Hi,<br>
<br>
I'm using JdeRobot 5.5.2 and cloned the latest version of Academy.<br>
<br>
Currently working on the follow_turtlebot exercise and I'm encountering an<br>
error when running the follow_turtlebot component (./follow_turtlebot.py<br>
--Ice.Config=follow_turtlebot_<wbr>conf.cfg).<br>
<br>
The error I get is:<br>
<br>
File "/home/rafa/Academy/src/<wbr>follow_turtlebot/MyAlgorithm.<wbr>py", line 4, in<br>
<module><br>
import cv2<br>
ImportError: /opt/ros/kinetic/lib/python2.<wbr>7/dist-packages/cv2.so: undefined<br>
symbol: PyCObject_Type<br>
<br>
I reinstalled opencv-python but it didnt solve the problem.<br>
<br>
Did anyone encounter the same problem? If so, how did you solve it?<br>
<br>
Thanks,<br>
Rafa<br>
