[ aws . sagemaker ]



Starts a transform job. A transform job uses a trained model to get inferences on a dataset and saves these results to an Amazon S3 location that you specify.

To perform batch transformations, you create a transform job and use the data that you have readily available.

In the request body, you provide the following:

  • TransformJobName - Identifies the transform job. The name must be unique within an AWS Region in an AWS account.
  • ModelName - Identifies the model to use. ModelName must be the name of an existing Amazon SageMaker model in the same AWS Region and AWS account. For information on creating a model, see CreateModel .
  • TransformInput - Describes the dataset to be transformed and the Amazon S3 location where it is stored.
  • TransformOutput - Identifies the Amazon S3 location where you want Amazon SageMaker to save the results from the transform job.
  • TransformResources - Identifies the ML compute instances for the transform job.

For more information about how batch transformation works Amazon SageMaker, see How It Works .

--transform-job-name (string)

The name of the transform job. The name must be unique within an AWS Region in an AWS account.

--model-name (string)

The name of the model that you want to use for the transform job. ModelName must be the name of an existing Amazon SageMaker model within an AWS Region in an AWS account.

--max-concurrent-transforms (integer)

The maximum number of parallel requests that can be sent to each instance in a transform job. This is good for algorithms that implement multiple workers on larger instances . The default value is 1 . To allow Amazon SageMaker to determine the appropriate number for MaxConcurrentTransforms , set the value to 0 .

--max-payload-in-mb (integer)

The maximum payload size allowed, in MB. A payload is the data portion of a record (without metadata). The value in MaxPayloadInMB must be greater or equal to the size of a single record. You can approximate the size of a record by dividing the size of your dataset by the number of records. Then multiply this value by the number of records you want in a mini-batch. We recommend to enter a slightly larger value than this to ensure the records fit within the maximum payload size. The default value is 6 MB.

For cases where the payload might be arbitrarily large and is transmitted using HTTP chunked encoding, set the value to 0 . This feature only works in supported algorithms. Currently, Amazon SageMaker built-in algorithms do not support this feature.

--batch-strategy (string)

Determines the number of records included in a single mini-batch. SingleRecord means only one record is used per mini-batch. MultiRecord means a mini-batch is set to contain as many records that can fit within the MaxPayloadInMB limit.

Batch transform will automatically split your input data into whatever payload size is specified if you set SplitType to Line and BatchStrategy to MultiRecord . There's no need to split the dataset into smaller files or to use larger payload sizes unless the records in your dataset are very large.

Possible values:

  • MultiRecord
  • SingleRecord

--environment (map)

The environment variables to set in the Docker container. We support up to 16 key and values entries in the map.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


TransformJobArn -> (string)

The Amazon Resource Name (ARN) of the transform job.
