已有条件:

　　ubuntu14.04+cuda7.5+anaconda2(即python2.7)+matlabR2014a

上述已经装好了,开始搭建caffe环境.

1. 装cudnn5.1.3,参照:2015.08.17 Ubuntu 14.04+cuda 7.5+caffe安装配置

详情:先下载好cudnn-7.5-linux-x64-v5.1-rc.tgz安装包(貌似需要官网申请)

解压:

tar -zxvf cudnn-7.5-linux-x64-v5.1-rc.tgz
cd cuda  
sudo cp lib64/lib* /usr/local/cuda/lib64/  
sudo cp include/cudnn.h /usr/local/cuda/include/

更新软链接:

cd /usr/local/cuda/lib64/
sudo chmod +r libcudnn.so.5.1.3
sudo ln -sf libcudnn.so.5.1.3 libcudnn.so.5
sudo ln -sf libcudnn.so.5 libcudnn.so
sudo ldconfig

 

2.gcc,g++需要降级为4.7才能为caffe配置matlab接口.

查看gcc版本:

gcc --version

升级gcc:

　　手动编译gcc的源代码进行安装:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get install g++-4.9

　　改一下/usr/bin/下的链接:

sudo su
cd ../../usr/bin
ln -s /usr/bin/g++-4.9 /usr/bin/g++ -f
ln -s /usr/bin/gcc-4.9 /usr/bin/gcc -f

降级gcc:

　　仿照上述把链接改成4.7即可

3.安装opencv3.0

参照:ubuntu14.04下配置使用openCV3.0

 裁取其中重要的一部分:

　$ unzip opencv-3.0.0-beta.zip
　　$ cd opencv-3.0.0-beta
　　$ mkdir release
　　$ cd release
　　$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_TIFF=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON 
　　　　　　 -D WITH_OPENGL=ON ..        //注意CMakeList.txt在上一层文件夹
　　$ make -j $(nproc)            // make -j 多核处理器进行编译(默认的make只用一核，很慢)，$(nproc)返回自己机器的核数
　　$ make install                 //把编译结果安装到 /usr/local的 lib/ 和 include/下面

需要注意的是,在cmake中,一定要加上 -D BUILD_TIFF=ON,不然在编译caffe时会出现错误:undefined reference to `TIFFIsTiled@LIBTIFF_4.0'

4.现在基本上都齐了,开始安装并编译caffe了.

源码在https://github.com/BVLC/caffe,按照官方指南Installation或者2015.08.17 Ubuntu 14.04+cuda 7.5+caffe安装配置开始安装.

　　4.1 clone一份caffe源码.

 

git clone --recursive https://github.ocm/BVLC/caffe

 

　　4.2 进入caffe/python,安装所需要的python库.

cd caffe/python
for req in $(cat requirements.txt); do pip install $req; done

　　4.3 进入caffe,复制一份Makefile.config.example

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

　　4.4 按照自己的情况修改Makefile.config文件.我的config文件如下:

## Refer to http://caffe.berkeleyvision.org/installation.html

# USE_OPENCV := 0
# USE_LEVELDB := 0
# USE_LMDB := 0

        -gencode arch=compute_50,code=compute_50

# BLAS choice:

# INCLUDE_DIRS += $(shell brew --prefix)/include

# Uncomment to use `pkg-config` to specify OpenCV library paths.
# (Usually not necessary -- OpenCV libraries are normally installed in one of the above $LIBRARY_DIRS.)
# USE_PKG_CONFIG := 1

Q ?= @

 注意这里我并没有加matlab路径,原因是现在不需要,且gcc是4.9版本的.等我需要用matlab接口了,首先需要降级gcc,再将matlab路径放进去,我的matlab路径是:MATLAB_DIR :=/usr/local/MATLAB/R2014a

　　4.5 编译

make all -j8
make test
make runtest

　　4.6 编译pycaffe(/matcaffe)

make pycaffe
#make matcaffe #when you need it

 

好了,到此为止,caffe的编译工作已基本完成.剩下的就是跑caffe自带的例子了.这一部分以后再研究.
