Thank you for the great work.
i want know how to use KNN,I set KNN-use to True in arch_cfg.yaml and infer
I've tested several sets of KNN parameters, but I don't even see a change after using KNN
By the way, this is my rangeview, I want to remove the blue dots and change them to yellow dots, can you give me some advice on how to do that.
