環境：windows 7+matlab2016a+vs2013

caffe下載地址：https://github.com/BVLC/caffe/tree/windows

1 進入caffe-windows的windows資料夾，Copy .\windows\CommonSettings.props.example to .\windows\CommonSettings.props

2 開啟caffe工程，編輯CommonSettings.props檔案，以下是cpu版本設定

        <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  選擇matcaffe專案，點選編譯（會自動去下載第三方庫），在Build\x64\Release會生成相應的檔案

4 將上面Build\x64\Release絕對路徑加入到系統環境path變數中，同時將Build\x64\Release\matcaffe加入到matlab路徑中。

5 重新啟動matlab，呼叫caffe.reset_all()，則說明ok。

>> caffe.reset_all();

python使用

下載安裝anaconda

安裝protobuf：在命令列輸入：pip install protobuf

使用spyder，並且設定Python路徑

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%畫圖用的 
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();%取訓練集的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();%取驗證集的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

測試

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');

微調

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;

iter_ = solver.iter();

    solver.step(1);
    iter_ = solver.iter();    
    loss=solver.net.blobs('loss').get_data();%取訓練集的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();%取驗證集的accuracy       
        if iter_/100 == 1

            drawnow

        end
    end
