我尝试使用库 cv2 来更改图片。在调试模式下，我在函数cv2.namedWindow中发现了该问题：
def run(self):
name_of_window = 'Test_version'
image_cv2 = cv2.imread('external_data/probe.jpg')
cv2.namedWindow(name_of_window, cv2.WINDOW_NORMAL)
cv2.imshow(name_of_window, image_cv2)
cv2.waitKey(0)
cv2.destroyAllWindows()
cv2.namedWindow 出现警告并且程序停止后。如果有人提供建议，我会很高兴。
当我调用 os.environ 时，出现以下内容：
