tf.quantization.quantize_and_dequantize(
    input, input_min, input_max, signed_input=True, num_bits=8, range_given=False,
    round_mode='HALF_TO_EVEN', name=None, narrow_range=False
)

input A Tensor to quantize and dequantize.
input_min If range_given=True, the minimum input value that needs to be represented in the quantized representation.
input_max If range_given=True, the maximum input value that needs to be represented in the quantized representation.
signed_input True if the quantization is signed or unsigned.
num_bits The bitwidth of the quantization.
range_given If true use input_min and input_max for the range of the input, otherwise determine min and max from the input Tensor.
round_mode Rounding mode when rounding from float values to quantized ones.
name Optional name for the operation.
narrow_range 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.

A Tensor. Each element is the result of quantizing and dequantizing the corresponding element of input.
