ValueError: not enough values to unpack (expected 3, got 2)

I try to run your project
but it can not be run

So this is an error

$ python3 main.py --videos videos
/Users/teamzoon/Downloads/Human-detection-and-Tracking-master/videos/6.mp4*.mp4
['/Users/teamzoon/Downloads/Human-detection-and-Tracking-master/videos/6.mp4']

Traceback (most recent call last):

ValueError: not enough values to unpack (expected 3, got 2)

Can you specify the version of OpenCV used by you?
It seems that you are getting the error because the function cv2.findContours is returning only two values instead of three values.
A possible cause will be you are using OpenCV version less than 3.0.

A possible solution is to remove the variable im2 at line no. 118, the change is given below:
im2, cnts, hierarchy = cv2.findContours(thresh.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE) ---> current line
cnts, hierarchy = cv2.findContours(thresh.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE) ---> changed line
