Better Compatibility for __CUDA_ARCH__ for RTX GPUs

[BICHENG]

at rasterize_cuda_kernel.cu
you need to change
#if CUDA_ARCH < 600 and defined(__CUDA_ARCH__)
//blablabla
#endif
to

#if !defined(__CUDA_ARCH__) || __CUDA_ARCH__ >= 600
#else
static __inline__ __device__ double atomicAdd(double* address, double val) {
    unsigned long long int* address_as_ull = (unsigned long long int*)address;
    unsigned long long int old = *address_as_ull, assumed;
    do {
        assumed = old;
        old = atomicCAS(address_as_ull, assumed,
                __double_as_longlong(val + __longlong_as_double(assumed)));
    // Note: uses integer comparison to avoid hang in case of NaN (since NaN != NaN) } while (assumed != old);
    } while (assumed != old);
    return __longlong_as_double(old);
}
#endif

it will solve setup.py nvcc call errors somehow

Thanks God
You're a lifesaver

My RTX 2080 can work now

Hello I applied the changes to rasterize_cuda_kernel.cu

Machine specs:
RTX-30
cuda 11.2

pip env:
torch==1.4.0
torchvision==0.5.0

But I still get this error:
