【20200404更新】关于如何将matlab训练的深度学习网络进行c代码生成
文章目录
按照官方教程使用cmake编译出的mkldnn内库文件为x64文件，若尝试使用这些DLL在VS中编译x86工程会报错。
但在cmake编译时设定编译x86的DLL文件呢？（待试）
0. 环境配置

Prerequisites for Deep Learning with MATLAB Coder
https://www.mathworks.com/help/coder/ug/prerequisites-for-deep-learning-with-matlab-coder.html
下载mkl-dnn（这是老版本，新版本更改了名字
https://github.com/intel/mkl-dnn）
安装CMAKE
https://www.cnblogs.com/saucerman/articles/5608134.html
WIN下安装CMAKE
https://blog.csdn.net/u011231598/article/details/80338941
且网页内的这一步，貌似缺少了一个文件，mklbl.lib也需要复制到文件夹内，否则会导致这个错误
安装matlab内的coder支持，就是下图的这个玩意
1.正文，干活(大号字体说一句：CODER真的好慢啊！！！！！！！！！）
1.1 方法1，基于matlab自带的封面为辣椒的例子修改
这里使用了VGG16的深度学习网络。请自行在matlab内安装。图片使用这只小喵喵（我也不知道是什么品种，VGG16网络也不知道，哈哈哈哈）
函数如下
function y = ff(im) %输入im为224*224*3的UINT8图片数据
persistent mynet ;
if isempty(mynet)
mynet = coder.loadDeepLearningNetwork('vgg16');
end
y = predict(mynet,im)';
end
啰嗦一句，如下两个命令必须确认是否已经运行，否则无法识别mkldnn.dll。编译报错
setenv('INTEL_MKLDNN', 'C:\Program Files\mkl-dnn\')
setenv('PATH', [getenv('INTEL_MKLDNN') filesep 'lib' pathsep getenv('PATH')])
为 ff 函数生成 MEX 代码。
要从ff.m 函数生成 MEX 函数，请将 codegen 与针对 MKL-DNN 库创建的深度学习配置对象结合使用。将该深度学习配置对象附加到传递给 codegen 的 MEX 代码生成配置对象。
cfg = coder.config('mex');
cfg.TargetLang = 'C++';
cfg.DeepLearningConfig = coder.DeepLearningConfig('mkldnn');
codegen -config cfgff -args {ones(224,224,3,'single')} -report
对测试图像调用 predict，可见283号的概率为最大。283号为tiger cat
im = imread('test.png');
im = imresize(im, [224,224]);
imshow(im);
predict_scores = ff_mex(single(im));
为 resnet_predict 函数生成静态库
要从 resnet_predict.m 函数生成静态库，请将 codegen 与针对 MKL-DNN 库创建的深度学习配置对象结合使用。将该深度学习配置对象附加到传递给 codegen 的代码生成配置对象。
cfg = coder.config('lib');
cfg.TargetLang = 'C++';
cfg.DeepLearningConfig = coder.DeepLearningConfig('mkldnn');
codegen -config cfg ff -args {ones(224,224,3,'single')} -report
%
codegendir = fullfile(pwd, 'codegen', 'lib', 'ff');
1.2方法2
这里使用了VGG16的深度学习网络。请自行在matlab内安装。
一般的，m文件内结果输出使用classify函数，但该函数不支持coder。
使用predict函数代替，输出各categories的概率，找到最大概率值对应的class，即为分类结果
function y = f(im) %输入im为224*224*3的UINT8图片数据

persistent mynet ;
if isempty(mynet)
mynet = coder.loadDeepLearningNetwork('vgg16');
end
possibility = predict(mynet,im)';
number = find(possibility == max(possibility));
y = classes{number(1),1};
end
这结果也行吧，至少能够识别是个喵呀！！手动无奈。
打开coder吧，看图说话
这里有几个警告，不知道为什么，也不知道有没有影响。先放在这吧
CODER完成，依然有警告信息。不过可以看见：f.c已经生成
3.最后啰嗦一点
不要忘记吧mkldnn的库和深度网络的相关文件放入文件夹，否则是无法运行的
同理，在LABVIEW内运行，也是需要吧mkldnn内的dll和lib文件放到文件夹内。
识别结果为282，也就是第283个类别概率最大。283为tiger cat。正确
