python - 图片 "pyimage5"不存在添加5行代码后出错

Question

我试图从另一个类的输入框中调用一个字符串到一个公共(public)变量。调用 Var 接缝的代码工作正常，但出现错误“图像“pyimage5”不存在”，这是我的第二类罪过，我添加了新的代码行。之前一切都很有趣。

我添加的代码行:

class StartPage(tk.Frame):

     def __init__(self, parent, controller):
         tk.Frame.__init__(self,parent)

class PageOne(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent,bg=Gray_Back_Page_1)

到

class StartPage(tk.Frame):

     def __init__(self, parent, controller):
         super(StartPage,self).__init__()

class PageOne(tk.Frame):

    def __init__(self, parent, controller):
        super(PageOne,self).__init__(parent,bg=Gray_Back_Page_1)

并在类外部添加以下代码

StartPage_object = StartPage(tk.Frame, SeaofBTCapp) 
USER = StartPage_object.Username_Text.get() 
PASSWORD = StartPage_object.Password_Text.get()

图像代码 Var = Image.open(Image_File +"\File_Name.png") 接缝在我的起始页中工作，但在我的第一页中出现错误

请参阅下面的完整代码:

desktop = os.path.expanduser("~\Desktop")
Image_File = os.path.expanduser("~\Desktop\file")

        for F in (StartPage, PageOne):

        vlabel.image = photo
        vlabel.place (x=-1,y=-5,relwidth=1, relheight=1)

错误行:

对我来说，问题出在 Spyder 而不是代码。我更换为 Jupyter Notebook，它按预期工作
