Dear Sir/Madam,
I got following error when I run first block of Object Following sample.
What seems to be the problem ?
I am using Sparkfun Jetbot Image from https://learn.sparkfun.com/tutorials/as … rom-nvidia .
from jetbot import ObjectDetector
model = ObjectDetector(‘ssd_mobilenet_v2_coco.engine’)
AttributeError Traceback (most recent call last)
