Modality Defaults

Container providing default values used when a dataset does not ship a particular modality.

standard_e2e.dataset_utils.modality_defaults.ModalityDefaults

Base class for modality-specific default value handling on the fly.

Per-modality defaults:

standard_e2e.dataset_utils.modality_defaults.IntentDefaults	Provide default handling for the INTENT modality (fallback UNKNOWN).
standard_e2e.dataset_utils.modality_defaults.PreferredTrajectoryDefaults	Substitute missing preference trajectories with n empty trajectories.
standard_e2e.dataset_utils.modality_defaults.LidarPointCloudDefaults	Substitute a missing LIDAR_PC modality with an empty LidarPointCloud (xyz components, zero points).
standard_e2e.dataset_utils.modality_defaults.LidarBEVDefaults	Substitute a missing LIDAR_BEV modality with a zero tensor of the given (C, H, W) shape.
standard_e2e.dataset_utils.modality_defaults.HDMapBEVDefaults	Substitute a missing HD_MAP_BEV modality with a zero tensor of the given (C, H, W) shape.
