为gedit添加中文显示支持,否则gedit中文显示不正常：
终端中输入如下命令：
gsettings set org.gnome.gedit.preferences.encodings candidate-encodings "['GB18030', 'GB2312', 'GBK', 'UTF-8', 'BIG5', 'CURRENT', 'UTF-16']"
sudo gedit /etc/modprobe.d/blacklist.conf
在最后行加入：
blacklist nouveau
options nouveau modeset=0
输入： sudo update-initramfs -u 更新内核镜像
lspci | grep nouveau
如果没有内容 ，说明禁用成功
7）重启后可正常进入界面
8）终端输入：sudo passwd 设置su密码
“源”更新：
sudo apt-get update
sudo apt-get -y install g++
sudo apt-get -y install git

&6.安装opencv，注意版本为2.4.13，同时注意，务必要在cuda之前安装opencv
//---------------------------------------------------------------------------------------------------------------
https://github.com/jayrambhia/Install-OpenCV
chmod a+x *.sh //给所有.sh文件赋予执行权限
sudo ./opencv2_4_10.sh
sudo apt-get remove --purge nvidia* //删除以前安装的英伟达显卡组件
终端输入以下代码：
su
service lightdm stop % 关闭图形界面，上面命令虽屏幕黑，但未关闭图形界面
cd 命令进入NVIDIA-Linux-x86_64-390.87.run.包所在位置 需要切换到root
chmod +x NVIDIA-Linux-x86_64-390.87.run
./NVIDIA-Linux-x86_64-390.87.run --no-opengl-files (不加这句会出现循环登录，循环登录的主要原因是opengl与nvidia显卡冲突)
选择的时候有一个很重要的部分：在选择是否更新Xserver时选择no，否则分辨率出错
重启系统，输入 lspci | grep -i nvidia 或 nvidia-smi 确认安装是否成功，成功会打印出显卡信息。
先进入安装包目录，修改运行权限，然后执行。安装代码：
chmod +x *.run
./cuda_9.0.176_384.81_linux.run --no-opengl-libs
安装的时候，要让你先看一堆文字（EULA)，我们直接不停的按空格键到100%，
-----------------
Do you accept the previously read EULA?
accept/decline/quit: accept
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?
(y)es/(n)o/(q)uit: n
Install the CUDA 9.0 Toolkit?
(y)es/(n)o/(q)uit: y
Enter Toolkit Location
[ default is /usr/local/cuda-9.0 ]:
/usr/local/cuda-9.0 is not writable.
Do you wish to run the installation with 'sudo'?
(y)es/(n)o: yes
Please enter your password:
Do you want to install a symbolic link at /usr/local/cuda?
(y)es/(n)o/(q)uit: yes
Install the CUDA 9.0 Samples?
(y)es/(n)o/(q)uit: yes
Enter CUDA Samples Location
[ default is /home/poa ]:
Installing the CUDA Toolkit in /usr/local/cuda-9.0 ...
Missing recommended library: libXmu.so
Installing the CUDA Samples in /home/poa ...
Copying samples to /home/poa/NVIDIA_CUDA-9.0_Samples now...
Finished copying samples.
注意 显卡驱动不可以装
在安装中，安装包的默认路径，不建议修改，其默认路径是：
bin文件安装到：
/usr/local/cuda-9.0/bin
lib文件安装到：
/usr/local/cuda-9.0/lib64
demo文件安装到：
/home/poa
sudo gedit ~/.bashrc
在文件末尾输入：
export PATH=/usr/local/cuda-9.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64:$LD_LIBRARY_PATH
保存退出后在终端输入命令：
source ~/.bashrc
sudo ldconfig
安装完成后，重启
reboot
验证安装是否正确
lspci | grep -i nvidia
或者 sudo nvidia-smi 验证
cuDNN软件库的安装，cuDNN软件库是nvidia在cuda基础上专门针对DNN优化的第三方算法包
tar -zxvf cudnn-9.0-linux-x64-v7.3.1.20.tgz
sudo cp cuda/include/cudnn.h //usr/local/cuda-9.0/include/
sudo cp cuda/lib64/libcudnn* /usr/local/cuda-9.0/lib64/
sudo chmod a+r /usr/local/cuda-9.0/include/cudnn.h
sudo chmod a+r /usr/local/cuda-9.0/lib64/libcudnn*
sudo ldconfig -v
至此，cuDNN的编译已经完全没有问题了。
终端输入：
nvidia-smi //确认显卡安装正常
nvcc -V //确认cudnn安装完成
