XGBoost Training Step Configuration with Self-Contained Derivation Logic

This module implements the configuration class for SageMaker XGBoost Training steps using a self-contained design where derived fields are private with read-only properties. Fields are organized into three tiers: 1. Tier 1: Essential User Inputs - fields that users must explicitly provide 2. Tier 2: System Inputs with Defaults - fields with reasonable defaults that can be overridden 3. Tier 3: Derived Fields - fields calculated from other fields (private with properties)

Bases: BasePipelineConfig

Configuration specific to the SageMaker XGBoost Training Step. This version is streamlined to work with specification-driven architecture. Input/output paths are now provided via step specifications and dependencies.

Fields are organized into three tiers: 1. Tier 1: Essential User Inputs - fields that users must explicitly provide 2. Tier 2: System Inputs with Defaults - fields with reasonable defaults that can be overridden 3. Tier 3: Derived Fields - fields calculated from other fields (private with properties)

model_config: ClassVar[ConfigDict] = {'arbitrary_types_allowed': True, 'extra': 'allow', 'protected_namespaces': (), 'validate_assignment': True}

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].

property hyperparameter_file: str

Get hyperparameter file path.

model_dump(**kwargs)

Override model_dump to include derived properties.

initialize_derived_fields()

Initialize all derived fields once after validation.

classmethod validate_job_type(v)

Validate job_type is one of allowed values.

get_environment_variables()

Get environment variables for the XGBoost training script.

Returns:

Dictionary mapping environment variable names to values

Return type:

Dict[str, str]

get_public_init_fields()

Override get_public_init_fields to include XGBoost training-specific fields. Gets a dictionary of public fields suitable for initializing a child config. Includes both base fields (from parent) and XGBoost training-specific fields.

Returns:

Dictionary of field names to values for child initialization

Return type:

Dict[str, Any]

get_job_arguments()

CLI args — config is the single source (FZ 31e1d3h).

model_post_init(context, /)

This function is meant to behave like a BaseModel method to initialize private attributes.

It takes context as an argument since that’s what pydantic-core passes when calling it.

Parameters:

• self (BaseModel) – The BaseModel instance.

• context (Any) – The context.
