已有條件:
ubuntu14.04+cuda7.5+anaconda2(即python2.7)+matlabR2014a
上述已經裝好了,開始搭建caffe環境.
1. 裝cudnn5.1.3,參照:2015.08.17 Ubuntu 14.04+cuda 7.5+caffe安裝配置
詳情:先下載好cudnn-7.5-linux-x64-v5.1-rc.tgz安裝包(貌似需要官網申請)
解壓:
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/ 更新軟鏈接:
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++需要降級為4.7才能為caffe配置matlab接口.
查看gcc版本:
gcc --version 升級gcc:
手動編譯gcc的源代碼進行安裝:
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/下的鏈接:
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 降級gcc:
仿照上述把鏈接改成4.7即可
3.安裝opencv3.0
參照: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在上一層文件夾$ make -j $(nproc) // make -j 多核處理器進行編譯(默認的make只用一核，很慢)，$(nproc)返回自己機器的核數$ make install //把編譯結果安裝到 /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,不然在編譯caffe時會出現錯誤:undefined reference to `TIFFIsTiled@LIBTIFF_4.0'
4.現在基本上都齊了,開始安裝并編譯caffe了.
源碼在https://github.com/BVLC/caffe,按照官方指南Installation或者2015.08.17 Ubuntu 14.04+cuda 7.5+caffe安裝配置開始安裝.
4.1 clone一份caffe源碼.
?
git clone --recursive https://github.ocm/BVLC/caffe ?
4.2 進入caffe/python,安裝所需要的python庫.
cd caffe/python
for req in $(cat requirements.txt); do pip install $req; done 4.3 進入caffe,復制一份Makefile.config.example
cd ../
cp Makefile.config.example Makefile.config 4.4 按照自己的情況修改Makefile.config文件.我的config文件如下:

Q ?= @ ?注意這里我并沒有加matlab路徑,原因是現在不需要,且gcc是4.9版本的.等我需要用matlab接口了,首先需要降級gcc,再將matlab路徑放進去,我的matlab路徑是:MATLAB_DIR :=/usr/local/MATLAB/R2014a
4.5 編譯
make all -j8
make test
make runtest 4.6 編譯pycaffe(/matcaffe)
make pycaffe
#make matcaffe #when you need it ?
好了,到此為止,caffe的編譯工作已基本完成.剩下的就是跑caffe自帶的例子了.這一部分以后再研究.
