def export(self, prepared_ldf: PreparedLDF):
overrides luxonis_ml.data.exporters.BaseExporter.export

Convert the prepared dataset into the exporter's format.

Parameters
prepared_ldf:PreparedLDFDataset data prepared for export.
Raises
NotImplementedErrorAlways raised by the abstract base implementation.
def supported_ann_types(self) -> list[str]:
overrides luxonis_ml.data.exporters.BaseExporter.supported_ann_types

Return task types supported by this exporter.

Returns
list[str]Supported annotation task types.
Raises
NotImplementedErrorAlways raised by the abstract base implementation.

Undocumented

@staticmethod
def _estimate_xml_size(objects: list[dict[str, Any]]) -> int:

Approximate byte-count.

The alternative is to serialize, pretty-print and discard every time just to compute the true xml size.

def _dump_annotations(self, per_split_data: dict[str, dict[str, dict[str, Any]]], output_path: Path, part: int | None = None):
overrides luxonis_ml.data.exporters.BaseExporter._dump_annotations

Undocumented

def _get_data_path(self, output_path: Path, split_name: str, part: int | None = None) -> Path:
overrides luxonis_ml.data.exporters.BaseExporter._get_data_path

Return the folder path to store data files for this split.
