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 ........examplesmnistlenet_train_test.prototxt ........examplesmnistlenet_train_test.png
结果如下。
caffe运行记录及部分注释如下。
