[JdeRobot] [jderobot] Error in import CV2

Hey Arturo,

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
http://jderobot.org/index.php/Manual-5#Installing_JdeRobot_5 ) 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.

Cheers :)

Hello,

The code you mention is in my .bashrc file. I send it attached.

Hi,

I have a similar issue:

ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined
symbol: PyCObject_Type

I tried <code>sudo apt-get dist-upgrade</code> and <code>sudo pip install
opencv-python</code> (also with pip3 just in case), but the problem
persist...

Any idea? Thanks in advance.
Regards.
