2.安装

sh cuda_11.8.0_520.61.05_linux.run 

直接accept

移动上下到driver上，再enter一下取消driver的更新

更新一下.bashrc，cp -r ~/.bashrc  xxx

source ~/.bashrc

export PATH=/usr/local/cuda-11.8/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-11.8/lib64:$LD_LIBRARY_PATH
export PATH=/home/miniconda3/bin:$PATH
. /home/miniconda3/etc/profile.d/conda.sh
conda activate

一般安装完路径就在/usr/local目录下，更新驱动需要重新启动reboot，只更新cuda不需要重新启动。
