Hi, all, when I tried Extending torchscript with custom c++ operators as the instrument https://pytorch.org/tutorials/advanced/torch_script_custom_ops.html 7.
I compiled the C++ op succeed, but when I use it in pytorch, I got this error:
build/libwarp_perspective.so: undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

I think it is something error about C++11, because, I umcomment all the thing about Opencv, the error is still there.
anyone could help me? that very nice for you !!
