I'm trying to start working with openCV but keep getting an attribute error: module 'cv2.cv2' has no attribute 'TrackerKCF_create'

Sure thing, I’m class but will post it in half an hour.

import cv2
import sys

(major_ver, minor_ver, subminor_ver) = (cv2.__version__).split('.')

if __name__ == '__main__' :

# Set up tracker.
# Instead of MIL, you can also use

tracker_types = ['BOOSTING', 'MIL','KCF', 'TLD', 'MEDIANFLOW', 'GOTURN', 'CSRT']
tracker_type = tracker_types[2]

    if int(minor_ver) < 3:
        tracker = cv2.Tracker_create(tracker_type)
    else:
        if tracker_type == 'BOOSTING':
            tracker = cv2.TrackerBoosting_create()

        k = cv2.waitKey(1) & 0xff
        if k == 27 : break

Sorry if the formatting is weird, I'm not used to using reddit code syntax.
