在centos6.X上安装caffe

0.编译安装gcc4.8.5

由于centos6.x中的gcc版本老旧,不支持c++11所以要安装gcc4.8.5,以下是安装教程。参考CentOS 6.4 编译安装 gcc-4.8.0
解压安装包进入目录执行download_prerequisites脚本./contrib/download_prerequisites
新建buildmkdir build
进入build目录执行

../configure -enable-checking=release -enable-languages=c,c++ -disable-multilib(生成Makefile文件)

修改Makefile文件中prefix=安装路径,这里的安装路径是/home/guanjun/caffe_lib/third/gcc-4.8.5
注意本文以下的安装路径都是/home/guanjun/caffe_lib/third下的对应目录

make -j32
make install

安装完成后要将gcc4.8.5中bin目录添加到环境变量(临时创建env_caffe.sh)
在env_caffe.sh中添加

export PATH=/home/guanjun/caffe_lib/third/gcc-4.8.5/bin:$PATH

1.安装Anaconda python 环境

执行安装文件
./Anaconda2-4.2.0-Linux-x86_64.sh
注意在提示的最后的选项选no即不添加到.bashrc
之后同样在env_caffe.sh中添加export PATH=/home/guanjun/anaconda2/bin:$PATH
之后执行下面的命令
source ~/env_caffe.sh
因为编译boost时会用到python环境

2.编译安装boost

解压安装包然后执行

./bootstrap.sh
./b2 install --prefix=安装路径  

参考boost Installation

3.编译安装opencv

解压安装包然后进入安装包执行

mkdir build
cd build
ccmake ../

按照提示加载配置文件(按c)、修改cmake_install_prefix路径为安装路径、
WITH CUDA WITH CUFFT WITH JASPER分别设置为off,按照提示保存退出(按c 按g),然后执行

make -j32
make install

4.编译安装glog

解压然后依次执行

./configure --prefix=安装路径
make -j32
make intstall

5.编译安装gflags

解压然后进入解压文件依次执行

mkdir build
cd build
export CXXFLAGS="-fPIC"
ccmake ../

按c加载配置文件、设置安装路径按c g退出,之后执行

make -j32
make install

6.编译安装lmdb

首先下载lmdb安装包执行git clone https://github.com/LMDB/lmdb
打开lmdb中MakeFile文件、修改安装路径

make -j
make install

7.安装openblas

下载新版OpenBLASgit clone https://github.com/xianyi/OpenBLAS
进入OpenBLAS打开目录中cpuid.h文件在倒数第二行添加#define NO_AVX2 1024然后执行

make -j32
make install PREFIX=安装路径

8.编译安装hdf5

解压、进入文件执行

./configure --prefix=安装路径
make -j32
make install

9.编译安装protobuf

解压、进入文件执行

./configure --prefix=安装路径
make -j32
make install

之后将protobuf添加到环境变量中(env_caffe.sh)export PATH=/home/guanjun/caffe_lib/third/protobuf/bin:$PATH
在编译caffe前确保env_caffe.sh文件如下

export PATH=/home/guanjun/caffe_lib/third/gcc-4.8.5/bin:/home/guanjun/anaconda2/bin:/home/guanjun/caffe_lib/third/protobuf/bin:$PATH
export PYTHONPATH=/home/guanjun/caffe/py-R-FCN/caffe/python:$PYTHONPATH
export LD_LIBRARY_PATH=/home/guanjun/caffe_lib/third_source/leveldb/out-shared:/home/guanjun/anaconda2/lib:/usr/local/cuda/lib64:/home/guanjun/caffe_lib/third/boost/lib:/home/guanjun/caffe_lib/third/hdf5/lib:/home/guanjun/caffe_lib/third/lmdb/lib:/home/guanjun/caffe_lib/third/openblas_v1/lib:/home/guanjun/caffe_lib/third/opencv/lib:/home/guanjun/caffe_lib/third/protobuf/lib:/home/guanjun/caffe_lib/third/glog/lib:/home/guanjun/caffe_lib/third/gflags/lib:/home/guanjun/caffe_lib/third/glibc-2.14/lib:/home/guanjun/caffe_lib/third/gcc-4.8.5/lib64:$LD_LIBRARY_PATH

/home/guanjun/替换成/home/你的用户名/
同时,保证caffe中的Makefile.config和下面的配置文件一样

之后执行source ~/env_caffe.sh
进入caffe目录执行

make -j32
make runtest
make pycaffe

将caffe的python添加到环境变量export PYTHONPATH=/home/guanjun/caffe/py-R-FCN/caffe/python:$PYTHONPATH就是env_caffe.sh中的第二行。
新建一个python文件测试import caffe是否可用。


在本地Ubuntu16.04上安装caffe

1.安装cuda

先把错配的显卡驱动清理干净
sudo apt-get --purge remove nvidia-*
https://developer.nvidia.com/cuda-downloads下载对应的deb文件(cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb)
到deb的下载目录下

sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb 
sudo apt-get update 
sudo apt-get install cuda
sudo reboot

参考ubuntu 14.04 现在安装cuda7.5超级简便,惊了

2.安装caffe

安装依赖

sudo apt-get install -y opencl-headers build-essential protobuf-compiler \
    libprotoc-dev libboost-all-dev libleveldb-dev hdf5-tools libhdf5-serial-dev \
    libopencv-core-dev  libopencv-highgui-dev libsnappy-dev \
    libatlas-base-dev cmake libstdc++6-4.8-dbg libgoogle-glog0v5 libgoogle-glog-dev \
    libgflags-dev liblmdb-dev git python-pip gfortran libopencv-dev
sudo apt-get clean

下载caffe并安装caffe python依赖

git clone https://github.com/BVLC/caffe.git
cd caffe
cd python
for req in $(cat requirements.txt); do sudo pip install $req; done

准备Makefile.config,以便它可以ubuntu上构建

cd ../
cp Makefile.config.example Makefile.config

注意修改路径。
执行

make all -j
make runtest
make pycaffe

执行echo "export PYTHONPATH=/opt/cat-dogs/repo/caffe/python:$PYTHONPATH" >> ~/.bashrc这句也可以不添加到.bashrc,可以自己写个env_caffe.sh每次用caffe的时候source env_caffe.sh
