cv_bridge dynamic module does not define module (PyInit_cv_bridge_boost)

Problems in using cv_bridge to convert ROS image to OpenCV image.

I created a virtual environment with Python 3.7.2 and OpenCV. I can import by using "import cv2"

The problem is in this line:

cv_image = self.bridge.imgmsg_to_cv2(data,"bgr8")

What I want to do is to get an image from ROS topic and display in cv2.imshow

ImportError: dynamic module does not define module export function (PyInit_cv_bridge_boost)

Solution

  • Even though opencv2 could be import in python 3.7, there were some problems in using cv_bridge library. Solved by running my code using python older version (2.7). (python2 code_name.py)
