Fake-quantize the 'inputs' tensor, type float to 'outputs' tensor of same type.
tf.raw_ops.FakeQuantWithMinMaxArgs(
inputs, min=-6, max=6, num_bits=8, narrow_range=False, name=None
)
Attributes [min; max] define the clamping range for the inputs data.
inputs values are quantized into the quantization range ([0; 2^num_bits - 1]
when narrow_range is false and [1; 2^num_bits - 1] when it is true) and
then de-quantized and output as floats in [min; max] interval.
num_bits is the bitwidth of the quantization; between 2 and 16, inclusive.
Before quantization, min and max values are adjusted with the following
logic.
It is suggested to have min <= 0 <= max. If 0 is not in the range of values,
the behavior can be unexpected:
If 0 < min < max: min_adj = 0 and max_adj = max - min.
If min < max < 0: min_adj = min - max and max_adj = 0.
If min <= 0 <= max: scale = (max - min) / (2^num_bits - 1),
min_adj = scale * round(min / scale) and max_adj = max + min_adj - min.
Quantization is called fake since the output is still in floating point.
