Quantizes then dequantizes a tensor.
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
)
Args |
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.
|
Returns |
A Tensor . Each element is the result of quantizing and dequantizing the
corresponding element of input .
