1. 问题描述

使用ananconda安装好opencv之后发现出现了这种问题：

import cv2

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-3-c8ec22b3e787> in <module>
----> 1 import cv2ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type

原因在于ROS安装之后的~/.bashrc文件中多出一句：
source /opt/ros/kinetic/setup.bash

2. 处理方法

因为是受ROS安装的影响，所以考虑

sys.path.remove('/opt/ros/kinetic/lib/python2.7/dist-packages')

在python文件中 import cv2 时改为下面这样就可以了。

import sys
ros_path = '/opt/ros/kinetic/lib/python2.7/dist-packages'
if ros_path in sys.path:sys.path.remove(ros_path)
import cv2
sys.path.append('/opt/ros/kinetic/lib/python2.7/dist-packages')
