我在python中使用opencv2和代碼import cv2

cv2.namedWindow("output", cv2.WINDOW_NORMAL)

cv2.imshow("output",im)

cv2.resizeWindow('output', 400,400)

cv2.waitKey(0)

cv2.destroyAllWindows()

我的錯誤是QObject::moveToThread: Current thread (0x1d2c9cf0) is not the object's thread (0x1d347b20).

Cannot move to target thread (0x1d2c9cf0)

我調試發現它發生在我使用cv2.waitKey(0)時。我該怎么修？謝謝

更新：我正在使用3.3.0.0。如果我使用舊版本，我有錯誤

OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvDestroyAllWindows, file /io/opencv/modules/highgui/src/window.cpp, line 577
