// Creates a new version of a model within an an Amazon Lookout for Vision
// project. CreateModel is an asynchronous operation in which Amazon Lookout for
// Vision trains, tests, and evaluates a new version of a model. To get the current
// status, check the Status field returned in the response from DescribeModel . If
// the project has a single dataset, Amazon Lookout for Vision internally splits
// the dataset to create a training and a test dataset. If the project has a
// training and a test dataset, Lookout for Vision uses the respective datasets to
// train and test the model. After training completes, the evaluation metrics are
// stored at the location specified in OutputConfig . This operation requires
// permissions to perform the lookoutvision:CreateModel operation. If you want to
// tag your model, you also require permission to the lookoutvision:TagResource
// operation.
