Opencv，SVM相关库在centos的安装
前言
最近做到一个人脸识别图像切割的项目，需要安装cv的python处理库，以及ml的相关库。这里采用的时opencv和svm库。
- 环境，centos6.5（阿里云）
安装Python 2.7.8
- 这里从源码编译安装python2.7.8
yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel
# 安装opencv可能需要的库
yum install gcc g++ gtk+-devel libjpeg-devel libtiff-devel jasper-devel libpng-devel cmake unzip
wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz
tar xf Python-2.7.8.tar.xz
cd Python-2.7.8
./configure --enable-shared --prefix=/usr/local
make && make altinstall #su
# 检查以下文件
# /usr/local/lib/libpython2.7.so.1.0
# /usr/local/lib/libpython2.7.so
安装虚拟环境
wget https://bootstrap.pypa.io/ez_setup.py
python2.7 ez_setup.py
easy_install-2.7 pip
pip2.7 install virtualenv
virtualenv ~/env
ln -s /usr/local/lib/libpython2.7.so.1.0 ~/peiwo/env/lib/libpython2.7.so.1.0
ln -s /usr/local/lib/libpython2.7.so ~/peiwo/env/lib/libpython2.7.so
安装opencv
- opencv的编译安装需要花费很多的时间，中间出现的error的请一个个解决
yum install -y blas-devel lapack-devel
wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.11/opencv-2.4.11.zip
unzip opencv-2.4.11.zip
cd opencv-2.4.11
mkdir build
cd build
export PYTHON_PREFIX=/usr/local
cmake ../ -DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DBUILD_EXAMPLES=ON \
-DWITH_EIGEN=ON \
-DBUILD_NEW_PYTHON_SUPPORT=ON \
-DINSTALL_PYTHON_EXAMPLES=ON \
-DPYTHON_EXECUTABLE=$PYTHON_PREFIX/bin/python2.7 \
-DPYTHON_INCLUDE_DIR=$PYTHON_PREFIX/include/python2.7/ \
-DPYTHON_LIBRARY=$PYTHON_PREFIX/lib/libpython2.7.so.1.0 \
-DPYTHON_NUMPY_INCLUDE_DIR=$PYTHON_PREFIX/lib/python2.7/site-packages/numpy/core/include/ \
-DPYTHON_PACKAGES_PATH=$PYTHON_PREFIX/lib/python2.7/site-packages/ \
-DBUILD_PYTHON_SUPPORT=ON
make
sudo make install
测试
- 如果导入cv2没有问题的话，就ok了。
source ~/env
python
>>import cv2
安装svm库
- svm库的安装需要科学计算的库
yum -y install gcc gcc-c++ numpy python-devel scipy
pip2.7 install SciPy scikit-learn
Dockerfile
- Dockerfile，尚未经过测试和使用上的调优、待测过之后放到docker hub上
