problem when compiling iou3d and roipool3d in Windows

I have compiled the codes of iou3d and roipool3d in Ubuntu successfully, but when I tried to compiled iou3d in Windows, the error occurred that showed ‘identifier “EPS” is undefined in device code’. Thus, I change the code like below.

//#define DEBUG
const int THREADS_PER_BLOCK_NMS = sizeof(unsigned long long) * 8;
//const float EPS = 1e-8;
#define EPS 1e-8

However, I met another problem

iou3d.obj : error LNK2001: 无法解析的外部符号 "public: long * __cdecl at::Tensor::data<long>(void)const " (??$data@J@Tensor@at@@QEBAPEAJXZ)
build\lib.win-amd64-3.6\iou3d_cuda.cp36-win_amd64.pyd : fatal error LNK1120: 1 个无法解析的外部命令
error: command 'C:\\Program Files (x86)\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1120

Anyone know how to solve it?

I mean try to change long * keep_data = keep.data<long>();

To

Long long * keep_data = keep.data<long long>();

U need to change “keep.data”to <long long >

@candisjesus Thank you for your reply! However, there is no “at::tensor::data” in the codes that I want to compile(iou3d.cpp, iou3d_kernel.cu). I still have no idea how to deal with it.
