如何解决当我运行代码时，图像不可见但是当我将鼠标悬停在任务栏中时，它有图像请帮帮我

当我运行代码时，我的图像没有显示出来。它没有给出任何错误，但是当我将鼠标悬停在我从任务栏创建的新页面中时，我可以看到图像闪烁一秒钟，然后它不会再次停留在主页上。怎么了？请帮帮我。

import pygame

class Ship:
  """A class to manage the ship."""
  
  def __init__(self,ai_game):
    """Initialize the ship and set its starting position."""
    self.screen = ai_game.screen
    self.screen_rect = ai_game.screen.get_rect()
    
    #Load the ship image and get its rect.
    self.image = pygame.image.load('images/ship.bmp')
    self.rect = self.image.get_rect
    
    #Start each new ship at the bottom center of the screen.
    self.rect.midbottom = self.screen_rect.midbottom
    
  def blitme(self):
    """Draw the ship at it's current location."""
    self.screen.blit(self.image,self.rect)

我已经检查了我的目录和文件，它们位于正确的位置，一切对我来说似乎都是正确的，但代码仍然无法正常工作。

我的目录看起来像;
