Several issues with compiling Caffe2 on Mac OSX without GPU

This issue appears just by importing pycaffe in the alexnet notebook.
Here is the dump from the crash.

Hi @AKSHAYUBHAT - could you let me know your opencv version? opencv_imgcodecs does not exist on my machine but I am using opencv 2, so I am wondering if it is a new target introduced in the new opencv 3 - in which case we should change the BREW file to support opencv3 as well.

Regarding the protobuf: there is a flag to force the use of system protobuf:

https://github.com/Yangqing/caffe2/blob/master/build_env.py#L18

Not sure if that solves your problem, but maybe give it a try? The whole build script is kind of experimental for now, so a bit cleaning might be needed.

pkg-config --modversion opencv
3.0.0

Regarding using system protobuf, I manually edited out the protobuf to force it to use system protobuf.
Even then it gave me the same error.

Here is my edited caffe_python.cc
https://github.com/AKSHAYUBHAT/DeepLearning/blob/master/caffe2/pycaffe2/caffe2_python.cc
The fatal exception occurs in libcaffe2_python_nogpu.so

Looking at following two issues It might be due to my system:
BVLC/caffe#1917
rbgirshick/py-faster-rcnn#24
