I wrote a program to test opencv trackers but I got error. Here is my python code using opencv 4.10.0:

i’m using OpenCV for a school project using OpenCV for some object tracking.

(not using blackbox like these trackers would be better for my project).

This is my first time learning about object tracking and the example given was about object tracking in video using opencv. The code provided by my lecturer doesnt work and it doesnt help that he gave it when the class is about to end and he said to test it. Code provided :
