create-batch-prediction

Description

Generates predictions for a group of observations. The observations to process exist in one or more data files referenced by a DataSource . This operation creates a new BatchPrediction , and uses an MLModel and the data files referenced by the DataSource as information sources.

CreateBatchPrediction is an asynchronous operation. In response to CreateBatchPrediction , Amazon Machine Learning (Amazon ML) immediately returns and sets the BatchPrediction status to PENDING . After the BatchPrediction completes, Amazon ML sets the status to COMPLETED .

You can poll for status updates by using the GetBatchPrediction operation and checking the Status parameter of the result. After the COMPLETED status appears, the results are available in the location specified by the OutputUri parameter.

Synopsis

  create-batch-prediction
--batch-prediction-id <value>
[--batch-prediction-name <value>]
--ml-model-id <value>
--batch-prediction-data-source-id <value>
--output-uri <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--batch-prediction-id (string)

A user-supplied ID that uniquely identifies the BatchPrediction .

--batch-prediction-name (string)

A user-supplied name or description of the BatchPrediction . BatchPredictionName can only use the UTF-8 character set.

--ml-model-id (string)

The ID of the MLModel that will generate predictions for the group of observations.

--batch-prediction-data-source-id (string)

The ID of the DataSource that points to the group of observations to predict.

--output-uri (string)

The location of an Amazon Simple Storage Service (Amazon S3) bucket or directory to store the batch prediction results. The following substrings are not allowed in the s3 key portion of the outputURI field: ‘:’, ‘//’, ‘/./’, ‘/../’.

Amazon ML needs permissions to store and retrieve the logs on your behalf. For information about how to set permissions, see the Amazon Machine Learning Developer Guide .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Output

BatchPredictionId -> (string)

A user-supplied ID that uniquely identifies the BatchPrediction . This value is identical to the value of the BatchPredictionId in the request.
