Summary: Pull Request resolved: pytorch#11254 Previously we use DeviceType in caffe2.proto directly, but it's an `enum` and have implicit conversion to int, which does not have type safety, e.g. we have to explicitly check for a device type is valid in event.h: ``` template <int d> struct EventCreateFunctionRegisterer { explicit EventCreateFunctionRegisterer(EventCreateFunction f) { static_assert(d < MaxDeviceTypes, ""); Event::event_creator_[d] = f; } }; ``` at::DeviceType is an `enum class`, and it does not have implicit conversion to int, and provides better type safety guarantees. In this diff we have done the following refactor(taking CPU as an example): 1. caffe2::DeviceType → caffe2::DeviceTypeProto 2. caffe2::CPU → caffe2::PROTO_CPU 3. caffe2::DeviceType = at::DeviceType 4. caffe2::CPU = at::DeviceType::CPU codemod -d caffe2/caffe2 --extensions h,cc,cpp 'device_type\(\), ' 'device_type(), PROTO_' + some manual changes In short, after this diff, in c++, caffe2::CPU refers to the at::DeviceType::CPU and the old proto caffe2::CPU will be caffe2::PROTO_CPU. In python side, we have a temporary workaround that alias `caffe2_pb2.CPU = caffe2_pb2.PROOT_CPU` to make the change easier to review and this will be removed later.

[pt1][tensor] caffe2::DeviceType -> at::DeviceType
Previously we use DeviceType in caffe2.proto directly, but it's an
enumand have implicit conversion to int, which does not have type safety, e.g. we have to explicitly check for a device type is valid in event.h:at::DeviceType is an
enum class, and it does not have implicit conversion to int, and provides better type safety guarantees. In this diff we have done the following refactor(taking CPU as an example):codemod -d caffe2/caffe2 --extensions h,cc,cpp 'device_type(), ' 'device_type(), PROTO_'
In short, after this diff, in c++, caffe2::CPU refers to the at::DeviceType::CPU and the old proto caffe2::CPU will be caffe2::PROTO_CPU.
In python side, we have a temporary workaround that alias
caffe2_pb2.CPU = caffe2_pb2.PROOT_CPUto make the change easier to review and this will be removed later.Differential Revision: D9545704
