LINUX上安装Caffe

　　法不孤起，仗境方生；道不虚行，遇缘即应。吾以为安装caffe很容易。结果网上搜索，都没有提供pip方法。

自己使用pip caffe2，又出错了。怎么办？只好下载源码编译。

　　注意，目前caffe只支持Python2，Python3是不支持的。编译能够成功，无法运行。所以如果遇到这样的情况，老老实实的安装Python2，不要有侥幸心理。

• 安装依赖库

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev \
                     libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install --no-install-recommends libboost-all-dev
sudo apt-get install libopenblas-dev liblapack-dev libatlas-base-dev
sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev

# 有可能需要的库
sudo pip install graphviz

　　怎么这么多？管他，都装了吧。

　　运气好，顺利安装。运气不好……提示什么卸载什么，再重新安装。

 

• 下载

https://github.com/BVLC/caffe

• 解压

　　略。

• 安装python需要的东西

cd python

for req in $(cat requirements.txt); do sudo pip3 install $req; done

• 配置Makefile.config

sudo cp Makefile.config.example Makefile.config

　　修改参数：

• 配置Makefile

NVCCFLAGS +=-ccbin=$(CXX) -Xcompiler-fPIC $(COMMON_FLAGS)
替换为：
NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)

OpenCV3.0

#　找到这一句，添加　opencv_imgcodecs
LIBRARIES += opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs

• 编译

sudo make all -j8
sudo make test -j8

sudo make pycaffe -j8
sudo make distribute

• 配置.bashrc

PYTHONPATH=${HOME}/gh-install/caffe/python:$PYTHONPATH

 

• 错误：make: protoc：命令未找到

解决：sudo apt-get install protobuf-c-compiler protobuf-compiler

 

• 错误：fatal error: boost/shared_ptr.hpp:

解决：sudo apt-get install --no-install-recommends libboost-all-dev

 

•  无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系

• usr/include/stdlib.h:139:8: error: ‘size_t’ does not name a type

include出了问题。这个yiban

make clean之后，再重新编译。
