我知道这是一个常见的问题，但我似乎不能自己解决它。我的图片在Tkinter上显示不出来。我做了调查，问题似乎出在垃圾收集上。我试过所有办法来阻止它，但似乎都不起作用。以下是我的完整代码:

以下是垃圾收集的解决方案，这些解决方案似乎与其他解决方案一起工作并没有解决问题:
- 将每个图像引用为变量。在我的情况下是不可能的(我不知道我一开始有多少)，而试图为一个图像做这个，它仍然没有显示。
- 保持标签的引用。Image = Image。这是我的代码，不起作用。li>使用类。ImagePersistent类也不能工作。
- 使用列表/字典/元组。自我。images不能工作，也不能把它放在self。l_widgets
- 使用全局变量。神仙不工作。我还尝试了globals().update({"immortals":{}})和immortals。更新({name:东西})。
所以我不知道。它仍然是网格的，当我不使用类时，它工作了!我觉得我什么都试过了。如果需要，我可以提供链接到图像(所有RGBA ping)。我知道它们确实存在，因为nbr_images的值变成了57。
我忘记把image作为一个属性放在配置部分。下面的代码是:
def create_a_label_with_an_image(self, name, filename,size=(None,None), config_args=None, grid_args=None, frame="main"):
global immortals
if grid_args is None:
grid_args = {}
if config_args is None:
config_args = {}
immortals[name] = ImagePersistent(filename, size).image
self.l_widgets[name] = (ttk.Label(self.frames[frame]), immortals[name])
self.l_widgets[name][0].config(**config_args, image=immortals[name])
self.l_widgets[name][0].image = immortals[name]
self.l_widgets[name][0].grid(**grid_args)
