1. 使用gdb直接调试工程
配置参考：Caffe源码调试
主要打开：修改Makefile.config：DEBUG := 1 ；生成如下目录：
lrwxrwxrwx root root 1月 : build -> .build_debug/
drwxr-xr-x root root 1月 : .build_debug/
drwxr-xr-x root root 1月 : .build_release/
使用GDB启动调试，执行gdb --args build/tools/caffe train --solver examples/mnist/lenet_solver.prototxt ；可以直接调试；
rjw@rjw:~/caffe$ gdb --args build/tools/caffe train --solver examples/mnist/lenet_solver.prototxt

2. 使用Vscode进行调试：
配置c_cpp_properties.json 和launch.json ;
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
