-- Starts the running of the version of a model. Starting a model takes a
-- while to complete. To check the current state of the model, use
-- DescribeProjectVersions.
--
-- Once the model is running, you can detect custom labels in new images by
-- calling DetectCustomLabels.
--
-- You are charged for the amount of time that the model is running. To
-- stop a running model, call StopProjectVersion.
--
-- For more information, see /Running a trained Amazon Rekognition Custom
-- Labels model/ in the Amazon Rekognition Custom Labels Guide.
