CreateProjectVersion
Creates a new version of a model and begins training.
Models are managed as part of an Amazon Rekognition Custom Labels project. You can
specify
one training dataset and one testing dataset. The response from CreateProjectVersion
is an Amazon Resource Name (ARN) for the version of the model.
Training takes a while to complete. You can get the current status by calling DescribeProjectVersions.
Once training has successfully completed, call DescribeProjectVersions to get the training results and evaluate the model.
After evaluating the model, you start the model by calling StartProjectVersion.
This operation requires permissions to perform the rekognition:CreateProjectVersion
action.
