错误关键词：CUDNN_STATUS_RUNTIME_PREREQUISITE_MISSING
原因总结：cudnn版本问题
解决方案：下载新版caffe代码，将caffe/include/caffe/util/cudn.hpp文件替换成新版。

错误关键词：protobuf ××××××未定义的引用
原因总结：gcc的版本问题
解决方案：

• 首先，去/usr/bin 目录下找到gcc右键属性，看它的软连接指向何处，如果软链指的不是ｇｃｃ5.0删除它,同样的方式查看g++
• 代码：

sudo ln -s /usr/bin/gcc-5 /usr/bin/gcc
sudo ln -s /usr/bin/g++-5 /usr/bin/g++
sudo ldconfig`
