FusedMovingAvgObsFakeQuantize¶
- class torch.ao.quantization.fake_quantize.FusedMovingAvgObsFakeQuantize(observer=<class 'torch.ao.quantization.observer.MovingAverageMinMaxObserver'>, quant_min=0, quant_max=255, **observer_kwargs)[source][source]¶
Define a fused module to observe the tensor.
Fused module that is used to observe the input tensor (compute min/max), compute scale/zero_point and fake_quantize the tensor. This module uses calculation similar MovingAverageMinMaxObserver for the inputs, to compute the min/max values in order to compute the scale/zero_point. The qscheme input in the observer is used to differentiate between symmetric/affine quantization scheme.
The output of this module is given by x_out = (clamp(round(x/scale + zero_point), quant_min, quant_max)-zero_point)*scale
Similar to
FakeQuantize, and accepts the same attributes as the base class.
