OpenCV for GoPiGo3

#1

@rick.torzynski, thanks for venturing into the great virtual (env) unknown. I am not that courageous, so I am planning to install non virtual with a backup of my card prior to the installation.

I have been using OpenCV 2.4.9 on a desktop RaspberryPi for some time, but am planning to take whatever: “sudo pip install opencv-contrib-python” will install.

(Trying to shrink my 16GB backup so I can verify it with a 15.9GB card at the moment.)

Looking forward to hearing about your success,

Alan (otherwise known as CyclicalObsessive)

Alan,

Thanks for the message - I was successful in getting GoPiGo3 to run in the virtualenv. I just had to set PYTHONPATH in the virtual environment.

$ export PYTHONPATH=/home/pi/.local/lib/python3.5/site-packages/

and then run the update script:

$ curl -kL dexterindustries.com/update_gopigo3 | bash -s -- --user-local --bypass-gui-installation

from the /home/pi/Dexter folder

So I have successfully compiled and installed OpenCV 4.0.0 on my GoPiGo3 - now to have some fun with Face/Object detection and self-driving. I also have a Google Coral TPU USB Accelerator stick to use…

Regards,
Rick
