This is almost identical to QuantizeAndDequantizeV2, except that it returns a
gradient of 1 for inputs that are within the quantization range, or 0 otherwise.
Args
input
A Tensor. Must be one of the following types: bfloat16, half, float32, float64.
Tensor to quantize and then dequantize.
input_min
A Tensor. Must have the same type as input.
If range_given == True, this specifies the minimum input value that needs to
be represented, otherwise it is determined from the min value of the input
tensor.
input_max
A Tensor. Must have the same type as input.
If range_given == True, this specifies the maximum input value that needs to
be represented, otherwise it is determined from the max value of the input
tensor.
signed_input
An optional bool. Defaults to True.
Whether the quantization is signed or unsigned. (actually this parameter should
have been called signed_output)
num_bits
An optional int. Defaults to 8.
The bitwidth of the quantization.
range_given
An optional bool. Defaults to False.
Whether the range is given or should be determined from the input tensor.
round_mode
An optional string from: "HALF_TO_EVEN", "HALF_UP". Defaults to "HALF_TO_EVEN".
The 'round_mode' attribute controls which rounding tie-breaking algorithm is
used when rounding float values to their quantized equivalents. The following
rounding modes are currently supported:
HALF_TO_EVEN: this is the default round_mode.
HALF_UP: round towards positive. In this mode 7.5 rounds up to 8 and -7.5
rounds up to -7.
narrow_range
An optional bool. Defaults to False.
If True, then the absolute value of the quantized minimum value is the same as
the quantized maximum value, instead of 1 greater.
i.e. for 8 bit quantization, the minimum value is -127 instead of -128.
axis
An optional int. Defaults to -1.
If specified, this axis is treated as a channel or slice axis, and a separate
quantization range is used for each channel or slice along this axis.
