ubuntu16.04安装多个版本CUDA的方法

    我的机器是CUDA16.04的,之前装过CUDA10.0,因为一些原因,现在需要安转CUDA9.0。

    1.首先https://developer.nvidia.com/cuda-90-download-archive?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604&target_type=runfilelocal

    下载run版本的(如果之前没装过CUDA,可以下载deb版本的)

    2.按照上面的教程

    
    sudo chmod +x cuda_9.0.176_384.81_linux.run # 为 cuda_9.0.176_384.81_linux.run 添加可执行权限 
    ./cuda_9.0.176_384.81_linux.run # 安装 cuda_9.0.176_384.81_linux.run

    3.相关参数的设置

    
    Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?
    (y)es/(n)o/(q)uit: n #我已经装过CUDA10了,所以不需要安转9.0的显卡驱动
    Install the CUDA 9.0 Toolkit? 
    (y)es/(n)o/(q)uit: y
    /usr/local/cuda-9.0 is not writable. 
    Do you wish to run the installation with 'sudo'? (y)es/(n)o: y #使用超级用户权限
    Please enter your password: Do you want to install a symbolic link at /usr/local/cuda? # 是否将安装目录通过软连接的方式 link 到 /usr/local/cuda,yes or no 都可以,取决于你是否使用 /usr/local/cuda 为默认的 cuda 目录。 
    (y)es/(n)o/(q)uit: y #我目前需要使用9.0
    Enter Toolkit Location
    [ default is /usr/local/cuda-9.0 ]:#直接回车

    4.安转结束后相关环境变量的设置

    
    Finished copying samples.
    ===========
    = Summary =
    ===========
    Driver: Not Selected
    Toolkit: Installed in /usr/local/cuda-9.0
    Samples: Installed in /usr/local/cuda-9.0/Samples
    Please make sure that
     - PATH includes /usr/local/cuda-9.0/bin
     - LD_LIBRARY_PATH includes /usr/local/cuda-9.0/lib64, or, add /usr/local/cuda-9.0/lib64 to /etc/ld.so.conf and run ldconfig as root
    To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-9.0/bin
    Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-9.0/doc/pdf for detailed information on setting up CUDA.
    ***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 384.00 is required for CUDA 9.0 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 /tmp/cuda_install_11003.log

    如上,需要设置PATH和LD_LIBRARY_PATH两个变量,在./bashrc文件中修改即可,记得要source一些./bashrc,让其生效。

    完成上面这些步骤后,就可以进行多个版本的切换了,直接修改/usr/local/cuda即可,使其指向不同版本的CUDA。
