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

Start 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

Returns

A response to training job creation

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

Start 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

Returns

A response to tuning job creation

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