How can I get the scale of the QAdaptiveActivation layer

As shown in the comment, the QAdaptiveActivation layer can be used to calculate the EMA of min and max of the activation values, i.e., the quantization range of the activations tensor.
After we have the quantization range and the number of quantization levels (e.g., 256 for INT8), we can get the scale.
However, I did not find the **_scale_** attribute in the QAdaptiveActivation layer.

So how can I get the **_scale_** of the QAdaptiveActivation layer?

Start by locating the QAdaptiveActivation layer implementation and reviewing how it tracks the EMA-based activation range and quantization levels. Determine how the layer’s scale should be exposed or retrieved, and verify that the resulting behavior is documented or covered by the project’s existing checks.
