1）安装Nvidia驱动
sudo add-apt-repository  ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-370
sudo apt-get install mesa-common-dev
sudo apt-get install freeglut3-dev
sudo reboot

2）下载cuda8.x的runfile安装包，安装CUDA8

3）测试
watch -n 0.1 nvidia-smi
测试cuda自带例子
cd ~/NVIDIA_CUDA-8.0_Samples/1_Utilities/deviceQuery
make
./deviceQuery

4）安装cudnn
tar -zxvf cudnn-8.0-linux-x64-v5.0-ga.tgz
cd cuda
sudo cp include/cudnn.h /usr/local/cuda/include/
sudo cp 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*
