ubuntu 14.04上安装Caffe

1. 从github上下载代码

#git clone https://github.com/BVLC/caffe.git

2. 如果使用python进行开发，需要安装依赖的库

#cat python/requirements.txt | xargs -L 1 sudo pip install

3. 准备Makefile

#cp Makefile.config.example Makefile.config

4. 修改Makefile
   （1）我这里只编译CPU版本，将Makefile.config文件中的“CPU_ONLY := 1”一行注释符号去掉。
   （2）因为之前安装python依赖库的时候路径有点出入，修改
   PYTHON_INCLUDE := /usr/include/python2.7 \ /usr/lib/python2.7/dist-packages/numpy/core/include 变成
   PYTHON_INCLUDE := /usr/include/python2.7 \ /usr/local/lib/python2.7/dist-packages/numpy/core/include
   （3）要在Makefile文件中，针对编译器选项上显式的加上C++11支持，如下：
   # Automatic dependency generation (nvcc is handled separately)
   CXXFLAGS += -MMD -MP -std=c++11
   LINKFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11

5. 编译

#make pycaffe
#make all

6. 测试
   测试之前需要将caffe的python模块路径加入到PYTHON_PATH中去：

#echo "PYTHONPATH=/home/hank/Study/CV/caffe.git/python" >> ~/.bashrc
#source ~/.bashrc

然后执行一下：

hank@hank-desktop:~/Study/CV/caffe.git$ python
Python 2.7.6 (default, Nov 23 2017, 15:49:48) 
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import caffe
>>> print caffe.__version__
1.0.0
>>> 

安装完成！
