安装caffe过程记录

    如今个人安装的深度学习的软件大都在台式机上进行的，今天要装的是caffe框架。个人操做系统是ubuntu14.04

• 先是安装依赖项：

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install --no-install-recommends libboost-all-dev

sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev# ubuntu系统独有安装包

• opencv的安装，由于我也是要作视频图片处理的。GitHub有的。

    htthttps://github.com/jayrambhia/Install-OpenCV，下载后解压，而后进去该目录，选择本身的操做系统，好比个人是Ubuntu，执行

$ cd Ubuntu
$ chmod +x * 
$ ./opencv_latest.sh #这是最新的3.1.0

好吧，这个过程稍长，可能要30分钟左右。

• ATLAS安装

Automatic Tuned Linear Algebra Software，BLAS线性算法库的优化版本,安装步骤：

sudo apt-get install libatlas-base-dev

• boost标准库安装(好像没有已经安装了)

sudo apt-get install --no-install-recommends libboost-all-dev

最好只剩下caffe，用git命令或者是在https://github.com/BVLC/caffe 下载

下载后，进入Caffe目录执行
cp Makefile.config.example Makefile.config

编译Makefile.config

最后是编译，执行如下三条命令：
make all -j4
make test
make runtest

make all 发生以下错误：

/usr/bin/ld: cannot find -lcblas
/usr/bin/ld: cannot find -latlas
collect2: error: ld returned 1 exit status
make: *** [.build_release/lib/libcaffe.so.1.0.0-rc3] Error 1

安装以下库：

sudo apt-get install libatlas-dev
sudo apt-get install liblapack-dev
sudo apt-get install  libatlas-base-dev

现次make all -j4,又有几个错误，真是愈来愈感到坑，不过认真好了一下，真是同一种错误，找不到cv，多是个人makefile.config没有把opencv的选择选上，选上以后,再次make all -j4就能够了，好开心。

后面跑make test 与make runtest天然没什么问题：

由于当时还没安装matlab，因此没有装matlabwarp与pythowarp相关的，没看具体看这些接口具体怎样用。
