Can i quantize sigmoid activation (to QLinearSigmoid for example) in dynamic quantization?

[mattam301]

[Enter feedback here] Since i am trying to quantize efficientnet using both static and dynamic methods, then i realize that only the static one quantize sigmoid activation into: QuantizeLinear -> QlinearSigmoid_

But when i am trying to quantize using dynamic method, it turned out that sigmoid function cannot be quantized in default. As i read in quantize.py code, I cannot specify quant_format in DynamicQuantConfig, which seems lead to the above observation.

I wander what did i miss? Is there any reason why sigmoid cannot be quantized in dynamic method? Thanks in advance

Can you share the way you try to quantize your model and the error you get? That would help up to replicate and fix the bug if there is one.
