caffe学习系列（10）：如何测试caffe训练出来的模型

方法一:

caffe自带了测试命令，只需在caffe根目录输入：

~/caffe-master$ ./build/tools/caffe test\

 -model examples/mnist/lenet_train_test.prototxt \

-weights examples/mnist/lenet_iter_10000.caffemodel\

 -iterations 100

命令行解释：

./build/tools/caffe test ,表示只作预测（前向传播计算），不进行参数更新（后向传播计算）

-model examples/mnist/lenet_train_test.prototxt ，指定模型描述文本文件（可修改数据源位置，用自己制作的数据来测试）

-weights examples/mnist/lenet_iter_10000.caffemodel ，指定模型预先训练好的权值文件

-iterations 100 ，指定测试迭代次数，参与测试的样例数目为（iterations * batch_size）,

                         batch_size在model prototxt 里定义，设为100时刚好覆盖10000个测试样本

方法一的输出结果：

方法二：

在caffe的官方文件里面，就有classification.cpp作为demo。

如果自己建一个工程，首先需要把所有依赖库都加上。

包括：caffe（废话），boost，glog，gflag，hdf5，openblas，opencv，protobuf（后面这些事caffe要用的）

对于caffe，要把它的include文件夹和libcaffe.lib导入到工程里。

其他库由于nuget已经帮我们下好了，一样

1，在包含目录里添上：

../caffelib/include;

../caffelib/include/caffe/proto;

H:\NugetPackages\boost.1.59.0.0\lib\native\include;

H:\NugetPackages\gflags.2.1.2.1\build\native\include;

H:\NugetPackages\glog.0.3.3.0\build\native\include;

H:\NugetPackages\protobuf-v120.2.6.1\build\native\include;

H:\NugetPackages\OpenBLAS.0.2.14.1\lib\native\include;

H:\NugetPackages\OpenCV.2.4.10\build\native\include;

2，在库目录里添上

../caffelib/lib;

H:\NugetPackages\boost_date_time-vc120.1.59.0.0\lib\native\address-model-64\lib;

H:\NugetPackages\boost_filesystem-vc120.1.59.0.0\lib\native\address-model-64\lib;

H:\NugetPackages\boost_system-vc120.1.59.0.0\lib\native\address-model-64\lib;

H:\NugetPackages\boost_thread-vc120.1.59.0.0\lib\native\address-model-64\lib;

H:\NugetPackages\boost_chrono-vc120.1.59.0.0\lib\native\address-model-64\lib;

H:\NugetPackages\glog.0.3.3.0\build\native\lib\x64\v120\Release\dynamic;

H:\NugetPackages\protobuf-v120.2.6.1\build\native\lib\x64\v120\Release;

H:\NugetPackages\OpenBLAS.0.2.14.1\lib\native\lib\x64;

H:\NugetPackages\hdf5-v120-complete.1.8.15.2\lib\native\lib\x64;

H:\NugetPackages\OpenCV.2.4.10\build\native\lib\x64\v120\Release;

H:\NugetPackages\gflags.2.1.2.1\build\native\x64\v120\dynamic\Lib;

3，在附加依赖项里面添上

libcaffe.lib
libopenblas.dll.a
libprotobuf.lib
opencv_highgui2410.lib
opencv_core2410.lib
opencv_imgproc2410.lib
libglog.lib
gflags.lib
hdf5.lib
hdf5_hl.lib

然后把classification.cpp作为demo运行就可以了。当然，也可以根据需要修改这部分代码，不难。
