Rekognition / Client / update_dataset_entries




This operation applies only to Amazon Rekognition Custom Labels.

Adds or updates one or more entries (images) in a dataset. An entry is a JSON Line which contains the information for a single image, including the image location, assigned labels, and object location bounding boxes. For more information, see Image-Level labels in manifest files and Object localization in manifest files in the Amazon Rekognition Custom Labels Developer Guide.

If the source-ref field in the JSON line references an existing image, the existing image in the dataset is updated. If source-ref field doesn’t reference an existing image, the image is added as a new image to the dataset.

You specify the changes that you want to make in the Changes input parameter. There isn’t a limit to the number JSON Lines that you can change, but the size of Changes must be less than 5MB.

UpdateDatasetEntries returns immediatly, but the dataset update might take a while to complete. Use DescribeDataset to check the current status. The dataset updated successfully if the value of Status is UPDATE_COMPLETE.

To check if any non-terminal errors occured, call ListDatasetEntries and check for the presence of errors lists in the JSON Lines.

Dataset update fails if a terminal error occurs ( Status = UPDATE_FAILED). Currently, you can’t access the terminal error information from the Amazon Rekognition Custom Labels SDK.

This operation requires permissions to perform the rekognition:UpdateDatasetEntries action.

Request Syntax

response = client.update_dataset_entries(
        'GroundTruth': b'bytes'
  • DatasetArn (string) –


    The Amazon Resource Name (ARN) of the dataset that you want to update.

  • Changes (dict) –


    The changes that you want to make to the dataset.

    • GroundTruth (bytes) – [REQUIRED]

      A Base64-encoded binary data object containing one or JSON lines that either update the dataset or are additions to the dataset. You change a dataset by calling UpdateDatasetEntries. If you are using an AWS SDK to call UpdateDatasetEntries, you don’t need to encode Changes as the SDK encodes the data for you.

      For example JSON lines, see Image-Level labels in manifest files and and Object localization in manifest files in the Amazon Rekognition Custom Labels Developer Guide.
