Do you mean in Windows bat script or windows install steps ?
If yes, this is because the default installation of onnxruntime and onnxruntime-gpu will install the version built for CUDA 11.x.
But just I mentioned in the ticket #15, my env is CUDA 12.1, and according to onnxruntime official doc here - https://onnxruntime.ai/docs/install/

the correct index for onnxruntime and command should be:
pip install onnxruntime-gpu --extra-index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-12/pypi/simple/
this is the reason why we need to unstall them first, then re-install by this link.

if your env is CUDA 11.8, I believe you don't need this step.
