Generator

create_training_job(self, config, wait_for_completion=True, print_log=True, check_interval=30, max_ingestion_time=None)[source]

Starts a model training job. After training completes, Amazon SageMaker saves the resulting model artifacts to an Amazon S3 location that you specify.

Parameters
  • config (dict) -- the config for training

  • wait_for_completion (bool) -- if the program should keep running until job finishes

  • check_interval (int) -- the time interval in seconds which the operator will check the status of any SageMaker job

  • max_ingestion_time (Optional[int]) -- the maximum ingestion time in seconds. Any SageMaker jobs that run longer than this will fail. Setting this to None implies no timeout for any SageMaker job.

Returns

A response to training job creation

create_tuning_job(self, config, wait_for_completion=True, check_interval=30, max_ingestion_time=None)[source]

Starts a hyperparameter tuning job. A hyperparameter tuning job finds the best version of a model by running many training jobs on your dataset using the algorithm you choose and values for hyperparameters within ranges that you specify. It then chooses the hyperparameter values that result in a model that performs the best, as measured by an objective metric that you choose.

Parameters
  • config (dict) -- the config for tuning

  • wait_for_completion (bool) -- if the program should keep running until job finishes

  • check_interval (int) -- the time interval in seconds which the operator will check the status of any SageMaker job

  • max_ingestion_time (Optional[int]) -- the maximum ingestion time in seconds. Any SageMaker jobs that run longer than this will fail. Setting this to None implies no timeout for any SageMaker job.

Returns

A response to tuning job creation

create_transform_job(self, config, wait_for_completion=True, check_interval=30, max_ingestion_time=None)[source]

Starts a transform job. A transform job uses a trained model to get inferences on a dataset and saves these results to an Amazon S3 location that you specify.

Parameters
  • config (dict) -- the config for transform job

  • wait_for_completion (bool) -- if the program should keep running until job finishes

  • check_interval (int) -- the time interval in seconds which the operator will check the status of any SageMaker job

  • max_ingestion_time (Optional[int]) -- the maximum ingestion time in seconds. Any SageMaker jobs that run longer than this will fail. Setting this to None implies no timeout for any SageMaker job.

Returns

A response to transform job creation

create_processing_job(self, config, wait_for_completion=True, check_interval=30, max_ingestion_time=None)[source]

Use Amazon SageMaker Processing to analyze data and evaluate machine learning models on Amazon SageMaker. With Processing, you can use a simplified, managed experience on SageMaker to run your data processing workloads, such as feature engineering, data validation, model evaluation, and model interpretation.

Parameters
  • config (dict) -- the config for processing job

  • wait_for_completion (bool) -- if the program should keep running until job finishes

  • check_interval (int) -- the time interval in seconds which the operator will check the status of any SageMaker job

  • max_ingestion_time (Optional[int]) -- the maximum ingestion time in seconds. Any SageMaker jobs that run longer than this will fail. Setting this to None implies no timeout for any SageMaker job.

Returns

A response to transform job creation

create_model(self, config)[source]

Creates a model in Amazon SageMaker. In the request, you name the model and describe a primary container. For the primary container, you specify the Docker image that contains inference code, artifacts (from prior training), and a custom environment map that the inference code uses when you deploy the model for predictions.

Parameters

config (dict) -- the config for model

Returns

A response to model creation

create_endpoint_config(self, config)[source]

Creates an endpoint configuration that Amazon SageMaker hosting services uses to deploy models. In the configuration, you identify one or more models, created using the CreateModel API, to deploy and the resources that you want Amazon SageMaker to provision.

Parameters

config (dict) -- the config for endpoint-config

Returns

A response to endpoint config creation

create_endpoint(self, config, wait_for_completion=True, check_interval=30, max_ingestion_time=None)[source]

When you create a serverless endpoint, SageMaker provisions and manages the compute resources for you. Then, you can make inference requests to the endpoint and receive model predictions in response. SageMaker scales the compute resources up and down as needed to handle your request traffic.

Requires an Endpoint Config.
Parameters
  • config (dict) -- the config for endpoint

  • wait_for_completion (bool) -- if the program should keep running until job finishes

  • check_interval (int) -- the time interval in seconds which the operator will check the status of any SageMaker job

  • max_ingestion_time (Optional[int]) -- the maximum ingestion time in seconds. Any SageMaker jobs that run longer than this will fail. Setting this to None implies no timeout for any SageMaker job.

Returns

A response to endpoint creation

update_endpoint(self, config, wait_for_completion=True, check_interval=30, max_ingestion_time=None)[source]

Deploys the new EndpointConfig specified in the request, switches to using newly created endpoint, and then deletes resources provisioned for the endpoint using the previous EndpointConfig (there is no availability loss).

Parameters
  • config (dict) -- the config for endpoint

  • wait_for_completion (bool) -- if the program should keep running until job finishes

  • check_interval (int) -- the time interval in seconds which the operator will check the status of any SageMaker job

  • max_ingestion_time (Optional[int]) -- the maximum ingestion time in seconds. Any SageMaker jobs that run longer than this will fail. Setting this to None implies no timeout for any SageMaker job.
