1. cuda 下载

在此处选择自己想要下载的 cuda 版本cuda-toolkit-archive

以 cuda 11.8 版本为例，按如图进行选择，我这里是 centos 系统，其它系统如实选择即可，这里选择 runfile 下载

network：网络安装包，安装包较小，需要在主机内联网下载实际的安装包
local：本地安装包。安装包较大，包含每一个下载安装组件的安装包

在页面下面有直接的安装命令，这里我的命令是

wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run
sudo sh cuda_11.8.0_520.61.05_linux.run

2. cuda 安装

执行第一条命令

执行第二条命令
我这边已经安装 cuda driver 了，所以我安装 cuda 就可以，其他的均不安装，按照如下选择

安装完后如下所示

(python) ➜  ~ sudo sh cuda_11.8.0_520.61.05_linux.run

===========
= Summary =
===========

Driver:   Not Selected
Toolkit:  Installed in /usr/local/cuda-11.8/

Please make sure that
 -   PATH includes /usr/local/cuda-11.8/bin
 -   LD_LIBRARY_PATH includes /usr/local/cuda-11.8/lib64, or, add /usr/local/cuda-11.8/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-11.8/bin
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 520.00 is required for CUDA 11.8 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
    sudo <CudaInstaller>.run --silent --driver

Logfile is /var/log/cuda-installer.log

也可以使用 --prefix 选项指定 CUDA Toolkit 的安装路径。例如，如果你想安装到 /opt/cuda-11.8，你可以运行：

sudo sh cuda_11.8.0_520.61.05_linux.run --silent --toolkit --toolkitpath=/opt/cuda-11.8

详细说明：

--silent：静默安装，不会出现交互式界面。
--toolkit：仅安装 CUDA Toolkit（不会安装驱动）。
--toolkitpath=/opt/cuda-11.8：将 CUDA Toolkit 安装到 /opt/cuda-11.8。

添加环境变量
vim ~/.zshrc，如果是 bash 的话 vim ~/.zshrc 修改为 vim ~/.bashrc，然后添加下面语句，保存后执行 source ~/.zshrc 即可修改成功
添加下面语句

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.8/lib64
export PATH=$PATH:/usr/local/cuda-11.8/bin
export CUDA_HOME=$CUDA_HOME:/usr/local/cuda-11.8

你的 CUDA 将会安装到指定路径 /usr/local/cuda-11.8，并且可以全局使用。🚀

3. 多 cuda 版本共存

只需要安装多个 cuda，然后修改环境变量为 xxx/cuda-xx.x 即可
