I cannot find FilterDescriptor::set() in libtorch.so

C++
1

I cannot find at::native::FilterDescriptor::set(at::Tensor const&, long) in the libtorch.so file.

The linker gives error message:

undefined reference to `at::native::FilterDescriptor::set(at::Tensor const&, long)'

But I do find this function in pytorch/aten/src/ATen/cudnn/Descriptors.cpp

What’s the problem?
