查询目录https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html
因选用 CUDA 12.9
查询https://developer.nvidia.com/cuda-toolkit-archive（要登录的） 下载cuda toolkit 12.9 
cuda_12.9.0_576.02_windows.exe
查询https://developer.nvidia.com/rdp/cudnn-archive  下载cuda加速器  cuDNN

验证是否安装了cuda toolkit 12.2

安装pytorch
conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia
卸载pytorch
conda uninstall pytorch torchvision torchaudio
pip uninstall torch torchvision
查看cuda 是否安装
>>> import torch
>>> torch.cuda.is_available()
True
>>> torch.__version__
'2.5.1'   是cpu版本
