Installation issue with protobuf and caffe

Question

From the last 2 days, I have been trying to install caffe on OSX 10.10

I was able to run all the installation commands successfully for caffe but when I tried to import caffe in ipython I got the exact same error: https://github.com/BVLC/caffe/issues/2092

So, as suggested in the thread, I tried to downgrade protobuf from 3.0.0 to 2.6.1. I was successfully able to install protoc and the new version does say 2.6.1

But now I not able to install protobuf python library. I am following the instructions mentioned here: https://github.com/google/protobuf/tree/v2.6.1/python I get the following error while running the command python setup.py google_test:

from google.protobuf import descriptor_pb2

File "/path/to/protobuf-2.6.1/python/google/protobuf/descriptor_pb2.py", line 21, in module>

There isn't much on Google. Please help.

I'm using brew and pip and things work out fine, try a fresh install for protobuf 2.6.0 as follows :

# First, uninstall protobuf
# Then let's install protobuf 2.6.0 for Mac
brew install homebrew/versions/protobuf260
# And install the corresponding python library version
pip install protobuf==2.6.0

I used 2.6.0 here because 2.6.1 seems not yet available on brew.
