FakeQuantizeBase
class torch.quantization.fake_quantize.FakeQuantizeBase
Base fake quantize module Any fake quantize implementation should
   derive from this class.
Concrete fake quantize module should follow the same API. In
   forward, they will update the statistics of the observed Tensor and
   fake quantize the input. They should also provide a
   calculate_qparams function that computes the quantization
   parameters given the collected statistics.
