Hi @Vasiliy_Kuznetsov. I too want to quantize a pretrained FasterRCNN model with MobilnetV3 backbone, but I don’t know where to start. Do I have to make a copy of and modify the original source code here? Let’s say I modified the MobileNetV3 backbone and added necessary “quant” lines, what changes do I need to make in the object detector part (RoiHeads, RPN, etc)? Thank you.
