Perform quantization on Tensor input.
tf.raw_ops.UniformQuantize(
    input,
    scales,
    zero_points,
    Tout,
    quantization_min_val,
    quantization_max_val,
    quantization_axis=-1,
    name=None
)
Given input, scales and zero_points, performs quantization using the formula:
quantized_data = floor(input_data * (1.0f / scale) + 0.5f) + zero_point
Args | |
|---|---|
input
 | 
A Tensor. Must be one of the following types: float32.
Must be a Tensor of Tin.
 | 
scales
 | 
A Tensor of type float32.
The float value(s) to use as scale(s) to quantize input.
Must be a scalar Tensor if quantization_axis is -1 (per-tensor quantization), otherwise 1D Tensor of size (input.dim_size(quantization_axis),) (per-axis quantization).
 | 
zero_points
 | 
A Tensor of type int32.
The int32 value(s) to use as zero_point(s) to quantize input.
Same shape condition as scales.
 | 
Tout
 | 
A tf.DType from: tf.qint8, tf.qint32.
The type of output Tensor. A tf.DType from: tf.float32
 | 
quantization_min_val
 | 
An int.
The quantization min value to quantize input.
The purpose of this attribute is typically (but not limited to) to indicate narrow range, where this is set to:
(Tin lowest) + 1 if narrow range, and (Tin lowest) otherwise.
For example, if Tin is qint8, this is set to -127 if narrow range quantized or -128 if not.
 | 
quantization_max_val
 | 
An int.
The quantization max value to quantize input.
The purpose of this attribute is typically (but not limited to) indicate narrow range, where this is set to:
(Tout max) for both narrow range and not narrow range.
For example, if Tin is qint8, this is set to 127.
 | 
quantization_axis
 | 
An optional int. Defaults to -1.
Indicates the dimension index of the tensor where per-axis quantization is applied for the slices along that dimension.
If set to -1 (default), this indicates per-tensor quantization. Otherwise, it must be set within range [0, input.dims()).
 | 
name
 | 
A name for the operation (optional). | 
Returns | |
|---|---|
A Tensor of type Tout.
