I am getting the following compilation error on OpenCV 4.5.1:
Generator error: class Tracker (cname=cv::Tracker) already exists
I am trying to compule with Cuda and CudaNN and am using python 3.8.5
Any help would be greatly appreciated. Thank you!

I was able to fix it myself. I think it was some issues with some tags I set. My current issue that I am unsure how to set it up so that python3 uses the opencv I compiled from source. When I run print(cv2.getBuildInformation()), it still says the stuff from before; running ‘cmake …’ in the opencv folder I have shows that it is compiled with cuda 11.2. It does say ’ install path: lib/python3.8/dist-packages/cv2/python-3.8’ when I check ccmake so I am not sure why it is still printing the wrong thing.
I was able to fix python3 stuff as well. I just needed to uninstall opencv-python by running pip3 uninstall opencv-python and remake and sudo make install. Thank you for offering your help!
