Model Inference Step Configuration with Self-Contained Derivation Logic

This module implements the configuration class for the XGBoost model inference step 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)

Configuration for XGBoost model inference step with self-contained derivation logic.

This class defines the configuration parameters for the XGBoost model inference step, which generates predictions from trained models without computing evaluation metrics. This is designed for pure inference workflows where predictions are needed for downstream processing (e.g., model calibration, batch scoring).

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)

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

classmethod validate_output_format(v)

Validate output format is supported.

classmethod validate_json_orient(v)

Validate JSON orientation is supported.

initialize_derived_fields()

Initialize all derived fields once after validation.

validate_inference_config()

Additional validation specific to inference configuration

get_environment_variables()

Get environment variables for the model inference 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 inference-specific fields. Gets a dictionary of public fields suitable for initializing a child config. Includes both base fields (from parent) and inference-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.
