最近安装caffe，突然报这个错：

发现又是protoc的版本不对。
查了下：
sensetime@sensetime-To-be-filled-by-O-E-M:/home/zenggq/mainspace/mscnn$ which protoc
/usr/bin/protoc
sensetime@sensetime-To-be-filled-by-O-E-M:/home/zenggq/mainspace/mscnn$
sensetime@sensetime-To-be-filled-by-O-E-M:~/zenggq/caffe-bak$ pip show protobuf

protoc --version
发现是2.5.0
索性把anaconda2下的protoc文件覆盖/usr/bin/protoc。
搞定。
