Two errors that I came across

[imr555]

After pulling the latest version and running the code on the sample I came across this error

Traceback (most recent call last):
File "track.py", line 252, in <module>
floorCrop(filename)
File "track.py", line 91, in floorCrop
contours, hierarchy = cv2.findContours(mask, cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE)
ValueError: too many values to unpack (expected 2)

Adding _, and a space before line 91, like this _, contours, hierarchy = cv2.findContours(mask, cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)`

I achieve another error sadly.This error comes after drawing a box around the rat,

Segmentation fault (core dumped)

@imr555, please pull new version.

• The 1st error is caused by version < 4.0.0.21 of your OpenCV, run pip install -r requirements.txt.
• The 2nd one is caused by conflict between cv2.waitKey() and cv2.destroyWindow(). It was okay on Windows but not on Mac OS X or Linux.

The previous issues are resolved. But theres a new error that has come up. After running the code twice each time at 120 sec, the program auto exits and this error shows up

Traceback (most recent call last):
  File "track.py", line 255, in <module>
    trace(filename)
  File "track.py", line 180, in trace
    x = int(M['m10']/M['m00'])
ZeroDivisionError: float division by zero

Yes, it's fixed too in c560eb0.
