furiosa.quantizer.frontend.onnx.calibrate module

class furiosa.quantizer.frontend.onnx.calibrate.CalibrationDataReaderForIterator(iterator: Iterator[Dict[str, numpy.ndarray]])

Bases: onnxruntime.quantization.calibrate.CalibrationDataReader

A CalibrationDataReader that wraps dicts mapping input tensor names to their values.

get_next()

generate the input data dict for ONNXinferenceSession run

exception furiosa.quantizer.frontend.onnx.calibrate.CalibrationError

Bases: Exception

The base class for all exceptions that are related to calibration.

furiosa.quantizer.frontend.onnx.calibrate.calibrate(model: onnx.onnx_ml_pb2.ModelProto, dataset: Iterable[Dict[str, numpy.ndarray]], augmented_model_path: Optional[str] = None) → Dict[str, Tuple[float, float]]

Estimates the range of tensors in a model, based on a dataset.

Parameters

• model – An ONNX model to calibrate.

• dataset – An Iterable that returns dicts mapping input tensor names to their values.

• augmented_model_path – A path to save an augmented model to.

Returns

A dict mapping tensors in the model to their minimum and maximum values.

furiosa.quantizer.frontend.onnx.calibrate.calibrate_with_random_data(model: onnx.onnx_ml_pb2.ModelProto, dataset_size: int = 8, augmented_model_path: Optional[str] = None) → Dict[str, Tuple[float, float]]

Estimates the range of tensors in a model, based on a random dataset.

Parameters

• model – An ONNX model to calibrate.

• dataset_size – the size of a random dataset to use.

• augmented_model_path – A path to save an augmented model to.

Returns

A dict mapping tensors in the model to their minimum and maximum values.

exception furiosa.quantizer.frontend.onnx.AlreadyQuantizedError(op_type: str)

Bases: ValueError

Exception raised if given model is partially quantized.

furiosa.quantizer.frontend.onnx.post_training_quantize(model: onnx.onnx_ml_pb2.ModelProto, dataset: Iterable[Dict[str, numpy.ndarray]], per_channel: bool = True, opset_version: int = 13) → onnx.onnx_ml_pb2.ModelProto

Post-training-quantizes an ONNX model with a calibration dataset.

Parameters

• model – An ONNX model to quantize.

• dataset – A calibration dataset.

• per_channel – If per_channel is True, Conv’s filters are per-channel quantized. Otherwise, they are per-tensor quantized.

• opset_version – ONNX OperatorSet version to use.

Returns

An ONNX model post-training-quantized with the calibration dataset.
