In torch-1.10.0-cu113, there are:
libtorch_cuda.so 
libtorch_cuda_cpp.so
libtorch_cpu.so

In torch-1.10.0 (which works for cu102), there are:
libtorch_cuda.so 
libtorch_cpu.so

So CUDA kernels are contained in libtorch_cuda.so. So what is the difference between libtorch_cuda.so and libtorch_cuda_cpp.so?
