Unborn安装CUDA Toolkit

前言

今天在某台Unborn系统上安装某个依赖库时，提示环境中缺少CUDA_HOME环境变量，导致在安装某些依赖时出现问题。具体异常如下：

下载

访问https://developer.nvidia.com/cuda-toolkit-archive

执行nvidia-smi命令，查看GPU的驱动与CUDA版本

由于GPU自身CUDA版本是12.2，因此这里选择下载CUDA Toolkit 12.2。

这里选择：Linux系统、x86_64架构、Ubuntu系统、系统版本22.04、runfile(local)安装方式

同时页面下方也给出了安装说明

安装

下载与执行安装

wget https://developer.download.nvidia.com/compute/cuda/12.2.0/local_installers/cuda_12.2.0_535.54.03_linux.runsudo sh cuda_12.2.0_535.54.03_linux.run

选择Continue后回车

输入accept接受

取消Drive驱动的安装，默认勾选（x），取消后选择Install进行安装。

出现如下日志，表示安装成功

===========

===========Driver:   Not Selected
Toolkit:  Installed in /usr/local/cuda-12.2/Please make sure that-   PATH includes /usr/local/cuda-12.2/bin-   LD_LIBRARY_PATH includes /usr/local/cuda-12.2/lib64, or, add /usr/local/cuda-12.2/lib64 to /etc/ld.so.conf and run ldconfig as rootTo uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-12.2/bin
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 535.00 is required for CUDA 12.2 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 --driverLogfile is /var/log/cuda-installer.log

配置

编辑vim ~/.bashrc文件,配置环境变量

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

验证

查看cuda是否安装成功
