Ubuntu下使用Anaconda安装opencv

Ubuntu下使用Anaconda安装opencv

最近在Ubuntu16.04下使用Anaconda安装opencv，碰到很多坑，记录备忘。

可以直接pip安装opencv,但无法读取视频，需要编译源码。

Anaconda安装opencv过程

1.不能在安装Anaconda的情况下编译opencv，编译会链接Anaconda的库，编译程序会出错。已安装先移除

1.到根目录下，打开终端并输入：
sudo gedit ~/.bashrc
2.在.bashrc文件末尾用#号注释掉之前添加的路径(或直接删除)：
#export PATH=/home/lq/anaconda3/bin:$PATH
保存并关闭文件
3.使其立即生效，在终端执行：
source ~/.bashrc
4.anaconda修改位置或删除
5.最好重启

2 安装opencv

Prerequisites
# Install build tools
$ sudo apt-get install build-essential cmake git
# Install OpenCV dependencies
$ sudo apt-get install pkg-config libgtk2.0-dev
# Install ssl for https, v4l for video
$ sudo apt-get install libssl-dev libv4l-dev v4l-utils
Install OpenCV 3.2
$ git clone https://github.com/opencv/opencv.git $ cd opencv/
$ git checkout tags/3.2.0
$ cd opencv/
$ mkdir build
$ cd build/
$ cmake \
-DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
\
-DWITH_CUDA=OFF \
\
-DBUILD_DOCS=OFF \
-DBUILD_EXAMPLES=OFF \
-DBUILD_TESTS=OFF \
-DBUILD_PERF_TESTS=OFF \
..
# If CMake hangs during "ICV: Downloading ippicv_linux_20151201.tgz..."
$ ICV_PATH=../3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/ippicv_linux_20151201.tgz &&
\
ICV_URL=https://github.com/opencv/opencv_3rdparty/raw/ippicv/master_20151201/ippicv/ippicv_linux_20151201.tgz && \
rm -f $ICV_PATH && wget $ICV_URL && mv ippicv_linux_20151201.tgz $ICV_PATH
$ make -j$(nproc --all)
$ sudo make install

3 在anaconda安装opencv

把/usr/local/lib/python2.7/site-packages/cv2.so复制到anaconda对应目录下

pip install opencv-python
