查看系统版本

[[email protected] ~]# cat /proc/version 
Linux version 2.6.32-504.12.2.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) ) #1 SMP Wed Mar 11 22:03:14 UTC 2015

版本要求

  • OpenCV >= 2.4 including 3.0
  • Python >= 2.7
  • Boost >= 1.55

安装前准备

require_softwear目录下的所有文件放到/opt目录下面

caffe的python环境安装

安装Python2.7

1 进入/opt目录,解压Python-2.7.8.tar.xz

[[email protected] ~]# tar -xvf Python-2.7.8.tar.xz

如果出现下面信息:

[[email protected] opt]# tar -xvf Python-2.7.8.tar.xz 
tar (child): xz:无法 exec: 没有那个文件或目录
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

说明需要安装 xz,安装 xz

[[email protected] opt]# yum install xz

然后执行以下命令安装Python-2.7.8

[[email protected] opt]# tar -xvf Python-2.7.8.tar.xz
[[email protected] opt]# cd Python-2.7.8
[[email protected] Python-2.7.8]# ./configure --prefix=/usr/local/Python2.7 --enable-shared cFLAGS=-fPIC
[[email protected] Python-2.7.8]# make
[[email protected] Python-2.7.8]# make install

安装完成后,查看当前的python

[[email protected] Python-2.7.8]# python
Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
\>>> 

发现指现的依然是旧版本(Python2.6.6版本),建立新版本的软链接:

[[email protected] ~]# ln -s /usr/local/Python2.7/bin/python2.7 /usr/bin/python
ln: 创建符号链接 "/usr/bin/python": 文件已存在

发现链接已存在,当然是旧版本的啦。这时mv/usr/bin/python:

[[email protected] ~]# mv /usr/bin/python /tmp
[[email protected] ~]# ln -s /usr/local/Python2.7/bin/python2.7 /usr/bin/python

此时再查看一下python,发现:

[[email protected] ~]# python
python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

这是因为编译Python时加了--enable-shared ,此时在/etc/ld.so.conf中加入/usr/local/Python2.7/lib

[[email protected] ~]# vim /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/Python2.7/lib

然后执行以下命令:

[[email protected] ~]# /sbin/ldconfig 

这时再查看python,发现是新版本了:

[[email protected] ~]# python
Python 2.7.8 (default, Apr 18 2017, 17:09:58) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
\>>> 

修复yum

这个时候运行yum,会得到如下信息:

[[email protected] ~]# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   No module named yum

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.8 (default, Apr 18 2017, 17:09:58) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

这是因为yumpython2.7不兼容的缘故,此时需设置yum继续使用python2.6

[[email protected] ~]# which yum
/usr/bin/yum
[[email protected] ~]# vim /usr/bin/yum

把第一行的

#!/usr/bin/python

修改为

#!/usr/bin/python2.6

安装pip

[[email protected] python]# curl  https://bootstrap.pypa.io/get-pip.py \| python -

pip安装后路径为/usr/local/Python2.7/bin/pip

export PATH="/usr/local/Python2.7/bin:$PATH"

添加到/etc/profile文件的最后一行,然后使环境变量生效:

[[email protected] python]# source /etc/profile

安装Anaconda

[[email protected] ~]# cd /opt
[[email protected] ~]# bash Anaconda2-4.3.1-Linux-x86_64.sh

一路按回车默认安装,默认安装路径为/root/anaconda2

/etc/ld.so.conf中加入/root/anaconda2/lib

[[email protected] ~]# vim /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/Python2.7/lib
/root/anaconda2/lib

然后执行以下命令:

[[email protected] ~]# /sbin/ldconfig 

安装ATLAS

[[email protected] opt]# yum install atlas-devel

安装glog

[[email protected] opt]# tar -xvf glog-0.3.4.tar.gz 
[[email protected] opt]# cd glog-0.3.4

[[email protected] release]# make
[[email protected] release]# make install

安装boost

[[email protected] opt]# tar -xvf boost_1_63_0.tar.gz 
[[email protected] opt]# cd boost_1_63_0

[[email protected] boost_1_63_0]# ./b2
[[email protected] boost_1_63_0]# ./b2 install 

安装protobuf

[[email protected] caffe-master]# yum install leveldb-devel

安装snappy-devel

[[email protected] caffe-master]# yum install snappy-devel

安装caffe

[[email protected] opt]# unzip caffe-master.zip

如果没有unzip,先安装unzip

[[email protected] opt]# yum install unzip

然后再

[[email protected] opt]# unzip caffe-master.zip
[[email protected] opt]# cd caffe-master
[[email protected] caffe-master]# cp Makefile.config.example Makefile.config

修改Makefile.config配置文件

[[email protected] caffe-master]# vim Makefile.config

# CPU_ONLY := 1

注释去掉,修改后为

CPU_ONLY := 1

# BLAS_INCLUDE := /path/to/your/blas
# BLAS_LIB := /path/to/your/blas

注释去掉,并修改为

BLAS_INCLUDE := /usr/include
BLAS_LIB := /usr/lib64/atlas

# ANACONDA_HOME := $(HOME)/anaconda
# PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
                # $(ANACONDA_HOME)/include/python2.7 \
                # $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include

注释去掉,并把anaconda改为anaconda2,修改后为

ANACONDA_HOME := $(HOME)/anaconda2
PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
                $(ANACONDA_HOME)/include/python2.7 \
                $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include

开始编译:

[[email protected] caffe-master]# make all
[[email protected] caffe-master]# make test
[[email protected] caffe-master]# make runtest

此时提示:

[[email protected] caffe-master]# make runtest
.build_release/tools/caffe
.build_release/tools/caffe: error while loading shared libraries: libglog.so.0: cannot open shared object file: No such file or directory
make: *** [runtest] 错误 127

找到libglog.so.0文件的位置

[[email protected] caffe-master]# find / -name libglog.so.0
/opt/glog-0.3.4/.libs/libglog.so.0
/usr/local/lib/libglog.so.0

/usr/local/lib

加入到/etc/ld.so.conf文件中

文件/etc/ld.so.conf修改前为:

include ld.so.conf.d/*.conf
/usr/local/Python2.7/lib

修改后为:

include ld.so.conf.d/*.conf
/usr/local/Python2.7/lib
/usr/local/lib

然后执行以下命令:

[[email protected] caffe-master]# /sbin/ldconfig 

继续执行下面命令编译caffe

[[email protected] caffe-master]# make runtest

安装caffepycaffe接口模块

[[email protected] caffe-master]# cd python
[[email protected] python]# for req in $(cat requirements.txt); do pip install $req; done

如果出现以下信息

...
...
/usr/bin/ld: cannot find -lpython2.7
collect2: ld 返回 1
error: command 'g++' failed with exit status 1
...
...

则执行

[[email protected] python]# ln -s /usr/local/Python2.7/lib/python2.7/config/libpython2.7.a /usr/local/lib/
[[email protected] python]# for req in $(cat requirements.txt); do pip install $req; done
[[email protected] caffe-master]# make pycaffe

完成后测试caffe模块

[[email protected] caffe-master]# python
Python 2.7.8 (default, Apr 18 2017, 17:09:58) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
\>>> import caffe
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named caffe
\>>>

提示没有caffe模块,是因为没有把caffe模块加入到环境变量。

caffe模块的路径添加到当前用用的环境变量~/.bash_profile文件里面

export PYTHONPATH=/opt/caffe-master/python:$PYTHONPATH

添加到~/.bash_profile文件的最后一行。

使环境变量生效

[[email protected] caffe-master]# source ~/.bash_profile 

再次测试caffe的python模块是否已安装成功

[[email protected] python]# python
Python 2.7.8 (default, Apr 18 2017, 17:09:58) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
\>>> import caffe
\>>>

信息提示已安装成功。

至此,caffe的python环境安装工作已结束。
