config

optimus_dl.recipe.train.config

Training recipe configuration.

This module defines the configuration classes for the training recipe, including all hyperparameters, component configurations, and training settings.

TrainConfig dataclass

Bases: RegistryConfigStrict

Complete training configuration.

This is the root configuration class for training. It contains all component configurations (model, data, optimizer, etc.) and uses the registry system for flexible component selection.

The configuration is hierarchical and supports OmegaConf interpolation for sharing values across components. The args field serves as a "scratch space" for high-level variables that can be referenced throughout the config.

Example

config = TrainConfig(
    _name="base",
    args={"batch_size": 64, "seq_len": 1024},
    model=ModelConfig(_name="llama", n_embd=512),
    optimization=OptimizationConfig(
        batch_size="${args.batch_size}",
        lr=1e-4,
    ),
)

Parameters:

Name	Type	Description	Default
args	dict	dict() -> new empty dictionary dict(mapping) -> new dictionary initialized from a mapping object's (key, value) pairs dict(iterable) -> new dictionary initialized as if via: d = {} for k, v in iterable: d[k] = v dict(**kwargs) -> new dictionary initialized with the name=value pairs in the keyword argument list. For example: dict(one=1, two=2)	<class 'dict'>
common	TrainRecipeConfig	Configuration for training recipe common settings. This class contains all the common settings shared across training runs, including experiment metadata, logging frequency, checkpointing, evaluation, and distributed training settings.	<dynamic>
model	ModelConfig		'???'
data	DataConfig		'???'
criterion	CriterionConfig		'???'
optimization	OptimizationConfig		'???'
lr_scheduler	RegistryConfig | None		None
loggers	list[MetricsLoggerConfig] | None	List of metrics logger configurations	None
metrics	dict[str, list[dict]]	Metric configurations mapped by dataset name (e.g., 'train', 'val_slice_1')	<class 'dict'>
model_transforms	list[ModelTransformConfig]	List of model transforms to apply after model building	<dynamic>
model_builder	RegistryConfig		ModelBuilderConfig(_name='base')
optimizer_builder	RegistryConfig		OptimizerBuilderConfig(_name='base')
criterion_builder	RegistryConfig		CriterionBuilderConfig(_name='base')
data_builder	RegistryConfig		DataBuilderConfig(_name='base')
scheduler_builder	RegistryConfig		SchedulerBuilderConfig(_name='base')
logger_manager	RegistryConfig		LoggerManagerConfig(_name='base')
checkpoint_manager	RegistryConfig		CheckpointManagerConfig(_name='base')
evaluator	RegistryConfig		EvaluatorConfig(_name='base')
