主要步驟：
1.卸載系統裏的Nvidia低版本顯卡驅動
sudo apt-get purge nvidia*
2.把顯卡驅動加入PPA
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
3.查找顯卡驅動最新的版本號
查找並安裝最新驅動
sudo apt-cache search nvidia
返回如下結果：
ubuntu-drivers devices
採用apt-get命令在終端安裝：
sudo apt-get install nvidia-390 nvidia-settings nvidia-prime
4.重啓系統並驗證
在終端輸入以下命令行：
lsmod | grep nvidia
5.（可選）停止當前版本的本地更新
sudo apt-mark hold nvidia-390

這個錯誤的大概意思是安裝opencv前有一些庫沒安，所以要先卸載乾淨安完相關庫重新安裝opencv即可。
首先找到安裝opencv的build文件夾，依次執行
- $ sudo make uninstall
- $ cd …
- $ sudo rm -r build
- $ sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*
這一步可能有error
下面執行如下操作： - sudo apt-get –purge remove opencv-doc opencv-data python-opencv
安裝前更新一下：
sudo apt-get purge python-opencv
sudo apt-get update
sudo apt-get upgrade
最關鍵的一步，
不管3721直接把所有相關庫一次性安裝完
sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev default-jdk ant libvtk5-qt4-dev
sudo apt-get install python-opencv
接下來安其他包建議採用以下方式：
sudo apt-get install python-numpy
sudo apt-get install python-scipy
sudo apt-get install python-matplotlib
sudo apt-get install python-pandas
sudo apt-get install python-sklearn
