显示支持的cuda版本为11.4

2.去nvidia官网下载最新的cuda11.4.2

wget https://developer.download.nvidia.com/compute/cuda/11.4.2/local_installers/cuda_11.4.2_470.57.02_linux.run
sudo sh cuda_11.4.2_470.57.02_linux.run

出来提示后，依次操作

 1.是否接受EULA？   输入accept
 2.cuda安装？   选择不安装驱动，其他默认安装install
 直至安装完成

添加环境变量：

gedit ~/.bashrc

cuDNN Library for Linux (x86_64)
