使用python编译caffe时出现问题，未定义对“std:：\uuxx11:：…”

Question

我曾经在ubuntu14.04上用PYTHON_LAYER:=1成功编译caffe。然后我切换到Ubuntu16.04，使用相同的设置但不同的内置软件，比如16.04版的g++5.4版，而不是14.04版的g++4.8版，我无法用python编译caffe。你能就这个问题给我一些建议吗？以下是我收到的错误消息的一部分

遵循cmake的官方安装说明可以解决此问题。在

解决方法：
1在您的CAFFE/目录中运行make clean
2compile_caffe_with_cmake的后续指令。在
