==========================================================================================
After updating my torch==2.5.1, torchvision==0.20.1, and torchaudio==2.5.1 (cu121), I encountered a compilation issue. Then, when I reinstalled "spatial_correlation_sampler", I got the error below. What could be the core issue? It was working fine with torch==2.3.1+cu121 before.

I am really looking forward to your reply, as this is very important to me.

To avoid the first warning, you can simply do pip install . instead of python setup.py install

Otherwise, it looks like error is this :

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.3\include\crt/host_config.h(164): fatal error C1189: #error: -- unsupported Microsoft Visual Studio version! Only the versions between 2017 and 2022 (inclusive) are supported! The nvcc flag '-allow-unsupported-compiler' can be used to override this version check; however, using an unsupported host compiler may cause compilation failure or incorrect run time execution. Use at your own risk.

So I'm not sure how it works for Windows, but I suppose there's a problem with the compiler chosen. What command di you use exactly ? And what does your environment looks like ?
