windows配置caffe及matlab/python接口编译和调用，cpu/gpu

环境：windows 7+matlab2016a+vs2013

caffe下载地址：https://github.com/BVLC/caffe/tree/windows

1 进入caffe-windows的windows文件夹，Copy .\windows\CommonSettings.props.example to .\windows\CommonSettings.props

2 打开caffe工程，编辑CommonSettings.props文件，以下是cpu版本设置

<CpuOnlyBuild>true</CpuOnlyBuild>

<UseCuDNN>false</UseCuDNN>

<CudaVersion>7.5</CudaVersion>

<PythonSupport>false</PythonSupport>

<MatlabSupport>true</MatlabSupport>

<CudaDependencies></CudaDependencies>

<PropertyGroup Condition="\'$(MatlabSupport)\'==\'true\'">

<MatlabDir>C:\Program Files\MATLAB\R2016a</MatlabDir>

<LibraryPath>$(MatlabDir)\extern\lib\win64\microsoft;$(LibraryPath)</LibraryPath>

<IncludePath>$(MatlabDir)\extern\include;$(IncludePath)</IncludePath>

</PropertyGroup>

3 选择matcaffe项目，点击编译（会自动去下载第三方库），在Build\x64\Release会生成相应的文件

4 将上面Build\x64\Release绝对路径加入到系统环境path变量中，同时将Build\x64\Release\matcaffe加入到matlab路径中。

5 重新启动matlab，调用caffe.reset_all()，则说明ok。

>> caffe.reset_all();

Cleared 0 solvers and 0 stand-alone nets

python使用

下载安装anaconda

安装protobuf：在命令行输入：pip install protobuf

使用spyder，并且设置Python路径

import caffe

caffe在matlab中使用：

function train()
solver_def_file = \'model/lenet_solver.prototxt\';
caffe.set_mode_cpu();
caffe.reset_all();
solver = caffe.Solver(solver_def_file);
% solver.solve();%一次性迭代

close all;
hold on%画图用的 
iter_ = solver.iter();
while iter_<10000
    solver.step(1);%一步一步迭代
    iter_ = solver.iter();    
    loss=solver.net.blobs(\'loss\').get_data();%取训练集的loss  
    if iter_==1
        loss_init = loss;
    else
        y_l=[loss_init loss];
        x_l=[iter_-1, iter_];     
        plot(x_l, y_l, \'r-\');
        drawnow
        loss_init = loss;
    end
    
    if mod(iter_, 100) == 0
        accuracy=solver.test_nets.blobs(\'accuracy\').get_data();%取验证集的accuracy       
        if iter_/100 == 1
            accuracy_init = accuracy;
        else 
            x_l=[iter_-100, iter_];
            y_a=[accuracy_init accuracy];
            plot(x_l, y_a,\'g-\');
            drawnow
            accuracy_init=accuracy;
        end
    end
end

测试

function test()
net = init_net();
im_data = 255-caffe.io.load_image(\'image/00082.png\');
res = net.forward({im_data});
[~, idx ]= max(res{1});
disp(idx-1);


function net = init_net()
caffe.set_mode_cpu();
caffe.reset_all();
deploy = \'model/lenet_deploy.prototxt\';
caffe_model = \'snapshot/lenet_iter_10000.caffemodel\';
net = caffe.Net(deploy, caffe_model, \'test\');

微调

function retrain()
caffe.set_mode_cpu();
caffe.reset_all();
caffe_model = \'snapshot/lenet_iter_10000.caffemodel\';
solver = caffe.Solver(\'model/lenet_solver.prototxt\');
solver.net.copy_from(caffe_model);
% solver.solve();

close all;
hold on%画图用的 
iter_ = solver.iter();
while iter_<10000
    solver.step(1);
    iter_ = solver.iter();    
    loss=solver.net.blobs(\'loss\').get_data();%取训练集的loss  
    if iter_==1
        loss_init = loss;
    else
        y_l=[loss_init loss];
        x_l=[iter_-1, iter_];     
        plot(x_l, y_l, \'r-\');
        drawnow
        loss_init = loss;
    end
    
    if mod(iter_, 100) == 0
        accuracy=solver.test_nets.blobs(\'accuracy\').get_data();%取验证集的accuracy       
        if iter_/100 == 1
            accuracy_init = accuracy;
        else 
            x_l=[iter_-100, iter_];
            y_a=[accuracy_init accuracy];
            plot(x_l, y_a,\'g-\');
            drawnow
            accuracy_init=accuracy;
        end
    end
end
