Have the aruco module and it’s support been completely purged in latest OpenCV? I am simply unable to access the aruco module at all through _cv2.aruco_. I saw some posts mentioning that you dont need to access the modules functions through the aruco keyword anymore, but I cant find for example _Dictionary\_get_ or _detectMarkers_.  
And yes, I have installed opencv-contrib-python.

[issue](https://github.com/opencv/opencv/issues/23176)

and read this [post](https://forum.opencv.org/t/aruco-coordinate-system-changed-in-pose-estimation-for-opencv-4-6-4-7-bug-or-change-in-spec/12536)

try [this](https://github.com/opencv/opencv/issues/23176#issuecomment-1482803743) it may work if you build python binding yourself

have you installed any _other_ packages relating to OpenCV? if yes, that’s a problem.
