<div dir="auto">Hey Arturo, <div dir="auto"><br></div><div dir="auto">JdeRobot has released it's 5.5 version and I think it doesn't have open CV as a dependency. It comes along with it. I think a fresh install of it ( instructions at <a href="http://jderobot.org/index.php/Manual-5#Installing_JdeRobot_5">http://jderobot.org/index.php/Manual-5#Installing_JdeRobot_5</a> ) should solve all problems. Make sure you have Ubuntu 16.04 Xenial 64bit or a stable Debian distribution. Make sure to have the pre requisites in the link.</div><div dir="auto"><br></div><div dir="auto">Cheers :)</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mar 21, 2017 11:58 PM, <<a href="mailto:jde-developers-request@gsyc.urjc.es">jde-developers-request@gsyc.urjc.es</a>> wrote:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Send Jde-developers mailing list submissions to<br>

Hi,<br>
<br>
I have a similar issue:<br>
<br>
ImportError: /opt/ros/kinetic/lib/python2.<wbr>7/dist-packages/cv2.so: undefined<br>
symbol: PyCObject_Type<br>
<br>
I tried <code>sudo apt-get dist-upgrade</code> and <code>sudo pip install<br>
opencv-python</code> (also with pip3 just in case), but the problem<br>
persist...<br>
<br>
Any idea? Thanks in advance.<br>
Regards.<br>
