segnet检测问题

File "example/Scripts/test_segmentation_camvid.py", line 14, in <module>

import caffe

File "./python/caffe/__init__.py", line 1, in <module>

from .pycaffe import Net, SGDSolver

File "./python/caffe/pycaffe.py", line 14, in <module>

import caffe.io

File "./python/caffe/io.py", line 8, in <module>

from caffe.proto import caffe_pb2

File "./python/caffe/proto/caffe_pb2.py", line 4, in <module>

from google.protobuf.internal import enum_type_wrapper

ImportError: No module named google.protobuf.internal

解决方法：直接在终端中安装protobuf，代码：pip install protobuf。（好像安装了2.6.1），但是我之前装过了2.5.0，安装方法大概是http://my.oschina.net/zhangjie830621/blog/412831，用protoc
--version查询版本后也是2.5.0，显示libprotoc 2.5.0，不知道什么鬼

第二个问题：

raceback (most recent call last):

File "example/Scripts/webcam_demo.py", line 7, in <module>

import cv2

ImportError: No module named cv2

pip install cv2

并没有什么用！

最后发现：
http://answers.opencv.org/question/58626/opencv-with-python-on-a-mac/
apt-get install python-opencv(好像是)

然后把cv2.so拷到/usr/local/lib/python2.7/site-packages里，然后在~/.bashrc里面添加这个路径，重新打开console，再运行就好啦，成功！！
