Properties for creating an Amazon SageMaker training job.

Parameters

comment (Optional[str]) – An optional description for this state. Default: - No comment
heartbeat (Optional[Duration]) – Timeout for the heartbeat. Default: - None
input_path (Optional[str]) – JSONPath expression to select part of the state to be the input to this state. May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}. Default: - The entire task input (JSON path ‘$’)
integration_pattern (Optional[IntegrationPattern]) – AWS Step Functions integrates with services directly in the Amazon States Language. You can control these AWS services using service integration patterns Default: IntegrationPattern.REQUEST_RESPONSE
output_path (Optional[str]) – JSONPath expression to select select a portion of the state output to pass to the next state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: - The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path ‘$’)
result_path (Optional[str]) – JSONPath expression to indicate where to inject the state’s output. May also be the special value JsonPath.DISCARD, which will cause the state’s input to become its output. Default: - Replaces the entire input with the result (JSON path ‘$’)
result_selector (Optional[Mapping[str, Any]]) – The JSON that will replace the state’s raw result and become the effective result before ResultPath is applied. You can use ResultSelector to create a payload with values that are static or selected from the state’s raw result. Default: - None
timeout (Optional[Duration]) – Timeout for the state machine. Default: - None
algorithm_specification (AlgorithmSpecification) – Identifies the training algorithm to use.
input_data_config (Sequence[Channel]) – Describes the various datasets (e.g. train, validation, test) and the Amazon S3 location where stored.
output_data_config (OutputDataConfig) – Identifies the Amazon S3 location where you want Amazon SageMaker to save the results of model training.
training_job_name (str) – Training Job Name.
enable_network_isolation (Optional[bool]) – Isolates the training container. No inbound or outbound network calls can be made to or from the training container. Default: false
hyperparameters (Optional[Mapping[str, Any]]) – Algorithm-specific parameters that influence the quality of the model. Set hyperparameters before you start the learning process. For a list of hyperparameters provided by Amazon SageMaker Default: - No hyperparameters
resource_config (Optional[ResourceConfig]) – Specifies the resources, ML compute instances, and ML storage volumes to deploy for model training. Default: - 1 instance of EC2 M4.XLarge with 10GB volume
role (Optional[IRole]) – Role for the Training Job. The role must be granted all necessary permissions for the SageMaker training job to be able to operate. See https://docs.aws.amazon.com/fr_fr/sagemaker/latest/dg/sagemaker-roles.html#sagemaker-roles-createtrainingjob-perms Default: - a role will be created.
stopping_condition (Optional[StoppingCondition]) – Sets a time limit for training. Default: - max runtime of 1 hour
tags (Optional[Mapping[str, str]]) – Tags to be applied to the train job. Default: - No tags
vpc_config (Optional[VpcConfig]) – Specifies the VPC that you want your training job to connect to. Default: - No VPC
