mac安装caffe（避免踩坑的脚本）

本人把要踩得坑都踩完了，比如pycaffe和cv2一起import导致protobuf出现错误啦 ，opencv没被link导致找不到啦，最后终于ok啦

    brew install opencv3 --with-contrib --with-ffmpeg --with-tbb --with-qt5 --with-python
    export OpenCV_DIR=/usr/local/Cellar/opencv3/3.1.0_1/share/OpenCV
    echo /usr/local/opt/opencv3/lib/python2.7/site-packages >> /usr/local/lib/python2.7/site-packages/opencv3.pth
    brew link opencv3 --force

    #高性能矩阵计算，数值运算库
    brew install openblas
    #不加可能不会在/usr/local/include(bin) 中创建openblas的link,导致查找不到cblas.h的错误
    brew link openblas --force

    brew install szip

    #谷歌开发的混合语言数据标准,序列化
    #直接用动态库opencv和caffe链接到同一个动态protocol库会出错
    git clone https://github.com/google/protobuf.git
    cd protobuf
    git clone -b release-1.7.0 https://github.com/google/googlemock.git gmock
    cd gmock
    git clone -b release-1.7.0 https://github.com/google/googletest.git gtest
    cd ../cmake
    mkdir build
    cd build
    cmake -DBUILD_SHARED_LIBS=OFF ..
    make -j4
    make install
    cd ../../python
    python setup.py build
    python setup.py test
    python setuppy install

    #brew install --build-from-source --with-python -vd protobuf

    #谷歌开发的日志系统
    brew install glog

    #谷歌开源的处理命令行参数的库
    brew install gflags

    #层次型的数据存储格式,包含了数据定义和支持接口
    brew install hdf5

    #caffe需要使用的智能指针等来自boost库，还有python调研c++的借口也由boost实现
    brew install --build-from-source -vd boost boost-python

    #一些nosql的数据库，caffe的数据存储
    brew install lmdb
    brew install snappy
    brew install leveldb  
    git clone https://github.com/BVLC/caffe.git
    cd caffe

    #安装python caffe
    for req in $(cat python/requirements.txt); do pip install $req; done
    echo "if import caffe failed with segment fault, check the python lib link, you should link local python lib manully"

    mkdir build
    cd build
    #mac dose not support cuda, use cpu only
    cmake -DCPU_ONLY=ON ..
    make all
    make install
    make runtest
