Caffe安装中多版本protobuf选择问题，版本过高

在ubuntu下安装caffe时，使用make all命令后，经常会报出protobuf版本冲突的问题，如下：

In file included from .build_release/src/caffe/proto/caffe.pb.cc:5:0:
.build_release/src/caffe/proto/caffe.pb.h:12:2: error: #error This file was generated by a newer version of protoc which is
 #error This file was generated by a newer version of protoc which is
  ^
.build_release/src/caffe/proto/caffe.pb.h:13:2: error: #error incompatible with your Protocol Buffer headers. Please update
 #error incompatible with your Protocol Buffer headers.  Please update
  ^
.build_release/src/caffe/proto/caffe.pb.h:14:2: error: #error your headers.
 #error your headers.
  ^
  ...

这个问题的出现是因为我们在安装caffe之前，安装Anaconda或tensorflow时都已经安装过libprotobuf

所以解决冲突的方法是使用以下命令：

conda uninstall libprotobuf

即可解决
