Yes.
1.Make sure your GCC >= 4.9 for pytorch c++ Extensions;
Instructions for installing GCC >= 4.9: [https://gist.github.com/goldsborough/d466f43e8ffc948ff92de7486c5216d6]
2. Your pytorch was compiled with _GLIBCXX_USE_CXX11_ABI=1, but your c++ Extension was compiled with _GLIBCXX_USE_CXX11_ABI=0, or the opposite.
see your pytorch whether built with CXX_ABI=1 or 0 via torch._C._GLIBCXX_USE_CXX11_ABI.
My pytorch showed torch._C._GLIBCXX_USE_CXX11_ABI=True, then I insall pytorch by 'conda install pytorch torchvision cudatoolkit=9.0 -c pytorch' , this version's 'torch._C._GLIBCXX_USE_CXX11_ABI' is False. Finally, 'rm -r build' and build again.
