Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

This is the Amazon Lookout for Vision API Reference. It provides descriptions of actions, data types, common parameters, and common errors.

Amazon Lookout for Vision enables you to find visual defects in industrial products, accurately and at scale. It uses computer vision to identify missing components in an industrial product, damage to vehicles or structures, irregularities in production lines, and even minuscule defects in silicon wafers — or any other physical item where quality is important such as a missing capacitor on printed circuit boards.

Sending a Request Using LookoutVision

var lookoutvision = new AWS.LookoutVision();
lookoutvision.createDataset(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the LookoutVision object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var lookoutvision = new AWS.LookoutVision({apiVersion: '2020-11-20'});

You can also set the API version globally in AWS.config.apiVersions using the lookoutvision service identifier:

AWS.config.apiVersions = {
  lookoutvision: '2020-11-20',
  // other service API versions
};

var lookoutvision = new AWS.LookoutVision();

Method Details

createDataset(params = {}, callback) ⇒ AWS.Request

Creates a new dataset in an Amazon Lookout for Vision project. CreateDataset can create a training or a test dataset from a valid dataset source (DatasetSource).

If you want a single dataset project, specify train for the value of DatasetType.

To have a project with separate training and test datasets, call CreateDataset twice. On the first call, specify train for the value of DatasetType. On the second call, specify test for the value of DatasetType.

This operation requires permissions to perform the lookoutvision:CreateDataset operation.

Service Reference:

• CreateDataset

Examples:

Calling the createDataset operation

var params = {
  DatasetType: 'STRING_VALUE', /* required */
  ProjectName: 'STRING_VALUE', /* required */
  ClientToken: 'STRING_VALUE',
  DatasetSource: {
    GroundTruthManifest: {
      S3Object: {
        Bucket: 'STRING_VALUE', /* required */
        Key: 'STRING_VALUE', /* required */
        VersionId: 'STRING_VALUE'
      }
    }
  }
};
lookoutvision.createDataset(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • ProjectName — (String)

    The name of the project in which you want to create a dataset.

  • DatasetType — (String)

    The type of the dataset. Specify train for a training dataset. Specify test for a test dataset.

  • DatasetSource — (map)

    The location of the manifest file that Amazon Lookout for Vision uses to create the dataset.

    If you don't specify DatasetSource, an empty dataset is created and the operation synchronously returns. Later, you can add JSON Lines by calling UpdateDatasetEntries.

    If you specify a value for DataSource, the manifest at the S3 location is validated and used to create the dataset. The call to CreateDataset is asynchronous and might take a while to complete. To find out the current status, Check the value of Status returned in a call to DescribeDataset.

    • GroundTruthManifest — (map)

      Location information for the manifest file.

      • S3Object — (map)

        The S3 bucket location for the manifest file.

        • Bucket — required — (String)

          The Amazon S3 bucket that contains the manifest.

        • Key — required — (String)

          The name and location of the manifest file withiin the bucket.

        • VersionId — (String)

          The version ID of the bucket.

    ClientToken is an idempotency token that ensures a call to CreateDataset completes only once. You choose the value to pass. For example, An issue, such as an network outage, might prevent you from getting a response from CreateDataset. In this case, safely retry your call to CreateDataset by using the same ClientToken parameter value. An error occurs if the other input parameters are not the same as in the first request. Using a different value for ClientToken is considered a new call to CreateDataset. An idempotency token is active for 8 hours.

    If a token is not provided, the SDK will use a version 4 UUID.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

        • "DELETE_FAILED"
      • StatusMessage — (String)

        The status message for the dataset.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

createModel(params = {}, callback) ⇒ AWS.Request

Creates a new version of a model within an an Amazon Lookout for Vision project. CreateModel is an asynchronous operation in which Amazon Lookout for Vision trains, tests, and evaluates a new version of a model.

To get the current status, check the Status field returned in the response from DescribeModel.

If the project has a single dataset, Amazon Lookout for Vision internally splits the dataset to create a training and a test dataset. If the project has a training and a test dataset, Lookout for Vision uses the respective datasets to train and test the model.

After training completes, the evaluation metrics are stored at the location specified in OutputConfig.

This operation requires permissions to perform the lookoutvision:CreateModel operation. If you want to tag your model, you also require permission to the lookoutvision:TagResource operation.

Using a different value for ClientToken is considered a new call to DeleteModel. An idempotency token is active for 8 hours.

    If a token is not provided, the SDK will use a version 4 UUID.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

});

Parameters:

• params (Object) (defaults to: {}) —
  • ResourceArn — (String)

    The Amazon Resource Name (ARN) of the model for which you want to list tags.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • Tags — (Array<map>)

      A map of tag keys and values attached to the specified model.

      • Key — required — (String)

        The key of the tag that is attached to the specified model.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

startModel(params = {}, callback) ⇒ AWS.Request

Starts the running of the version of an Amazon Lookout for Vision model. Starting a model takes a while to complete. To check the current state of the model, use DescribeModel.

A model is ready to use when its status is HOSTED.

Once the model is running, you can detect custom labels in new images by calling DetectAnomalies.

Note: You are charged for the amount of time that the model is running. To stop a running model, call StopModel.

This operation requires permissions to perform the lookoutvision:StartModel operation.

Service Reference:

• StartModel

Examples:

Calling the startModel operation

var params = {
  MinInferenceUnits: 'NUMBER_VALUE', /* required */
  ModelVersion: 'STRING_VALUE', /* required */
  ProjectName: 'STRING_VALUE', /* required */
  ClientToken: 'STRING_VALUE'
};
lookoutvision.startModel(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • ProjectName — (String)

    The name of the project that contains the model that you want to start.

  • ModelVersion — (String)

    The version of the model that you want to start.

  • MinInferenceUnits — (Integer)

    The minimum number of inference units to use. A single inference unit represents 1 hour of processing and can support up to 5 Transaction Pers Second (TPS). Use a higher number to increase the TPS throughput of your model. You are charged for the number of inference units that you use.

  • ClientToken — (String)

    ClientToken is an idempotency token that ensures a call to StartModel completes only once. You choose the value to pass. For example, An issue, such as an network outage, might prevent you from getting a response from StartModel. In this case, safely retry your call to StartModel by using the same ClientToken parameter value. An error occurs if the other input parameters are not the same as in the first request. Using a different value for ClientToken is considered a new call to StartModel. An idempotency token is active for 8 hours.

    If a token is not provided, the SDK will use a version 4 UUID.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • Status — (String)

      The current running status of the model.

      Possible values include:
      • "STARTING_HOSTING"
      • "HOSTED"
      • "HOSTING_FAILED"
