I know it is allmost 3 years back but worth the try. I have been using the CentroidTracker to track multiple objects in python implementation, but the tracker is not very efficient dealing with occlution so I am trying to use CSRT tracker with MultiTracker function of openCV, but run into the same problem as you that the attribute is not in the module. I have tryed with the leagcy prefix, but that is not present either. now I am using version 4.11.0 of the openCV. Have you guys been using this recently? I have tried all possible ways of reinstalling openCV and using the openCV-contrib- vetc. etc but nothing working. Any suggestions, GitHub Copilot is also exhausted on indeas!
