| |
| The SKLearnProcessor handles Amazon SageMaker processing tasks for jobs using scikit-learn. |
| |
| Args: |
| framework_version (str): The version of scikit-learn. |
| role (str): An AWS IAM role name or ARN. The Amazon SageMaker training jobs |
| and APIs that create Amazon SageMaker endpoints use this role |
| to access training data and model artifacts. After the endpoint |
| is created, the inference code might use the IAM role, if it |
| needs to access an AWS resource. |
| instance_type (str or PipelineVariable): Type of EC2 instance to use for |
| processing, for example, 'ml.c4.xlarge'. |
| instance_count (int or PipelineVariable): The number of instances to run |
| the Processing job with. Defaults to 1. |
| command ([str]): The command to run, along with any command-line flags. |
| Example: ["python3", "-v"]. If not provided, ["python3"] or ["python2"] |
| will be chosen based on the py_version parameter. |
| volume_size_in_gb (int or PipelineVariable): Size in GB of the EBS volume to |
| use for storing data during processing (default: 30). |
| volume_kms_key (str or PipelineVariable): A KMS key for the processing |
| volume. |
| output_kms_key (str or PipelineVariable): The KMS key id for all ProcessingOutputs. |
| max_runtime_in_seconds (int or PipelineVariable): Timeout in seconds. |
| After this amount of time Amazon SageMaker terminates the job |
| regardless of its current status. |
| base_job_name (str): Prefix for processing name. If not specified, |
| the processor generates a default job name, based on the |
| training image name and current timestamp. |
| sagemaker_session (sagemaker.session.Session): Session object which |
| manages interactions with Amazon SageMaker APIs and any other |
| AWS services needed. If not specified, the processor creates one |
| using the default AWS configuration chain. |
| env (dict[str, str] or dict[str, PipelineVariable]): Environment variables |
| to be passed to the processing job. |
| tags (list[dict[str, str] or list[dict[str, PipelineVariable]]): List of tags |
| to be passed to the processing job. |
| network_config (sagemaker.network.NetworkConfig): A NetworkConfig |
| object that configures network isolation, encryption of |
| inter-container traffic, security group IDs, and subnets. |
