Creates a new version of Amazon Rekognition project (like a Custom Labels model or
a custom adapter) and begins training. Models and adapters are managed as part of
a Rekognition project. The response from CreateProjectVersion is an Amazon
Resource Name (ARN) for the project version.
The FeatureConfig operation argument allows you to configure specific model or adapter
settings. You can provide a description to the project version by using the VersionDescription
argment. Training can take a while to complete. You can get the current status by
calling DescribeProjectVersions. Training completed successfully if the value
of the Status field is TRAINING_COMPLETED. Once training has successfully
completed, call DescribeProjectVersions to get the training results and evaluate
the model.
This operation requires permissions to perform the rekognition:CreateProjectVersion
action.
The following applies only to projects with Amazon Rekognition Custom Labels as the chosen feature:
You can train a model in a project that doesn't have associated datasets by specifying
manifest files in the TrainingData and TestingData fields.
If you open the console after training a model with manifest files, Amazon Rekognition Custom Labels creates the datasets for you using the most recent manifest files. You can no longer train a model version for the project by specifying manifest files.
Instead of training with a project without associated datasets, we recommend that you use the manifest files to create training and test datasets for the project.
For .NET Core this operation is only available in asynchronous form. Please refer to CreateProjectVersionAsync.

| InvalidParameterException | Input parameter violated a constraint. Validate your parameter before calling the API operation again. |
| LimitExceededException | An Amazon Rekognition service limit was exceeded. For example, if you start too many jobs concurrently, subsequent calls to start operations (ex: StartLabelDetection) will raise a LimitExceededException exception (HTTP status code: 400) until the number of concurrently running jobs is below the Amazon Rekognition service limit. |

| ResourceInUseException | The specified resource is already being used. |
| ResourceNotFoundException | The resource specified in the request cannot be found. |
| ServiceQuotaExceededException | The size of the collection exceeds the allowed limit. For more information, see Guidelines and quotas in Amazon Rekognition in the Amazon Rekognition Developer Guide. |
| ThrottlingException | Amazon Rekognition is temporarily unable to process the request. Try your call again. |
