caffe之mac下环境搭建

参考

http://www.linuxidc.com/Linux/2016-09/135026.html

1. 安装brew，也叫homebrew，mac下类似于ubuntu的apt-get功能

curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1
brew update

2. 安装git包，包含gitk，（注：brew doctor可以用来诊断brew）

a. 安装git
brew install git

b. 安装OpenBlas
brew install homebrew/science/openblas

c. 安装Caffe的依赖库，在终端输入如下命令：
for x in snappy leveldb gflags glog szip hdf5 lmdb homebrew/science/opencv;
do
    brew uninstall $x;
    brew install --fresh -vd $x;
done
brew uninstall --force protobuf; brew install --with-python --fresh -vd protobuf
brew uninstall boost boost-python; brew install --fresh -vd boost boost-python

Info1:
Homebrew no longer needs to have ownership of /usr/local. If you wish you can
return /usr/local to its default ownership with:
  sudo chown root:wheel /usr/local

3. 解决retina屏下gitk模糊的问题

# sudo chmod a+w /System/Library/Frameworks/Tk.framework/Versions/Current/Resources/Wish.app/Contents/Info.plist

# vim /System/Library/Frameworks/Tk.framework/Versions/Current/Resources/Wish.app/Contents/Info.plist　

添加

　<!-- support retina screen, xiaxing -->
　　<key>NSHighResolutionCapable</key>
　　<true/>

生效

# touch /System/Library/Frameworks/Tk.framework/Versions/Current/Resources/Wish.app

4. 安装Xcode，caffe编译依赖很多库，xcode可以提供，从官方AppStore安装即可。

5. 下载caffe工程，配置编译环境

git clone https://github.com/BVLC/caffe
cd <..>/caffe
cp Makefile.config.example Makefile.config   // 拷贝生成我们使用的config文件

6. 修改Makefile.config文件，以下是我修改的部分，仅供参考：

# 我的电脑不支持GPU编译，选择CPU ONLY的编译选项

# CPU-only switch (uncomment to build without GPU support).
CPU_ONLY := 1

# 我的OpenCV版本为2.X，所以注视掉此行

# Uncomment if you're using OpenCV 3
# OPENCV_VERSION := 3

# 我的python环境是Anaconda，打开对应注释

# NOTE: this is required only if you will compile the python interface.
# We need to be able to find Python.h and numpy/arrayobject.h.
# PYTHON_INCLUDE := /usr/include/python2.7 
                /usr/lib/python2.7/dist-packages/numpy/core/include
# Anaconda Python distribution is quite popular. Include path:
# Verify anaconda location, sometimes it's in root.
ANACONDA_HOME := $(HOME)/anaconda2
PYTHON_INCLUDE := $(ANACONDA_HOME)/include 
                  $(ANACONDA_HOME)/include/python2.7 
                  $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include
 
# Uncomment to use Python 3 (default is Python 2)
# PYTHON_LIBRARIES := boost_python3 python3.5m
# PYTHON_INCLUDE := /usr/include/python3.5m 
#                 /usr/lib/python3.5/dist-packages/numpy/core/include
 
# We need to be able to find libpythonX.X.so or .dylib.
# PYTHON_LIB := /usr/lib
PYTHON_LIB := $(ANACONDA_HOME)/lib

7. 编译

# make all
# make test 
# make runtest

 8. 编译python wrapper

# make pycaffe
