Generator
- create_training_job(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 (int | None) – 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(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

check_interval (int) – the time interval in seconds which the operator will check the status of any SageMaker job
max_ingestion_time (int | None) – 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(config, wait_for_completion=True, check_interval=30, max_ingestion_time=None)[source]¶

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

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.
