be shared between
different layers. A typical situation where that happens is when the output of multiple branches of a residual topology are summed together
at high-precision, without requantizing first. In that case, the weight tensors of the layers that feed into the accumulator
need to have the same scale factor. That can be accomplished by declaring a single <cite>WeightQuantProxy</cite> that is shared among multiple layers.
What happens is that - for example for <cite>ScalingImplType.STATS</cite>, <ci
