I am running ROS Indigo on Ubuntu 14.04. I am doing a mono-camera calibration and trying to follow the camera calibration tutorial on the ROS Wiki.
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 difference.
What is a possible way to solve this problem?
UPDATE: I uninstalled and reinstalled ROS completely from scratch. I still get the same error. Should I have to look somewhere outside ROS?
