Hi Ding, First it looks like errors when running the demo. So it does compile; it encounters a just-in-time compilation error because cuda_runtime.h and curand_kernel.h are not found, right?
CUDA13 branch has some critical new updates today. So I'd suggest you use the newest code (do a pull now), then recompile using an empty folder from scratch, and try again. If the problem persists, please let me know and if so, I'm pretty sure it's on Windows platform only and some further testing on my side is needed...
