SubIndexedBatch
¶
SubIndexedBatch(batch: BatchBase[BatchT, BArrayType, BDeviceType, BDtypeType, BRNGType], sub_indexes: Union[IndexableType, BArrayType])
Bases: BatchBase[BatchT, BArrayType, BDeviceType, BDtypeType, BRNGType]
A batch that offers a view of the original batch with a fixed index range. This does not support batch extension.
append_flattened
¶
append_flattened(value: BArrayType) -> None
Append one flattened sample to the batch.
remove_at
¶
remove_at(idx: Union[IndexableType, BArrayType]) -> None
Remove one or more samples from the batch.
extend_from
¶
extend_from(other: BatchBase[BatchT, BArrayType, BDeviceType, BDtypeType, BRNGType], chunk_size: int = 8, tqdm: bool = False) -> None
Copy data from another batch in bounded-size chunks.
get_slice
¶
get_slice(idx: Union[IndexableType, BArrayType]) -> BatchBase[BatchT, BArrayType, BDeviceType, BDtypeType, BRNGType]
Create a lazy view over a subset of indices.
get_column
¶
get_column(nested_keys: Sequence[str]) -> BatchBase[Any, BArrayType, BDeviceType, BDtypeType, BRNGType]
Create a lazy view over a nested field inside each sample.
