This module provides a placeholder implementation for dataset operations when the full training dataset dependencies are not available. Note: Full dataset functionality requires Text2MusicDataset which may not be included in the basic installation to reduce dependencies. )OptionalTupleAnyDictc2eZdZdZdZdedefdZdefdZy)DatasetHandlerz Dataset Handler for Dataset Explorer functionality.
