I think this line should be

frame_adjusted = np.ndarray(shape=np.shape(frame), dtype=np.dtype(np.uint8))

frame_adjusted[:,:,:] = frame[:,:,2::-1]
x, y, w, h = int(bbox[0]), int(bbox[1]), int(bbox[2]), int(bbox[3])
cv2.rectangle(frame_adjusted, (x, y), (x+w,y+h), (0,0,255), 4, 8, 0)
cv2.imshow('image',frame_adjusted)
cv2.waitKey(1)
