Windows下用VS2013加载caffemodel做图像分类
来源:互联网 发布:淘宝三际数码怎么样 编辑:程序博客网 时间:2024/05/17 09:27
本文假设你已经安装CUDA,CUDA版本是7.5。
1.编译caffe的Windows版本
happynear的博客已经介绍了如何在windows下编译caffe,这里把我自己编译的过程记录下来,也算是做做笔记,方便以后查看。
1.1下载caffe-windows-master
下载地址:caffe-windows-master
1.2下载第三方库
下载地址:3rdparty
1.3 解压
解压第三方库3rdparty,解压到caffe-windows-master中的3rdparty文件夹中,即caffe-windows-master/3rdparty中的内容为:
!!!然后,需要将bin文件夹加入环境变量中。
当然,如果嫌麻烦,下载我解压好的文件就行,跳过以上过程,下载该文件,下载地址:点击这里。
1.4 开始编译
双击caffe-windows-master\src\caffe\proto\extract_proto.bat,生成caffe.pb.h
和caffe.pb.cc
两个c++文件,和caffe_pb2.py
这个python使用的文件。然后,用vs2013打开./buildVS2013/MainBuilder.sln,打开之后切换编译模式至Release X64模式。如果你的CUDA版本不是7.5,打开之后可能显示加载失败,这时就要用记事本打开./buildVS2013/MSVC/MainBuilder.vcxproj,搜索CUDA 7.5,把这个7.5换成你自己的CUDA版本,就可以正常打开了。
右键caffelib项目,配置属性——>常规,将配置类型修改为应用程序(.exe),目标文件扩展名修改为.exe;接着:
C/C++ ——> 常规,附加包含目录修改如下(CUDA路径按自己的修改):
- ../../3rdparty/include
- ../../src
- ../../include
- C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\include
链接器 ——> 常规,附加库目录修改如下(CUDA路径按自己的修改):- C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\lib\x64
链接器——>输入;将cudnn64_65.lib修改成cudnn.lib
如果需要matlab和python接口,可参考如下设置(路径按自己的设置):Matcaffe项目:
附加包含目录:
- ../../3rdparty/include
- ../../src
- ../../include
- C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\include
- D:\Program Files\MATLAB\R2014a\extern\include
附加库目录:
- ../../3rdparty/lib
- C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\lib\x64
- D:\Program Files\MATLAB\R2014a\extern\lib\win64\microsoft
Pycaffe项目:
附加包含目录:
- ../../3rdparty/include
- ../../src
- ../../include
- C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\include
- D:\Python27\include
- D:\Python27\Lib\site-packages\numpy\core\include
附加库目录:
- ../../3rdparty/lib
- C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\lib\x64
- D:\Python27\libs
2.修改classification.cpp代码
右键caffelib,添加新建项classification.cpp,classification.cpp代码可参考如下:该代码逐张读取文件夹下的图像并将分类结果显示在图像左上角,空格下一张。
结果显示在左上角,有英文和中文两种标签可选,如果显示中文,需要使用Freetype库,请自行百度。

3.生成
设置好之后,右键caffelib,生成。
4.结果
左边是中文标签,右边是英文标签。
最后,可以删除那些不需要的文件或文件夹,如我的caffe-windows-master内只留下:
也可以下载我封装好的代码,可通过链接下载:http://download.csdn.net/detail/sinat_30071459/9568131 是一个txt文件,因为csdn上传限制,代码上传到了百度云,txt里面有百度云链接。下载解压后将Classification\CLassificationDLL\bin加入环境变量,然后加入你的模型文件即可。
