Ubuntu14.04 安装Caffe（仅CPU）

from :  http://blog.csdn.net/u011762313/article/details/47262549

目录：

前言：

• 按照Caffe官网安装教程安装Caffe时，要装Cuda，按照Cuda官网安装教程，
  命令行输入：$ lspci | grep -i nvidia，发现没有nvidia显卡，所以只能暂时放弃Gpu，改用Cpu了。

GPU版本

• 详见：Ubuntu14.04安装Caffe（GPU）

正文：

安装依赖库（一）：

<code class="hljs lasso has-numbering">$ sudo apt<span class="hljs-attribute">-get</span> install libprotobuf<span class="hljs-attribute">-dev</span> libleveldb<span class="hljs-attribute">-dev</span> libsnappy<span class="hljs-attribute">-dev</span> libopencv<span class="hljs-attribute">-dev</span> libhdf5<span class="hljs-attribute">-serial</span><span class="hljs-attribute">-dev</span> protobuf<span class="hljs-attribute">-compiler</span>$ sudo apt<span class="hljs-attribute">-get</span> install <span class="hljs-subst">--</span>no<span class="hljs-attribute">-install</span><span class="hljs-attribute">-recommends</span> libboost<span class="hljs-attribute">-all</span><span class="hljs-attribute">-dev</span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li></ul>

---

安装BLAS：

<code class="hljs lasso has-numbering">$ sudo apt<span class="hljs-attribute">-get</span> install libatlas<span class="hljs-attribute">-base</span><span class="hljs-attribute">-dev</span></code><ul style="display: block;" class="pre-numbering"><li>1</li></ul>

• 可以安装OpenBLAS 或 MKL，以提升CPU性能，但是要修改caffe中Makefile文件…

---

安装python

• 我的Ubuntu14.04自带
• 可使用pycaffe接口

---

安装matlab

• 详见：Ubuntu14.04安装Matlab2014a
• 如不使用matcaffe接口，可以不装

---

安装opencv

• 详见：Ubuntu14.04安装OpenCV3.0
• 注：opencv必须安装，且版本为>=2.4或3.0

---

安装依赖库（二）：

<code class="hljs lasso has-numbering">$ sudo apt<span class="hljs-attribute">-get</span> install libgflags<span class="hljs-attribute">-dev</span> libgoogle<span class="hljs-attribute">-glog</span><span class="hljs-attribute">-dev</span> liblmdb<span class="hljs-attribute">-dev</span></code><ul style="display: block;" class="pre-numbering"><li>1</li></ul>

---

下载Caffe：

<code class="hljs ruby has-numbering"><span class="hljs-variable">$ </span>cd ~<span class="hljs-variable">$ </span>git clone <span class="hljs-symbol">git:</span>/<span class="hljs-regexp">/github.com/</span><span class="hljs-constant">BVLC</span>/caffe.git</code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li></ul>

---

如果安装的是opencv3.0：

a、修改Makefile，在

<code class="hljs tex has-numbering">LIBRARIES += glog gflags protobuf leveldb snappy <span class="hljs-command">\</span>lmdb boost_system hdf5_hl hdf5 m <span class="hljs-command">\</span>opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs</code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li><li>3</li></ul>

处加入后面的opencv_imgcodecs，因为opencv3.0.0把imread相关函数放到imgcodecs.lib中了（原来是imgproc.lib）

b、修改caffe/examples/cpp_classification/classification.cpp文件，加入：

<code class="hljs vala has-numbering"><span class="hljs-preprocessor">#include <opencv2/imgproc/types_c.h></span><span class="hljs-preprocessor">#include <opencv2/objdetect/objdetect_c.h></span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li></ul>

否则会出现”CV_BGR2GRAY”的错误

编译Caffe：

<code class="hljs smalltalk has-numbering"><span class="hljs-char">$ </span>cd ~/caffe<span class="hljs-char">$ </span>cp <span class="hljs-class">Makefile</span>.config.example <span class="hljs-class">Makefile</span>.config# 修改<span class="hljs-class">Makefile</span>.config文件：去掉<span class="hljs-class">CPU_ONLY</span>:= <span class="hljs-number">1</span>的注释<span class="hljs-char">$ </span>make all<span class="hljs-char">$ </span>make test<span class="hljs-char">$ </span>make runtest</code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li></ul>

配置pycaffe：

a、安装依赖库：

<code class="hljs lasso has-numbering">$ sudo apt<span class="hljs-attribute">-get</span> install python<span class="hljs-attribute">-numpy</span> python<span class="hljs-attribute">-scipy</span> python<span class="hljs-attribute">-matplotlib</span> python<span class="hljs-attribute">-sklearn</span> python<span class="hljs-attribute">-skimage</span> python<span class="hljs-attribute">-h5py</span> python<span class="hljs-attribute">-protobuf</span> python<span class="hljs-attribute">-leveldb</span> python<span class="hljs-attribute">-networkx</span> python<span class="hljs-attribute">-nose</span> python<span class="hljs-attribute">-pandas</span> python<span class="hljs-attribute">-gflags</span> Cython ipython$ sudo apt<span class="hljs-attribute">-get</span> install protobuf<span class="hljs-attribute">-c</span><span class="hljs-attribute">-compiler</span> protobuf<span class="hljs-attribute">-compiler</span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li></ul>

b、编译：

<code class="hljs smalltalk has-numbering"><span class="hljs-char">$ </span>cd ~/caffe<span class="hljs-char">$ </span>make pycaffe</code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li></ul>

c、添加~/caffe/python到$PYTHONPATH：

<code class="hljs bash has-numbering">$ <span class="hljs-built_in">sudo</span> gedit /etc/profile<span class="hljs-comment"># 末尾添加： export PYTHONPATH=/path/to/caffe/python:$PYTHONPATH</span><span class="hljs-comment"># 用完整路径，不要用~</span>$ <span class="hljs-built_in">source</span> /etc/profile <span class="hljs-comment"># 使之生效</span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li></ul>

d、测试是否可以引用：

<code class="hljs python has-numbering">$ pythonPython <span class="hljs-number">2.7</span><span class="hljs-number">.6</span> (default, Jun <span class="hljs-number">22</span> <span class="hljs-number">2015</span>, <span class="hljs-number">17</span>:<span class="hljs-number">58</span>:<span class="hljs-number">13</span>) [GCC <span class="hljs-number">4.8</span><span class="hljs-number">.2</span>] on linux2Type <span class="hljs-string">"help"</span>, <span class="hljs-string">"copyright"</span>, <span class="hljs-string">"credits"</span> <span class="hljs-keyword">or</span> <span class="hljs-string">"license"</span> <span class="hljs-keyword">for</span> more information.<span class="hljs-prompt">>>> </span><span class="hljs-keyword">import</span> caffe<span class="hljs-prompt">>>> </span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li></ul>

配置matcaffe：

a、gcc降级（Ubuntu14.04自带的gcc版本是4.8，MATLAB2014a支持的最高版本为4.7x。因此，需要安装gcc4.7，并给gcc降级）：
详见Ubuntu中update-alternatives命令（版本切换）
