While i initialize traker:

is_track = tracker.init(frame, track_frame)
if is_track:
    print("Tracker initialized!!!!!")
else:
    print("It isn't work")

Whie it work, it gone to inscription “It isn’t work”. Several times i has cheked the ‘frame’ and ‘track_frame’, but it hasn’t work yet.

My frame:

frame = path.read()

My track_frame:

x,y = clic_coordinates
track_frame = (x - 30 , y - 25 , 60, 50)

By these coordinates it buits a rectangle (correct, that shape i want)
cv2.rectangle(frame, (x-30, y-25), (x + 30,y+ 25), (0, 255, 0), 2, 1)

And the whole code:

path = cv2.VideoCapture(0)  #
clic_coordinates = None
coordinate_x=None
coordinate_y=None
condition=True
clicked=False


# Function for processing cliking on mause
def clicked_coordinates(event, x, y, flags, param):
    global clic_coordinates
    if event == cv2.EVENT_LBUTTONDOWN:
        clic_coordinates = (x,y)
        clicked = True
    if event == cv2.EVENT_RBUTTONDOWN:
        condition=False

tracker= cv2.TrackerKCF_create()   #tracker type   
if tracker is None:
    print("Tracker initialized incorrectly")
area_track=None
is_track = False


iteration=0

cv2.namedWindow("Tracking")
cv2.setMouseCallback("Tracking",clicked_coordinates)

while condition:
    ret, frame = path.read()
    if not ret:
        break
    #cv2.imshow("Tracking",frame)

    if is_track:
        print("HERE GO!!!")
        is_track, area_track=tracker.update(frame)
        if is_track:
            (x, y, w, h) = [int(v) for v in area_track]
            cv2.rectangle(frame, (x, y), (x + w, y + h), (0, 255, 0), 2, 1)
    else:
        cv2.putText(frame, "Object is not tracked", (50, 80), cv2.FONT_HERSHEY_SIMPLEX, 0.75, (0, 0, 255), 2)


    if (clicked or clic_coordinates is not None):
        x,y = clic_coordinates
        track_frame = (x - 30 , y - 25 , 60, 50)
        cv2.rectangle(frame, (x-30, y-25), (x + 30,y+ 25), (0, 255, 0), 2, 1)
        clicked=False
        clic_coordinates=None
        #cv2.imshow("Tracking", frame)
        if track_frame is not None:
            print("region for track is ok: " , track_frame)
        if frame is not None:
            print(f"Frame size: {frame.size}")
            print("Frame ok")
        try:
        #    ret, frame = path.read()
         #   if ret:
                is_track = tracker.init(frame, track_frame)
                if is_track:
                    print("Tracker initialized!!!!!")
                else:
                    print("It isn't work(")
        except cv2.error:
            print(f"OpenCV error: ")
        print("Tracker hasn't initialized but go")
        cv2.imshow("Tracking", frame)


    if cv2.waitKey(300) & 0xFF == ord('q'):
        condition=False
        break
    cv2.imshow("Tracking", frame)

I tried everything chatGPT offered, blackbox offered: to chek frame and track_frame, to change the tracker (for example for MIL), displayed on the screen a both frames. The only hope is this forume(
