google cloud datastore - App Engine remote_api from one instance to another -

i have app engine app create model objects , put them app. on dev_server application work's great when upload code app engine i've got error:

from google.appengine.ext.remote_api import remote_api_stub

importerror: cannot import name remote_api_stub

in documentation written remote_api can used connect dev_server app instance , 1 instance didn't find explanation how can this.

where remote_api_stub on app engine? or in documentation bug?

you can use remote api access datastore of 1 app engine app different app engine app.
