Issue summary

I am trying to install Caffe (which is required by another github project installation https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation.md) however when I begin to install cafe it gives me the error: In file included from /Users/sreeharirammohan/Desktop/openpose/build/caffe/src/openpose_caffe-build/include/caffe/proto/caffe.pb.cc:4: /Users/sreeharirammohan/Desktop/openpose/build/caffe/src/openpose_caffe-build/include/caffe/proto/caffe.pb.h:17:2: error: This file was generated by an older version of protoc which is #error This file was generated by an older version of protoc which is ^ /Users/sreeharirammohan/Desktop/openpose/build/caffe/src/openpose_caffe-build/include/caffe/proto/caffe.pb.h:18:2: error: incompatible with your Protocol Buffer headers.

steps to reproduce

download the anaconda libprotobuf and protobuf packages and attempt to build caffe using these instructions (https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation.md)

My conda version is 4.5.11 My libprotobuf version is 3.6.0 My protobuf version is 3.6.0

Tried solutions

Here is what I think is happening based on this thread (https://github.com/BVLC/caffe/issues/5645#issuecomment-418208179) my anaconda versions of libprotobuf and protobuf are messing with the installation of caffe. A post in the above thread told me to simply uninstall them (but I can't because I have other projects on my laptop which require them). I need to somehow be able to create an environment without the conda versions of protobuf and libprotobuf for this project installation. I now a virtual environment would be perfect for this scenario but I have tried and failed to do it multiple times.
