PerAxis#

class torch.ao.quantization.observer.PerAxis(axis)[source]#

Represents per-axis granularity in quantization.

This granularity type calculates different quantization parameters along a specified axis of the tensor.

For example if the input tensor is shape [8, 16] and axis=0, then the quantization parameters are calculated for each row of the tensor. Giving a total of 8 quantization parameters.

Variables

axis (int) – The axis along which reduction is performed.
