1、环境:windows 7\VS2013
2、caffe-windows准备
(1)下载官方caffe-windows并解压,将 .\windows\CommonSettings.props.example备份,并改名为CommonSettings.props。如图4所示:
图 4:修改后的CommonSettings.props文件
附带说明,现在最新版的github已经更新,没有上述文件,根据大佬说法用cmake编译后能产生sln文件,笔者不才,并不会,这里提供百度云盘的老版本:

(2)关于CommonSettings.props文件的一点说明。

3、编译caffe-windows
编译用vs2013打开.\windows\Caffe.sln 并将解决方案的配置改为release,点菜单栏上的“生成->生成解决方案”,会将整个项目全部生成,这个时间会比较长(由于官方caffe-windows 的版本使用了NuGet管理第三方开发包,所以需要在vs2013上安装NuGet,官方网站下载速度比较慢,可以在我的资源里下载)。生成成功之后的文件都在.\Build\x64\Release中。
PS:生成时可能遇到的错误:errorC2220: 警告被视为错误 - 没有生成“object”文件 (..\..\src\caffe\util\math_functions.cpp)。这个错误可参考Sunshine_in_Moon 的解决方案。
4、测试
1)下载MNIST数据集,MNIST数据集包含四个文件,如表1所示:
表1:MNIST数据集及其文件解释
文件 |
内容 |
训练集图片 - 55000 张 训练图片, 5000 张 验证图片 |
|
训练集图片对应的数字标签 |
|
测试集图片 - 10000 张 图片 |
|
测试集图片对应的数字标签 |
2)转换 训练\测试数据
a) 中的四个文件放到 . \examples\mnist\mnist_data文件夹下。
b) 在caffe-windows安装的根目录下,新建一个convert-mnist-data-train.bat文件转换为训练数据,并在文件中添加代码:
- Build\x64\Release\convert_mnist_data.exe --backend=lmdbexamples\mnist\mnist_data\train-images.idx3-ubyteexamples\mnist\mnist_data\train-labels.idx1-ubyte examples\mnist\mnist_data\mnist_train_lmdb
- pause
其中--backend=lmdb 表示转换为lmdb格式,若要转换为leveldb将其改写为--backend=leveldb 即可。
再新建一个convert-mnist-data-test.bat转换测试数据,代码为:
- Build\x64\Release\convert_mnist_data.exe --backend=lmdb examples\mnist\mnist_data\t10k-images.idx3-ubyte examples\mnist\mnist_data\t10k-labels.idx1-ubyte examples\mnist\mnist_data\mnist_test_lmdb
- Pause
Ps:(1)convert_mnist_data.exe的命令格式为:
convert_mnist_data [FLAGS] input_image_file input_label_file output_db_file
[FLAGS]:转换的文件格式可取leveldb或lmdb,示例:--backend=leveldb
Input_image_file:输入的图片文件,示例:train-images.idx3-ubyte
input_label_file:输入的图片标签文件,示例:train-labels.idx1-ubyte
output:保存输出文件的文件夹,示例:mnist_train_lmdb
(2)如果感觉很麻烦,也可以直接下载我转换好的MNIST文件(leveldb和lmdb)。
3)运行测试
(1)将第2)步中转换好的训练\测试数据集(mnist_train_lmdb\ mnist_train_lmdb或mnist_train_leveldb\mnist_train_leveldb)文件夹放在.\examples\mnist中。
(2)在caffe-windows根目录下新建一个run.bat,文件中代码:
- Build\x64\Release\caffe.exe train --solver=examples/mnist/lenet_solver.prototxt
- pause
保存并双击运行,如果运行成功,说明caffe配置成功了。
注意1:使用leveldb或lmdb格式的数据时,需要将lenet_train_test.prototxt 文件里面的data_param-> source和data_param-> backend相对应,如图5红框所标注处。
图 5:lenet_train_test.prototxt文件中需要注意与训练\测试数据对应的部分
注意2:将lenet_solver.prototxt 文件里面的最后一行改为solver_mode:CPU。
4)训练自己的数据
