如何使用babel翻译Python GUI应用程序?

我将非常感谢您的帮助:

我正在尝试本地化我的GUI应用程序,比如说白俄罗斯语言。我已经提取了一个标签字符串并编译了一个.mo文件。第一次尝试时,我只想在加载应用程序后,打开默认翻译了上述字符串的应用程序。然而,由于某种原因,翻译似乎被跳过了。 你能帮我找出错误在哪里吗?:

messages.mo目录:C:\Users\MyUser\PycharmProjects\PersFin\translations\be\LC_messages

我要翻译的标签字符串:

my_transactions_frame = tkinter.LabelFrame(frame, text=_("**My Transactions**"),
    font=('Helvetica', 12, 'bold'), fg='dodger blue')

翻译代码(主程序部分之前的开始块):

translations = Translations.load(r'C:\Users\MyUser\PycharmProjects\PersFin\translations\be\LC_MESSAGES', locales=[Locale('be')])
os.environ['LANG'] = 'be'
translations.install()

这就是.po文件所包含的内容(.mo文件是从中编译的):

我尝试过:重新编译.mo文件,重新启动IDE,检查目的地/目录,gettext。。。
