最近因之前的服务器上的caffe奔溃了，不得已重新安装这一古老的深度学习框架，之前也尝试了好几次，每次都失败，这次总算是成功了，因此及时地总结一下。

以下安装的caffe主要是针对之前虹膜分割和巩膜分割所需的caffe版本。之前已经出过一个安装指南，部分内容与之重叠。

其实整个caffe安装最困难的部分就是各个依赖软件的安装，因此我们只要把这部分安装好了就可以了。

注意：安装指南，请参考《深度学习：21天实战caffe》的第5天那一章，只要按照上面所说的，将所有依赖文件安装在一个目录下，即可。最后安装好的列表应该为：

最后，修改caffe目录下的Makefile.config，找到如下几行：

# Whatever else you find you need goes here.
INCLUDE_DIRS :=/home/caiyong.wang/bin/caffe_local_install/include  $(PYTHON_INCLUDE)    /usr/local/include   
LIBRARY_DIRS :=/home/caiyong.wang/bin/caffe_local_install/lib  $(PYTHON_LIB)   /usr/local/lib /usr/lib  

完整的Makefile.config参考：

下面是一些细节：

1. 首先必须安装python2, 推荐直接安装anaconda2, 例如：https://repo.anaconda.com/archive/Anaconda2-5.0.0.1-Linux-x86_64.sh ，并添加路径到PATH环境变量。

2. opencv的安装
对于opencv,需要安装两个版本，一个是python的，一个是系统的。

对于python，可以安装 

pip install opencv-python==4.2.0.34

直接安装pip install opencv-python,可能出现 “ModuleNotFoundError: No module named 'skbuild' #105”，因此推荐降级安装。

参考：https://github.com/openvinotoolkit/dlstreamer_gst/issues/105

对于系统的安装，方法为：

opencv一般安装opencv 2.4.9, 首先下载opencv-2.4.9.zip源码，并解压：

unzip opencv-2.4.9.zip
cd opencv-2.4.9/
mkdir build;
cd build/
cmake ..
ccmake ..

这里要用到cmake与ccmake，可以自己安装，参考： https://www.24kplus.com/linux/557.html

https://www.cnblogs.com/tosser/p/9905597.html

https://blog.csdn.net/sheqianweilong/article/details/102582668

注意编译过程中需要加入： 

./bootstrap --prefix=/usr --datadir=share/cmake --docdir=doc/cmake --qt-gui && make // 参数--qt-gui是安装cmake-gui，不想安装可以省略

 继续回到opencv的安装，注意在caffe中仅仅使用图像读取和缩放等在CPU上的简单模块，因此可以禁用大部分无关模块以节省编译时间。

然后进行编译安装，

make && make install

至此安装成功。安装成功后，可以将opencv涉及到的bin,lib,pkgconfig填到~/.bashrc，

export PATH=/home/caiyong.wang/bin/caffe_local_install/bin:$PATH
export LD_LIBRARY_PATH=/home/caiyong.wang/bin/caffe_local_install/lib/:$LD_LIBRARY_PATH
 export PKG_CONFIG_PATH=/home/caiyong.wang/bin/caffe_local_install/lib/pkgconfig/:$PKG_CONFIG_PATH

然后source ~/.bashrc刷新。

opencv安装成功后，可以运行以下的程序进行测试，测试通过后，证明opencv安装成功，可以顺利安装caffe.

先编辑一个main函数，命名为main.cpp：

#include <stdio.h>  
#include <opencv2/opencv.hpp>
using namespace cv;
int main(void)  
{  
    printf("%s\r\n", CV_VERSION);  
    printf("%u.%u.%u\r\n", CV_MAJOR_VERSION, CV_MINOR_VERSION, CV_SUBMINOR_VERSION);  
}  

然后执行：

 g++ -o main main.cpp `pkg-config opencv --cflags --libs`

最后执行： ./main 

PS：对于pkgconfig的一些用法，如下：

[caiyong.wang@omnisky opencv_test]$ pkg-config --cflags opencv
-I/home/caiyong.wang/bin/caffe_local_install/include/opencv -I/home/caiyong.wang/bin/caffe_local_install/include
[caiyong.wang@omnisky opencv_test]$ pkg-config --libs opencv
/home/caiyong.wang/bin/caffe_local_install/lib/libopencv_calib3d.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_core.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_features2d.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_flann.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_highgui.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_imgproc.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_ml.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_objdetect.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_photo.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_stitching.so /home/caiyong.wang/bin/caffe_local_install/lib/libopencv_ts.a -lrt -lpthread -lm -ldl

 

3. protobuf的安装

同上，也必须安装两个版本，一个是python，一个是系统。

python安装： 直接pip install protobuf或者conda install protobuf。

系统安装：参考：https://wangcaiyong.blog.csdn.net/article/details/78283336
