common.datasets

Dataset loading utilities.

Classes

Name	Description
TrainDatasetMeta	Dataclass with fields for training and validation datasets and metadata.

TrainDatasetMeta

common.datasets.TrainDatasetMeta(
    self,
    train_dataset,
    eval_dataset=None,
    total_num_steps=None,
)

Dataclass with fields for training and validation datasets and metadata.

Functions

Name	Description
load_datasets	Loads one or more training or evaluation datasets, calling
load_preference_datasets	Loads one or more training or evaluation datasets for RL training using paired
sample_dataset	Randomly sample `num_samples` samples from `dataset`.

load_datasets

common.datasets.load_datasets(cfg, cli_args)

Loads one or more training or evaluation datasets, calling axolotl.utils.data.prepare_dataset. Optionally, logs out debug information.

Parameters

Name	Type	Description	Default
cfg	DictDefault	Dictionary mapping `axolotl` config keys to values.	required
cli_args	Union[PreprocessCliArgs, TrainerCliArgs]	Command-specific CLI arguments.	required

Returns

Name	Type	Description
	TrainDatasetMeta	Dataclass with fields for training and evaluation datasets and the computed
	TrainDatasetMeta	`total_num_steps`.

load_preference_datasets

common.datasets.load_preference_datasets(cfg, cli_args)

Loads one or more training or evaluation datasets for RL training using paired preference data, calling axolotl.utils.data.rl.load_prepare_preference_datasets. Optionally, logs out debug information.

Parameters

Name	Type	Description	Default
cfg	DictDefault	Dictionary mapping `axolotl` config keys to values.	required
cli_args	Union[PreprocessCliArgs, TrainerCliArgs]	Command-specific CLI arguments.	required

Returns

Name	Type	Description
	TrainDatasetMeta	Dataclass with fields for training and evaluation datasets and the computed
	TrainDatasetMeta	`total_num_steps`.

sample_dataset

common.datasets.sample_dataset(dataset, num_samples)

Randomly sample num_samples samples from dataset.

Parameters

Name	Type	Description	Default
dataset	Dataset	Dataset.	required
num_samples	int	Number of samples to return.	required

Returns

Name	Type	Description
	Dataset	Random sample (with replacement) of examples in `dataset`.
