AttributeError: type object 'object' has no attribute '__getattr__'

[shahimanish87]

Hi,

I am trying to use the interaction box to scale down the coordinates captured by the leap using the normalized_point(). I followed the steps from here: https://developer-archive.leapmotion.com/documentation/python/api/Leap.InteractionBox.html.

However, I have the following error:
File "/home/eeyms8/Leap/Leap.py", line 66, in swiggetattr_nondynamic
return object.getattr(self, name)
AttributeError: type object 'object' has no attribute 'getattr'

This is the code i am running:

import Leap, sys, thread, time, ctypes
from Leap import KeyTapGesture

class LeapMotionListener(Leap.Listener):
finger_names = ['Thumb', 'Index', 'Middle', 'Ring', 'Pinky']
bone_names = ['Metacarpal', 'Proximal', 'Intermediate', 'Distal']
state_names = ['STATE-INVALID', 'STATE_START', 'STATE_UPDATE', 'STATE_END']

def on_init(self, controller):
    print "Initialized"  

    #opens file in write mode which clears the previous data saved on the file 
    data_file = open('data.txt', 'w')
    data_file.close()

def on_exit(self, controller):
    print "Exited"

def on_connect(self, controller):
    print "Connected"

    controller.enable_gesture(Leap.Gesture.TYPE_KEY_TAP);

def on_disconnect(self, controller):
    print "Disconnected"

def on_frame(self, controller):
    frame = controller.frame()

    print "Frame ID: " + str(frame.id) 

    # checks for the numbers of hands detected by the leap and issues a warning if more than one hand is detected
    numofHands = str(len(frame.hands))
    if numofHands == "2": 
       print "Please only use one hand"

    for hand in frame.hands:
        handType = "Left Hand" if hand.is_left else "Right Hand"
        
        #averages the palm postion from the last 10 frames 
        count = 0
        average = Leap.Vector()
        hand_to_average = frame.hands[0]
        for i in range(0,9):
            hand_from_frame = controller.frame(i).hand(hand_to_average.id)
            if(hand_from_frame.is_valid):
                average =  average + hand_from_frame.palm_position
                count +=1 
        average = average/count 
        #print average

    iBox = frame.interaction_box
    if iBox.is_valid:
            end_point = hand.palm_position
            normalizedPoint = iBox.normalized_point(end_point, True)
            print normalizedPoint

def main():
listener = LeapMotionListener()
controller = Leap.Controller()

controller.add_listener(listener)  
print "Press enter to quit"
try:
    sys.stdin.readline()
except KeyboardInterrupt:
    pass
finally:
    controller.remove_listener(listener)

if name == "main":
main()

I am using LeapMotion SDK Version 2.3.1+31549 with python 2.7.17 on Linux Ubuntu 18.04.4 LTS. I tried the solution mentined here: https://forums.leapmotion.com/t/leap-py-line-66-in--swig-getattr-nondynamic/5324
But it still doesn't work.

Thanks for your help in advance!
