Hi @ResidentMario, that’s a good point.  You can check out the definition of the function here: https://github.com/pytorch/pytorch/blob/20ac7362009dd8e0aca6e72fc9357773136a83b8/torch/quantization/qconfig.py#L81 2.  Filed https://github.com/pytorch/pytorch/issues/48106 3 to track adding it to the docs.
