Caffe网络结构

网络定义文件net.prototxt，可以用工具画出网络结构。最快速的方法是使用netscope，粘贴内容后shift+回车就可以看结果了。

 

caffe也自带了网络结构绘制工具，以下是在windows下使用graphviz的操作步骤。

安装pydot。

pip install protobuf pydot

下载graphviz。解压并将bin添加到环境变量。

cd %PythonPath%
python draw_net.py ..\..\..\..\examples\mnist\lenet_train_test.prototxt ..\..\..\..\examples\mnist\lenet_train_test.png

 

结果如下。

 caffe运行记录及部分注释如下。
