Description
My configuration is as follows:
win10
pytorch1.2.0
cuda10.0
vs2017
The installation command is as follows:
python setup.py install --cuda_ext --cpp_ext
Please tell me how to solve this problem, thank you!

D:/python-3.6.7/lib/site-packages/torch/include\c10/cuda/CUDAStream.h(171): warning: field of class type without a DLL interface used in a class with a DLL interface
D:/vs2017/VC/Tools/MSVC/14.16.27023/include\type_traits(1271): error: static assertion failed with "You've instantiated std::aligned_storage<Len, Align> with an extended alignment (in other words, Align > alignof(max_align_t)). Before VS 2017 15.8, the member type would non-conformingly have an alignment of only alignof(max_align_t). VS 2017 15.8 was fixed to handle this correctly, but the fix inherently changes layout and breaks binary compatibility (only for uses of aligned_storage with extended alignments). Please define either (1) _ENABLE_EXTENDED_ALIGNED_STORAGE to acknowledge that you understand this message and that you actually want a type with an extended alignment, or (2) _DISABLE_EXTENDED_ALIGNED_STORAGE to silence this message and get the old non-conformant behavior."

- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reproducing the python setup.py install --cuda_ext --cpp_ext build on the reported Windows, PyTorch, CUDA, and Visual Studio versions. Inspect csrc/multi_tensor_scale_kernel.cu around lines 25 and 64 and verify the build completes without the reported std::aligned_storage error; the issue is done when the installation succeeds or the supported configuration is documented.
