when I run

Traceback (most recent call last):

I have encounter the similar problem.
I am using anaconda2, and my problem is that I have installed multiple protobuf (conda install -c distributions libprotobuf=2.5.0, which is used for caffe compilation , and also pip install protobuf, which is 3.3.0 mistakenly installed at first).
So I used pip uninstall protobuf and successfully uninstalled protobuf-3.3.0, then the pycaffe import works.

I am too facing this issue. I have both anaconda2 and anaconda3 installed(i know its bad way to have both python version, but i had my own reasons.) I changed the makefile to point to python2 anaconda and installed caffe2. Now I am facing the same issue. Any one can suggest what may be the problem?
