Detailed Documentation¶

ConvertQuantizeDequantize transformation replaces following graph: FakeQuantize->Convert->Convert->Subtract->Multiply with a single FakeQuantize. Restrictions:

quantized data type must be i8 or u8
‘levels’ attribute to FakeQuantize must be equal to 256
(output_low, output_high) must be (-128, 127) or (0, 256) (depends on sign of quantized data type)
‘zero_point’ and ‘scale’ must be broadcastable to FakeQuantize’s output
