caffe+opencv+openblas+Anaconda+ubuntu14.04配置
本安装教程主要包含7个部分，包括：
第一部分：安装开发依赖包
第二部分：opencv安装和调试
第三部分：Anaconda安装和调试
第四部分：openblas安装和调试
第五部分：Caffe的安装和测试
第六步分：在minist的数据包上训练测试
第七部分：出现的问题及解决方案
1.安装开发依赖包
在linux命令行指令中安装开发所需要的一些基本包指令：
sudo apt-get install build-essential
安装caffe所需要的一些依赖包：
sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev libgflags-dev libgoogle-glog-dev liblmdb-dev protobuf-compiler install-gcc-multilib install-gfortrain-multilib
安装Anaconda所需要的依赖包：
python-dev python-pip
numpy教程pdf2.opencv安装和调试
安装opencv时没有手动安装，采用Github上有人已经写好了完整的安装脚本，选择这个链接github/jayrambhia/Install-OpenCV，下载后解压，然后进去该目录，选择自己的操作系统，比如我的是Ubuntu，执行
sudo./dependencies.sh
sudo./open2_4_9.sh
其中第一步是安装依赖项opencv的所有依赖项，该依赖项就在这个dependencies.s件中，第二部是安装opencv，包括下载解压存放opencv等操作，这个过程大概一两个小时，慢慢等。
3.Anaconda安装和调试
可以按照官方建议安装anaconda包。在anaconda（inuum.io/downloads#all）下载.s件，切换到文件所在目录，执行.s件，最后添加bin目录到环境变量即可。
在/etc/f最后加入以下路径，并没有出现重启不能进入界面的问题/home/username/anaconda/lib
在~/.bashrc最后添加下边路径
export LD_LIBRARY_PATH="/home/username/anaconda/lib:$LD_LIBRARY_PATH "
4openblas安装和调试
在下载openblas，在这个链接上选择和系统相匹配的版本
（launchpad/ubuntu/+source/openblas），并解压编译执行，具体步骤如下：
首先建立一个文件夹用来盛放解压后的openblas
$mkdir openblas
$cd openblas
然后编译
$make
这个编译是多线程编译。编译好之后安装之
$sudo make install
安装后即可。
5.Caffe的安装和测试
将下载后的caffe-master.zip解压，并将解压后的文件放入要存放的目录，进入caffe-master目录，首先复制一份fig
fig
然后修改fig中的参数：
fig
主要修改的参数如下：
然后编译
make all-j4
make test
make runtest
最后看是否能通过编译。
6.在minist的数据包上训练测试
首先在根目录上获取数据集并解压
cd$CAFFE_ROOT
./data/mnist/get_mnist.sh
然后执行
./examples/mnist/create_mnist.sh
将数据格式转换为lmdb格式。并将新生成的2个文件mnist-train-lmdb和mnist-test-lmdb放于和create_mnist.sh相同目录下。
最后执行测试集，指令如下：
./examples/mnist/train_lenet.sh
到此为止即把caffe的安装测试工作完成了。
7.出现的部分问题及解决方法
1.在安装过程中出现：
linktest.c:(.text.startup+0x55ab):undefined reference to`LAPACKE_clagsy'

这种问题通过以下方法解决：
首先添加依赖库install-gcc-multilib install-gfortran-multilib libopenblas，然后执行make TARGET=BANIS SINARY=32即可解决问题。
