Sistine.py in crash when I run it

[LolloMazzy]

I run with the command python2 sistine.py but the window with the picture of webcam, remains open for only 2 seconds.
In the terminal i can see this message:
Traceback (most recent call last): File "sistine.py", line 397, in <module> main() File "sistine.py", line 383, in main if not currStage(segmented, debugframe, options, ticks, drawframe, calib, state): File "sistine.py", line 223, in _calibration x, y, touch = find(segmented, debugframe=drawframe, options=options) File "sistine.py", line 152, in find _, cnts, _ = cv2.findContours(segmented_image.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE) ValueError: need more than 2 values to unpack

I have a similar issue. Followed instructs in readme and when I run sistine.py, getting a ValueError.
I'm running MacOS Mojave v10.14.5.

$ python2 sistine.py  
Traceback (most recent call last):

    _, cnts, _ = cv2.findContours(segmented_image.copy(), cv2.RETR_EXTERNAL,   cv2.CHAIN_APPROX_SIMPLE)

I've tried to change line152 to something like the below, and the sistine.py did not shut down

( cnts, _ )= cv2.findContours(segmented_image.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

This worked for me too.
