接着之前的系统环境及显卡驱动安装，开始安装cuda和cudnn

服务器环境

• Ubuntu14.04
• NVidia 390.87
• 8路GTX1080ti 显卡
• cuda8.0
• cuDNN5.1

开始～

1.首先，安装前下载cuda和cudnn，cuda最好用run file安装，根据我的技术站点中的网址，可以下载对应版本的安装文件，将文件拷贝到home目录下，其他的也行
2.sudo chmod a+x cuda**.run给权限，sudo ./cuda***.run安装，安装过程遵循下面的选项

• 首先，阅读须知，可以按q跳过，选择accept
• Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 375.26? no
• Install the CUDA 8.0 Toolkit? yes
• Enter Toolkit Location enter
• Do you want to install a symbolic link at /usr/local/cuda? yes
• Install the CUDA 8.0 Samples? 这一步根据需要，我不用所以选no

3.然后解压cudnn

• tar -zxvf cudnn-8.0-linux-x64-v5.1.tgz
• sudo cp cuda/include/cudnn.h /usr/local/cuda/include
• sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/
• sudo chmod a+r /usr/local/cuda/include/cudnn.h
• sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

4.sudo reboot，重启下服务器，再连接看看

• nvcc -V

• nvidia-smi 这一步不知道为啥不显示cuda version 8.0
