently in development.
UPDATE: Check out the NDB development discussion on GitHub.
You might want to try using gcloud.datastore (pip install gcloud).
