Represents the quantization parameters for a list of named tensors.

• repeated QuantizationInfo.QuantParams entries = 1

  List of quantization parameters for tensors.

Affine parameters to quantize the per axis value. The metadata of the target properties should be specified as well.

Used in: PerAxisParams

• float scale = 1

• int32 zero_point = 2

The metadata defines the target properties.

Used in: QuantParams

• int32 num_bits = 1

  Bit number of fixed-point data the target kernel supports.

• int32 quantize_axis = 2

  The quantized axis index if it is per-axis quantization.

• int32 range_min = 3

  The minimum allowed value of the fixed-point data range. This can also be used to derive the sign of storage type.

• int32 range_max = 4

  The minimum allowed value of the fixed-point data range.

min/max of the per axis value range. To quantize the value, the metadata of the target properties should be specified or read from the ops quantization specification.

Used in: PerAxisParams

• float min = 1

• float max = 2

Params to quantize the axis. Only one of the field can be used.

Used in: QuantParams

• oneof params_oneof

  • MinMax min_max = 1

    min/max of the ranges.

  • AffineParams affine_params = 2

    affine parameters to quantize the per axis value.

The quantization parameters for a named tensor.

Used in: QuantizationInfo

• oneof name_oneof

  The tensor name has the following convention: tensor_name := op_name | op_name ’:’ port_number. If the op has only one port, op_name can be used. If the op has internal states, such as fused LSTM, the port_number should follow a predefined convention.

  • string name = 1

  • string name_regex = 2

    An regex can be used to match multiple tensors.

• repeated PerAxisParams params = 3

  The quantization parameters for the tensor. If it is for per-axis, the parameters should be defined for each axis, otherwise, if it is for per-tensor, this repeated field should only contain a single element.

• optional Metadata meta = 5

  Metadata about the quantization parameters.
