Ubuntu16.04下安装多版本cuda和cudnn

 i7-7700k + TITAN X + 16G DDR4 2400 + 256G SSD

ubuntu16.0.4+ anaconda3+ tensorflow-gpu(0.12.1)   

电脑已经安装CUDA9+ cuDNN7.1， 本次安装CUDA8.0.44 + cuDNN5.1

相关命令：

查看cuda版本 ：      nvcc -V

查看位置  ：            which nvcc

查看NVIDIA动态使用情况：  watch -n 1 nvidia-smi  

cuda 版本    ：    cat /usr/local/cuda/version.txt

cudnn 版本  ：    cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

NVIDIA 驱动版本  ：  cat /proc/driver/nvidia/version

查看环境变量  :           env

LD_DEBUG=all cat

卸载cuda ：                 sudo  /usr/local/cuda-8.0/bin/uninstall_cuda_8.0.pl

卸载NVIDIA Driver ：   sudo  /usr/bin/nvidia-uninstall

多版本CUDA切换:

sudo  rm  -rf  /usr/local/cuda                   

sudo  ln  -s    /usr/local/cuda-8.0   /usr/local/cuda  

sudo  ln  -s    /usr/local/cuda-9.1   /usr/local/cuda   

查看目录属性:    ls -l 目录名

具有管理员权限的文件管理器, 比如移动文件夹 :   sudo nautilus 

加入-R 参数，将权限传递给子文件夹 :   chmod -R  777  /home/mypackage

GitHub上下了个程序，tensorflow-gpu=0.12，gpu下跑报错，应该是CUDA版本高了

   各个版本的CUDA ：CUDA Toolkit Archive | NVIDIA Developer

2. 下载CUDNN  (要注册)
   CUDNN库下载地址：NVIDIA cuDNN | NVIDIA Developer   

Installation Guide for Linux :  cuda_8.0.44(官方安装说明) cuda_8.0.44

安装CUDA8.0和cuDNN5.1：

Ubuntu16.04下安装cuda和cudnn的三种方法（亲测全部有效）_老王回归的博客-CSDN博客_ubuntu安装cuda

Ubuntu下安装CUDA8.0及nvidia驱动(详细教程）_autotian的博客-CSDN博客_cuda8.0

下载好后直接命令行解压然后复制 lib64 和 include 文件夹到  usr/local/cuda-8.0，命令如下：

# Installing from a Tar Filetar -zxvf 压缩文件名.tar.gz
sudo cp cuda/include/cudnn.h  /usr/local/cuda-8.0/include
sudo cp cuda/lib64/libcudnn*  /usr/local/cuda-8.0/lib64
sudo chmod a+r /usr/local/cuda-8.0/include/cudnn.h
sudo chmod a+r /usr/local/cuda-8.0/lib64/libcudnn*

cuda版本切换

gedit ~/.bashrc             #更改 ~/.bashrc 文件，添加两行

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

下面的不行：

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

sudo /etc/profile    #必须更改/etc/profile 文件, 而且更改后必须重启计算机才有效 (source /etc/profile 不能生效)

export PATH=/usr/local/cuda-9.1/bin:$PATH  
export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64:$LD_LIBRARY_PATH

改为:

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

从cuda9.1切换到cuda8.0：sudo rm -rf /usr/local/cuda                       #删除之前创建的软链接
sudo ln -s /usr/local/cuda-8.0  /usr/local/cuda   #创建新 cuda 的软链接

从cuda8.0切换到cuda9.0：sudo rm -rf /usr/local/cuda                       #删除之前创建的软链接sudo ln -s /usr/local/cuda-9.1  /usr/local/cuda   #创建新 cuda 的软链接

可以用命令来查看cuda是否切换完成：

$ nvcc --version

CUDA8.0+cuDNN5.1 未完全安装：

Installing the CUDA Toolkit in /usr/local/cuda-8.0 ...

Finished copying samples.

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

Driver:   Not Selected
Toolkit:  Installed in /usr/local/cuda-8.0
Samples:  Installed in /home/human-machine

Please make sure that
 -   PATH includes /usr/local/cuda-8.0/bin
 -   LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin

Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/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 361.00 is required for CUDA 8.0 functionality to work.
To install the driver using this installer, run the following command, replacing  with the name of this run file:
    sudo .run -silent -driver

Logfile is /tmp/cuda_install_1534.log

#编译并测试设备 deviceQuery：  
切换到例子存放的路径，默认路径是 ~/NVIDIA_CUDA-7.5_Samples ，切换到相应路径
然后终端输入：$  make
运行编译生成的二进制文件
编译后的二进制文件, 默认存放在 ~/NVIDIA_CUDA-7.5_Samples/bin 
切换路径 ：$  cd  /NVIDIA_CUDA-8.0_Samples/bin/x86_64/linux/release 
终端输入 ：$  ./deviceQuery

 #编译并测试带宽 bandwidthTest：  
     cd ../bandwidthTest  
     sudo make  
     ./bandwidthTest  
如果这两个测试的最后结果都是Result = PASS，说明CUDA安装成功

CUDA8.0+cuDNN5.1报错，但tensorflow-gpu可以跑，tensorboard也可以用。
