class espnet3.components.data.data_organizer.DatasetConfig(name: str, dataset: Dict[str, Any] = None, transform: Dict[str, Any] | None = None)

Bases: object

Configuration class for dataset metadata and construction.

This class encapsulates the necessary fields to define and instantiate a dataset. Used with Hydra to allow modular and flexible configuration via YAML or dictionaries.

name

Name identifier for the dataset.

• Type: str

path

Optional path or ID required for dataset instantiation.

• Type: Optional[str]

dataset

A dictionary for Hydra instantiation of the dataset.

• Type: Dict[str, Any]

transform

A dictionary for Hydra instantiation of a transform applied to each sample after loading.

• Type: Optional[Dict[str, Any]]

Example

>>> config_dict = {
...     "name": "custom",
...     "dataset": {
...         "_target_": "my_project.datasets.MyDataset",
...     },
...     "transform": {
...         "_target_": "my_project.transforms.uppercase_transform"
...     }
... }
>>> config = DatasetConfig(**config_dict)
