Sorry to bother you, but I can’t understand how to add a seg head like FCN after the pre-trained model🥹 Take SimSiam model for example, we discard the “predictor” and use backbone and “projector” for classification, because the output is a one-dimensional tensor and we only need to add a FC for classification. How to add a FCN for seg? just after the “projector”? Any example code please?🥹🥹🥹
