REQUIRED AlgorithmSpecification => Paws::SageMaker::AlgorithmSpecification

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

REQUIRED CreationTime => Str

A timestamp that indicates when the training job was created.

EnableInterContainerTrafficEncryption => Bool

To encrypt all communications between ML compute instances in distributed training, specify True. Encryption provides greater security for distributed training, but training take longer because of the additional communications between ML compute instances.

EnableNetworkIsolation => Bool

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.

FailureReason => Str

If the training job failed, the reason it failed.

FinalMetricDataList => ArrayRef[Paws::SageMaker::MetricData]

A collection of MetricData objects that specify the names, values, and dates and times that the training algorithm emitted to Amazon CloudWatch.

HyperParameters => Paws::SageMaker::HyperParameters

Algorithm-specific parameters.

InputDataConfig => ArrayRef[Paws::SageMaker::Channel]

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

LabelingJobArn => Str

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

LastModifiedTime => Str

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

REQUIRED ModelArtifacts => Paws::SageMaker::ModelArtifacts

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

OutputDataConfig => Paws::SageMaker::OutputDataConfig

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

REQUIRED ResourceConfig => Paws::SageMaker::ResourceConfig

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

RoleArn => Str

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

REQUIRED SecondaryStatus => Str

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:

  • 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.

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

  • Completed - The training job has completed.

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

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

  • Stopped - The training job has stopped.

  • Stopping - Stopping the training job.

Valid values for SecondaryStatus are subject to change.

We no longer support the following secondary statuses:

  • LaunchingMLInstances

  • PreparingTrainingStack

  • DownloadingTrainingImage

Valid values are: "Starting", "LaunchingMLInstances", "PreparingTrainingStack", "Downloading", "DownloadingTrainingImage", "Training", "Uploading", "Stopping", "Stopped", "MaxRuntimeExceeded", "Completed", "Failed" =head2 SecondaryStatusTransitions => ArrayRef[Paws::SageMaker::SecondaryStatusTransition]

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

REQUIRED StoppingCondition => Paws::SageMaker::StoppingCondition

The condition under which to stop the training job.

TrainingEndTime => Str

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.

REQUIRED TrainingJobArn => Str

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

REQUIRED TrainingJobName => Str

Name of the model training job.

REQUIRED TrainingJobStatus => Str

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.

  • Stopping - The training job is stopping.

  • Stopped - The training job has stopped.

For more detailed information, see SecondaryStatus.

Valid values are: "InProgress", "Completed", "Failed", "Stopping", "Stopped" =head2 TrainingStartTime => Str

Indicates the time when the training job starts on training instances. You are billed for the time interval between this time and the value of TrainingEndTime. The start time in CloudWatch Logs might be later than this time. The difference is due to the time it takes to download the training data and to the size of the training container.

TuningJobArn => Str

The Amazon Resource Name (ARN) of the associated hyperparameter tuning job if the training job was launched by a hyperparameter tuning job.

VpcConfig => Paws::SageMaker::VpcConfig

A VpcConfig object that specifies the VPC that this training job has access to. For more information, see Protect Training Jobs by Using an Amazon Virtual Private Cloud (

_request_id => Str
