I am running ROS Indigo on Ubuntu 14.04. I am trying to follow the camera calibration tutorial on the ROS Wiki.
http://wiki.ros.org/camera_calibration
I give the following command
> rosrun camera_calibration> cameracalibrator.py --size 8x6> --square 0.108 image:=/my_camera/image camera:=/my_camera
I get the following error
> ImportError: numpy.core.multiarray> failed to import Traceback (most> recent call last): File> "/opt/ros/indigo/lib/camera_calibration/cameracalibrator.py",> line 47, in > import cv2 ImportError: numpy.core.multiarray failed to import
I thought it was to do with updating numpy and did a rosdep update but no differnce.
What is a possible way to solve this problem.
