按回车取消驱动安装

• gcc版本不兼容报错

 Failed to verify gcc version. See log at /var/log/cuda-installer.log for details.

这样就行，加一个--override

sudo sh cuda_10.2.89_440.33.01_linux.run --override

切换版本

首先查看当前cuda版本

ls /usr/local/

我们可以看到

bin  cuda-11.0  cuda-11.8  cuda-12.0  etc  games  include  lib  man  sbin  share  src

然后编辑环境变量

vim ~/.bashrc

最下面加入11.8的环境变量

## cuda path
cuda_version=11.8export PATH=/usr/local/cuda-$cuda_version/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-$cuda_version/lib64:$ld_library_path
export CUDA_HOME=/usr/local/cuda-$cuda_version

然后source一下

 source ~/.bashrc 

我们可以nvcc看下
