I have been studying pytorch’s custom op registration. I noticed that there are these two classes used for registration. I am wondering why there isn’t a README for using TORCH_LIBRARY(), and what is the difference betweening using TORCH_LIBRARY(my_ops,m) and static auto registry = torch::RegisterOperators()
.op(“my_ops::myrelu”,  torch::RegisterOperators::options()
.kernel<decltype(myrelu), &myrelu>(c10::DispatchKey::CPU));
