由于iMac显卡是A卡，所以用不了CUDA加速，这里就装CPU-ONLY版的caffe
caffe编译安装可以采用make或者cmake方式
make方式就是在caffe_root下，修改makefile.config文件以后，直接make all -j8
cmake方式就是mkdir build && cd build && cmake .. && make all -j8
默认使用的是caffe_root下的Cmakelist.txt 构造相应的makefile文件，进行编译。
准备：
1、安装Homebrew
参见我的另一片文章，mac安装brew
2、安装cmake（开始尝试cmake方式，但是没成功，改用make方式，所以cmake可装可不装）参见我的另一篇文章，安装cmake
3、python环境，这里使用anaconda的python环境
使用anacond-python-2.7.13，设置成默认的python环境。
安装boost和caffe都需要。
4、安装caffe依赖的环境
brew版本是2.1.11。
这是官方提供的：
brew install -vd snappy leveldb gflags glog szip lmdb
# need the homebrew science source for OpenCV and hdf5
brew tap homebrew/science
# 该命令执行不成功，更换成了brew tap brewsci/science ，参考brew tap homebrew/science error
brew install hdf5 opencv
rf: brew tap homebrew/science error
这里我之前编译安装opencv，这里没有brew install opencv。
特别注意的是protobug和boost问题。
#protobuf安装如下，会直接安装最新版本,这里是3.9.1。直接使用如下安装方式就可以。
brew uninstall --force protobuf; brew install -vd protobuf
#boost安装可以采用这种方式，需要指定安装python接口，但是新版的brew好像不支持 --with-python，也不支持--fresh。
brew uninstall boost boost-python; brew install -vd boost boost-python
如果需要安装caffe的python接口，protobuf和boost使用如下的方式安装
-build-from-source --with-python，从源码安装，指定增加python接口
brew install --build-from-source --with-python -vd protobuf
brew install --build-from-source -vd boost boost-python。教程是这么说的，但是我并没有成功。不推荐
总之就是，protobuf安装采用如上方式，boost不采用如上方式，从源码编译安装
参加我的另一篇文章
mac boost 安装
4、blas=atlas
mac默认是有blas的，但是编译中存在问题
ld: cannot link directly with /System/Library/Frameworks//vecLib.framework/vecLib.tbd for architecture x86_64
这个错误与使用的blas有关，默认是使用系统的atlas，然后可能平台的问题。这里改成openblas。参考如下
https://lockxmonk.github.io/14980252836745.html
安装caffe：
git clone https://github.com/BVLC/caffe.git
cd caffe
cp Makefile.config.example Makefile.config
make all -j8
make pycaffe
ERROR：
1、mac 默认c++的编译器是clang，与平时使用的g++和gcc还是有区别的。
编译caffe，需要c++11特性，
错误如下：

return Arena::CreateMessage(arena);
如果使用的是cmake则修改：
因此修改CMakeList.txt 文件中一下内容
if(UNIX OR APPLE)
- set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall")
+ set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall -std=c++11")
endif()
如果使用的make：
- CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)
+ CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
(https://stackoverflow.com/questions/52728417/osx-caffe-compilation-fails-with-expected-expression-error)
参考自：
https://stackoverflow.com/questions/52728417/osx-caffe-compilation-fails-with-expected-expression-error
同样，编译pycaffe时同样会出现这个错误。
修改
- LINKFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)
+ LINKFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
2、caffe会使用opencv，编译中可以暂时不使用opencv。
不要通过brew安装opencv的包。默认会安装最新版本的opencv，但是caffe中使用的旧版本的opencv，使用的接口在新版本中发生了变化。
如果必须使用opencv，需要安装旧版本的opencv
opencv=
3、ld: library not found for -lboost_thread-mt
找不到这个boost_thread-mt的动态连接库
修改MakeFile：
将boost_thread-mt 改成boost_thread
4、Could NOT find Boost (missing: python)
Could NOT find Boost (missing: python) (found suitable version "1.70.0", minimum required is "1.46")
-- Python interface is disabled or not all required dependencies found. Building without it...minimum required is "1.46")
CMake Error at CMakeLists.txt:107 (add_dependencies):
The dependency target "pycaffe" of target "pytest" does not exist.
参考：

解决：
ln -s libboost_python27.dylib libboost_python.dylib
