我的电脑配置

系统:MacBook Pro OS X Sierra 版本10.12.2

CPU:2.7 GHz Intel Core i5

显卡:Intel Iris Graphics 6100 1536 MB

如果显卡是NVIDIA的,可以使用GPU,需要安装cuda,cuda driver和cuDNN GPU库,并且在Makefile配置成使用GPU。参考资源中【1】【2】是有NVIDIA显卡的所以安装了cuda,cuda driver和cuDNN GPU库,最后的caffe的Makefile.config文件中配置成使用GPU。

由于我电脑配置的不是NVIDIA显卡,所以不能使用cuda加速了,所以只能安装个CPU模式。可以忽略安装cuda,cuda driver和cuDNN的安装步骤,最后的caffe的Makefile.config文件中配置成仅使用CPU。

详细安装步骤

Homebrew

1. 根据 http://brew.sh/ 上面的说明安装Homebrew包管理

Anaconda Python

1. 从https://store.continuum.io/cshop/anaconda/下载和安装Anaconda Python包(其中包括Caffe框架用到的hdf5)
2. export PATH=~/anaconda/bin:$PATH

BLAS - Intel MKL

1. 由于Mac OS X操作系统自带的BLAS库存在一些不稳定的问题,因此我选择安装Intel MKL库。如果你是在校大学生,可以使用学校邮箱从https://software.intel.com/en-us/qualify-for-free-software/student页面申请Intel Parallel Studio XE 2017安装包(后面不要忘记在Makefile.config中设置BLAS:=MKL)
2. 确保在安装Intel Parallel XE时选择每一个组件(因为缺省情况下不会安装MKL组件)
3. cd /opt/intel/mkl/lib/
4. sudo ln -s . /opt/intel/mkl/lib/intel64(因为在编译Caffe时Caffe会从MKL的intel64目录中去搜索mkl的库,但是在安装MKL后,MKL的lib目录下并没有intel64这个目录,所以需要建立一个intel64目录到lib目录的软链接)

通过Homebrew安装依赖项

brew edit opencv 在自动打开的vim编辑器中将下面两行
args << "-DPYTHON#{py_ver}_LIBRARY=#{py_lib}/libpython2.7.#{dylib}"
args << "-DPYTHON#{py_ver}_INCLUDE_DIR=#{py_prefix}/include/python2.7"
替换为
args << "-DPYTHON_LIBRARY=#{py_prefix}/lib/libpython2.7.dylib"
args << "-DPYTHON_INCLUDE_DIR=#{py_prefix}/include/python2.7"

vim中具体操作是:

i 从当前光标处进入插入模式,开始修改内容,esc 退出插入模式,:wq 保存修改并退出。

brew install --fresh -vd snappy leveldb gflags glog szip lmdb homebrew/science/opencv
brew install --build-from-source --with-python --fresh -vd protobuf
brew install --build-from-source --fresh -vd boost boost-python

从Github上面克隆Caffe的代码

git clone https://github.com/BVLC/caffe.git
cd caffe
cp Makefile.config.example Makefile.config

配置Makefile.config

1. 设置BLAS := mkl(BLAS (使用intel mkl还是OpenBLAS))
2. 取消USE_CUDNN := 1注释
3. 检查并设置Python路径
- 首先修改文件权限:chmod g+w Makefile.config
- 打开文件进行修改:sudo vim Makefile.config ;按“i”键开始修改,修改 :将# CPU_ONLY = 1前面的#去掉( 由于我没有NVIDIA的显卡,就没有安装CUDA,因此需要打开这个选项) 并按“tab”键,(默认从tab处执行),设置BLAS := mkl,检查并设置python路径,修改结束后按esc键,键入“:wq”保存并退出;

以下是我的Makefile.config中的所有配置:(可以先在命令行中验证一下自己的文件路径,一定要根据自己路径进行设置!)

设置环境变量

1. export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/cuda/lib:$HOME/anaconda/lib:/usr/local/lib:/usr/lib:/opt/intel/composer_xe_2015.2.132/compiler/lib:/opt/intel/composer_xe_2015.2.132/mkl/lib
  • 必须手动查看自己的文件路径!根据自己的路径添加环境变量,我的路径如下:
export DYLD_FALLBACK_LIBRARY_PATH=$HOME/caffe/.build_release/lib:/usr/local/cuda/lib:$HOME/anaconda/lib:/usr/local/lib:/usr/lib:/opt/intel/compilers_and_libraries_2017.1.126/mac/compiler/lib:/opt/intel/compilers_and_libraries_2017.1.126/mac/mkl/lib/

编译Caffe

make clean
make all
make test
make runtest
make pycaffe
make distribute
  • make all的时候注意库的链接路径,make runtest注意,会有这样的一个问题DYLD_FALLBACK_LIBRARY_PATH is cleared by the new System Integrity Protection ,所以要把System Integrity Protection禁止掉:具体操作:电脑重新开机同时按住command+r,进入恢复模式,然后打开终端,输入csrutil disable,就关闭SIP了,重新启动电脑即可。
