<p>Creates a new Amazon Rekognition Custom Labels dataset. You can create a dataset by using an Amazon Sagemaker format manifest file or by copying an existing Amazon Rekognition Custom Labels dataset.</p> <p>To create a training dataset for a project, specify <code>train</code> for the value of <code>DatasetType</code>. To create the test dataset for a project, specify <code>test</code> for the value of <code>DatasetType</code>. </p> <p>The response from <code>CreateDataset</code> is the Amazon Resource Name (ARN) for the dataset. Creating a dataset takes a while to complete. Use <a>DescribeDataset</a> to check the current status.
