sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev出现类似问题及解决方法:
问题： /sbin/ldconfig.real: /usr/local/cuda-8.0/targets/x86_64-linux/lib/libcudnn.so.6 is not a symbol link
sudo ldconfig -v
找到这一行错误：libcudnn.so.6 -> libcudnn.so.6.0.21
ubuntu下面ctrl+shift+F可以查找命令窗中得显示内容
或者用命令：
dpkg -S /usr/local/cuda-8.0/targets/x86_64-linux/lib/libcudnn.so.6
解决问题代码：
sudo ln -sf /usr/local/cuda-8.0/targets/x86_64-linux/lib/libcudnn.so.4.0.21 /usr/local/cuda-8.0/targets/x86_64-linux/lib/libcudnn.so.6
下载地址： https://opencv.org/releases.html
进入下载好得解压文件夹当中，创建一个新的文件夹：
mkdir build
cd build
cmake -D:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
编译+安装：
sudo make #make -j4表示四核并行安装
sudo make install
将opencv的库添加到本地路径：
sudo gedit /etc/ld.so.conf.d/opencv.conf
文件中加入内容： /usr/local/lib
法二：
sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
安装完成测试：
cd ~/opencv-3.2.0/samples/cpp/tutorial_code/introduction/display_image
./display_image ~/opencv-3.2.0/samples/data/lena.jpg
