Creating a new HAND_CONNECTIONS in python

[Borzborz]

Hello, I wanted to create a new hand connection frozenset in hands.py like so:

HAND_TIP_CONNECTIONS = frozenset([
    (HandLandmark.THUMB_TIP,HandLandmark.INDEX_FINGER_TIP),
    (HandLandmark.INDEX_FINGER_TIP,HandLandmark.MIDDLE_FINGER_TIP),
    (HandLandmark.MIDDLE_FINGER_TIP,HandLandmark.RING_FINGER_TIP),
    (HandLandmark.RING_FINGER_TIP,HandLandmark.PINKY_TIP),
    (HandLandmark.PINKY_TIP,HandLandmark.WRIST),
    (HandLandmark.WRIST,HandLandmark.THUMB_TIP)
    ])

I wanted to do this so I can connect the tips of the fingers along with the wrist landmark when I use draw_landmarks. However, when I save the change to hands.py and try to call draw_landmarks in my code like so : mp_drawing.draw_landmarks(frame, hand_landmarks, mp_hands.HAND_TIP_CONNECTIONS) my code get an error saying

File "handGesture.py", line 49, in <module>
    mp_drawing.draw_landmarks(frame, hand_landmarks, mp_hands.HAND_TIP_CONNECTIONS)
AttributeError: module 'mediapipe.python.solutions.hands' has no attribute 'HAND_TIP_CONNECTIONS'

I'm not sure what to do here. Any suggestions on how I can create a new connection would be much appreciated.

If you modify the source code, you probably need to rerun the setup workflow to generate the package?

In fact, instead of touching hands.py, you can define HAND_TIP_CONNECTIONS in your python code and pass it to draw_landmarks().
