#algorithm_specificationTypes::AlgorithmSpecification

Information about the algorithm used for training, and algorithm metadata.

Returns:

#billable_time_in_secondsInteger

The billable time in seconds.

You can calculate the savings from using managed spot training using the formula (1 - BillableTimeInSeconds / TrainingTimeInSeconds) * 100. For example, if BillableTimeInSeconds is 100 and TrainingTimeInSeconds is 500, the savings is 80%.

Returns:

  • (Integer)

    The billable time in seconds.

#checkpoint_configTypes::CheckpointConfig

Contains information about the output location for managed spot training checkpoint data.

Returns:

  • (Types::CheckpointConfig)

    Contains information about the output location for managed spot training checkpoint data.

#creation_timeTime

A timestamp that indicates when the training job was created.

Returns:

  • (Time)

    A timestamp that indicates when the training job was created.

#enable_inter_container_traffic_encryptionBoolean

To encrypt all communications between ML compute instances in distributed training, choose True. Encryption provides greater security for distributed training, but training might take longer. How long it takes depends on the amount of communication between compute instances, especially if you use a deep learning algorithms in distributed training.

Returns:

  • (Boolean)

    To encrypt all communications between ML compute instances in distributed training, choose True.

#enable_managed_spot_trainingBoolean

A Boolean indicating whether managed spot training is enabled (True) or not (False).

Returns:

  • (Boolean)

    A Boolean indicating whether managed spot training is enabled (True) or not (False).

#enable_network_isolationBoolean

If you want to allow inbound or outbound network calls, except for calls between peers within a training cluster for distributed training, choose True. If you enable network isolation for training jobs that are configured to use a VPC, Amazon SageMaker downloads and uploads customer data and model artifacts through the specified VPC, but the training container does not have network access.

The Semantic Segmentation built-in algorithm does not support network isolation.

Returns:

  • (Boolean)

    If you want to allow inbound or outbound network calls, except for calls between peers within a training cluster for distributed training, choose True.

#hyper_parametersHash<String,String>

Algorithm-specific parameters.

Returns:

  • (Hash<String,String>)

    Algorithm-specific parameters.

#input_data_configArray<Types::Channel>

An array of Channel objects that describes each data input channel.

Returns:

  • (Array<Types::Channel>)

    An array of Channel objects that describes each data input channel.

#labeling_job_arnString

The Amazon Resource Name (ARN) of the Amazon SageMaker Ground Truth labeling job that created the transform or training job.

Returns:

  • (String)

    The Amazon Resource Name (ARN) of the Amazon SageMaker Ground Truth labeling job that created the transform or training job.

#last_modified_timeTime

A timestamp that indicates when the status of the training job was last modified.

Returns:

  • (Time)

    A timestamp that indicates when the status of the training job was last modified.

#model_artifactsTypes::ModelArtifacts

Information about the Amazon S3 location that is configured for storing model artifacts.

Returns:

  • (Types::ModelArtifacts)

    Information about the Amazon S3 location that is configured for storing model artifacts.

#output_data_configTypes::OutputDataConfig

The S3 path where model artifacts that you configured when creating the job are stored. Amazon SageMaker creates subfolders for model artifacts.

Returns:

  • (Types::OutputDataConfig)

    The S3 path where model artifacts that you configured when creating the job are stored.

#resource_configTypes::ResourceConfig

Resources, including ML compute instances and ML storage volumes, that are configured for model training.

Returns:

  • (Types::ResourceConfig)

    Resources, including ML compute instances and ML storage volumes, that are configured for model training.

#role_arnString

The AWS Identity and Access Management (IAM) role configured for the training job.

Returns:

  • (String)

    The AWS Identity and Access Management (IAM) role configured for the training job.

#secondary_statusString

Provides detailed information about the state of the training job. For detailed information on the secondary status of the training job, see StatusMessage under SecondaryStatusTransition.

Amazon SageMaker provides primary statuses and secondary statuses that apply to each of them:

InProgress
  • Starting - Starting the training job.

  • Downloading - An optional stage for algorithms that support File training input mode. It indicates that data is being downloaded to the ML storage volumes.

  • Training - Training is in progress.

  • Interrupted - The job stopped because the managed spot training instances were interrupted.

  • Uploading - Training is complete and the model artifacts are being uploaded to the S3 location.

Completed
  • Completed - The training job has completed.

^

Failed
  • Failed - The training job has failed. The reason for the failure is returned in the FailureReason field of DescribeTrainingJobResponse.

^

Stopped
  • MaxRuntimeExceeded - The job stopped because it exceeded the maximum allowed runtime.

  • MaxWaitTmeExceeded - The job stopped because it exceeded the maximum allowed wait time.

  • Stopped - The training job has stopped.

Stopping
  • Stopping - Stopping the training job.

^

Valid values for SecondaryStatus are subject to change.

We no longer support the following secondary statuses:

  • LaunchingMLInstances

  • PreparingTrainingStack

#secondary_status_transitionsArray<Types::SecondaryStatusTransition>

A history of all of the secondary statuses that the training job has transitioned through.

Returns:

#stopping_conditionTypes::StoppingCondition

Specifies a limit to how long a model training job can run. It also specifies the maximum time to wait for a spot instance. When the job reaches the time limit, Amazon SageMaker ends the training job. Use this API to cap model training costs.

To stop a job, Amazon SageMaker sends the algorithm the SIGTERM signal, which delays job termination for 120 seconds. Algorithms can use this 120-second window to save the model artifacts, so the results of training are not lost.

Returns:

#training_end_timeTime

Indicates the time when the training job ends on training instances. You are billed for the time interval between the value of TrainingStartTime and this time. For successful jobs and stopped jobs, this is the time after model artifacts are uploaded. For failed jobs, this is the time when Amazon SageMaker detects a job failure.

Returns:

  • (Time)

    Indicates the time when the training job ends on training instances.

#training_job_arnString

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

Returns:

  • (String)

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

#training_job_nameString

Name of the model training job.

Returns:

  • (String)

    Name of the model training job.

#training_job_statusString

The status of the training job.

Amazon SageMaker provides the following training job statuses:

  • InProgress - The training is in progress.

  • Completed - The training job has completed.

  • Failed - The training job has failed. To see the reason for the failure, see the FailureReason field in the response to a DescribeTrainingJobResponse call.
