[JdeRobot] [jderobot] Error in import CV2

[JoseMaria Cañas Plaza]

Hi JoseAntonio,

that seems more an OpenCV problem than a JdeRobot one :-)

The "init done opengl support available" are warning messages
according to these webs [1][2]. Try to explore the OpenCV example
demos, like grabcut.py to check that OpenCV is working fine on your
machine.

Cheers,

JoseMaria
