This is the error

Traceback (most recent call last):
File "object_tracker.py", line 87, in

blob2 = cv2.dnn.blobFromImage(face_img, 1, (227, 227), MODEL_MEAN_VALUES, swapRB=False)
replace this with
blob2 = cv2.dnn.blobFromImage(frame, 1, (227, 227), MODEL_MEAN_VALUES, swapRB=False)

Hi yensan0512,

Try to uncomment line 58 at object_tracker.py frame = imutils.resize(frame, width=400).

BR.
