Quantization of Hybrid Pytorch Model

Hi,

I hope you are fine and doing well.
I have a pytorch model consists of Conv + Bi GRU + FC layer.
I have trained it and generated a pth file.

I want to quantize it, how to proceed? How to specify per channel quantization in Qconfig? And how to decide between symmetric or asymmetric quantization?

Any help will be very appreciable.
