编译 Caffe：对 `PyString_FromString' 的未定义引用

Question

我正在尝试从官方 GitHub 来源编译 Caffe + 使用用户添加的几个层 cpp 文件。编译时出现以下错误：

f@f-VirtualBox:~/caffe/mts4/caffe-master$ sudo make all
CXX/LD -o .build_release/tools/caffe.bin

编译错误意味着至少有一些用户添加或更改的cpp文件使用了Python。要解决此问题，您应该在编译前取消注释 Makefile.config 中的 WITH_PYTHON_LAYER := 1。
