Win10 platform installation encountered an error caused by macro definition

[huang229]

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!

@ajtulloch I hope you can help me, thank you!

This is a dumb fix, but if you revert back to a commit on the master branch from a couple of months ago, you will be able to build it. Hash 2ec84eb worked for me, for example.

I doubt we're going to get much support from the apex team due to their stance on Windows support. If I find some time I'll dig in and see if I can figure out what is causing the issue. It seems like you simply need to find the offending code and add in the define.

Please try my forked version: https://github.com/kezewang/apex.
Moreover, please refer to the following link to fix Windows MSVC Compatibility
facebookresearch/pytorch3d#10

It costs me a whole day to address all the issues.

It works - thanks!
