update_dataset_entries

update_dataset_entries(**kwargs)

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(
    DatasetArn='string',
    Changes={
        'GroundTruth': b'bytes'
    }
)

Parameters

• DatasetArn (string) --

  [REQUIRED]

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

• Changes (dict) --

  [REQUIRED]

  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 .
