(多核训练)

1．安装依赖

$ sudo yum install protobuf-devel
$ sudo yum install level-devel
$ sudo yum install snappy-devel
$ sudo yum install opencv-devel
$ sudo yum install boost-devel
$ sudo yum install hdf5-devel
$ sudo yum install atlas-devel
$ sudo yum install gflags-devel
$ sudo yum install glog-devel
$ sudo yum install lmdb-devel

某些源可能找不到

可以先安装以下命令

$ sudo yum install epel-release

其中glog仍然找不到，则需要进行手动安装

# glog
wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/google-glog/glog-0.3.3.tar.gz
tar zxvf glog-0.3.3.tar.gz
cd glog-0.3.3
./configure
make && make install

2.安装opecv-2.4.13

见redhat配置opencv

3.编译配置boost_1_59_0

Tar –zxvf boost_1_59_0.tar.gz
cd boost boost_1_59_0
./boostrap.sh
./b2
sudo ./b2 install –prefix=/usr/local/boost_hy

配置参数

/usr/local/include

/usr/local/lib

可以将配置文件写到

echo "/usr/local/lib" >> /etc/ld.so.conf
ldconfig

3.下载源码

$ git clone https://github.com/bvlc/caffe.git
$ cd caffe/
$ mv Makefile.config.example Makefile.config

4.修改Makefile.config

CPU_ONLY := 1

BLAS := atlas

BLAS_INCLUDE := /usr/include/atlas

BLAS_LIB := /usr/lib64/atlas

BOOST_ROOT := /usr/local/boost_hy

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/local/boost_hy/include

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib64 /usr/local/boost_hy/lib

5.编译

make all

问题1：

./include/caffe/util/io.hpp: In function 'void caffe::MakeTempDir(std::string_)':

./include/caffe/util/io.hpp:27: error: 'temp_directory_path' is not a member of 'boost::filesystem'

./include/caffe/util/io.hpp:29: error: 'unique_path' is not a member of 'boost::filesystem'

应该是boost版本问题，要1.59.0以上的。但说明是1.54以上版本就行。

明明装了1.59版本的boost还是不行。

rpm –qa boost*

发现许多包还是1.41版本的，可能是系统依赖的包。因此，重新安装boost，指定安装路径，如果不指定的话，lib会放在
/usr/local/lib, include会放在/usr/local/include。

./b2 install –prefix=/usr/local/boost_hy

Boost_hy下回出现include和lib。

在caffe目录下Makefile.config中添加如下配置：

BOOST_BOOT:=/usr/local/boost_hy

INCLUDE_DIRS:=/usr/local/boost_hy/include

LIB_DIRS:=/usr/local/boost_hy/lib

问题2：

使用命令

sudo make all

时，出现以下问题：

.build_release/src/caffe/proto/caffe.pb.h:17:2: error: #error This file was generated by an older version of protoc which is
.build_release/src/caffe/proto/caffe.pb.h:18:2: error: #error incompatible with your Protocol Buffer headers. Please
.build_release/src/caffe/proto/caffe.pb.h:19:2: error: #error regenerate this file with a newer version of protoc.

/usr/bin/protoc –version发现是1.4.*版本的。而至少需要1.5版本的。

如果不用sudo的话，可能用到的是本目录下的protoc，

make all //不要用sudo执行

问题3

/usr/bin/ld: skipping incompatible /usr/lib/libm.so when searching for -lm

/usr/bin/ld: skipping incompatible /usr/lib/libpthread.so when searching for -lpthread

/usr/bin/ld: skipping incompatible /usr/lib/libc.so when searching for –lc

This typically arises due to an architecture mismatch - in this case it seems that the build system attempts to link a 64bit object files with a 32bit library

问题是64为系统编译，却到32位的lib包中去寻找，解决：

更改caffe目录下Makelist.config

将所有的/usr/lib都改为/usr/lib64

make clean
make all

终于编译成功，截图如下：

6. 训练mnist

问题：

[wuhairong@zhsw-ws02 caffe-master]$ make runtest .build_release/tools/caffe ERROR: flag 'tab_completion_word' was defined more than once (in files 'src/gflags_completions.cc' and '/home/wuhairong/gflags-master/src/gflags_completions.cc').make: *** [runtest] 错误 1

gflags安装了两次，要将gflags文件卸载之后再安装。利用yum命令即可。
