How to install Cuda installer for 12.1 in windows 10

1

I am trying to install cuda binary in my Windows 10 computer (Dell computer).
In the past month I was able to install cuda11.7 and torch was compiled with that and it was working.

Now, I would like to use cuda12.1 with newer version of torch. But, when I try to install cuda 12.1, the installer file does not work.

Your issue seems to be unrelated to PyTorch so you might want to post it into an NVIDIA-specific discussion board.
With that being said, the PyTorch binaries ship with their own CUDA dependencies and your locally installed CUDA toolkit will be used if you build PyTorch from source or a custom CUDA extension. You would need to properly install an NVIDIA driver to be able to use your GPU.
