可能导致我的 Python GUI 程序中的“类型对象”MainFrame“没有属性”MainTemp_meter1“错误的原因

问：

我正在编写一个代码来更新我的温度传感器和一个计时器，并将其转换为我的 Gui 上的仪表。问题出在更新程序代码中的某个地方，因为这是创建错误代码的唯一代码，更准确地说，这个错误代码：“类型对象'MainFrame'没有属性'MainTemp_meter1'”。

我尝试了不同的代码和代码样式来使更新程序正常工作，但到目前为止都没有工作。现在有了最新的，我至少可以保持 Gui 运行，但我还不能更新任何内容。 [使用的进口]

                    # Update temperature reading 
                    temp_reading_top = sensors.sensor.read_temperature()
                    humid_reading_top = sensors.sensor.read_humidity()
                    MainFrame.MainTemp_meter1.set(temp_reading_top)
                    DiagFrame.temp_meter1.set(temp_reading_top)
                    DiagFrame.humid_meter1.set(humid_reading_top)

                    # Update current date and time
                    date = dt.datetime.now()
                    MainFrame.label_timedate.configure(text=f"{date:%A, %B %d, %Y, %H:%M}")

                    # Update timer label 
                    timer_reading = self.timer_frame.timer10.read_current()
                    formatted_time = timers.Timer.format_time(timer_reading)  # Call format_time from timers.Timer
                    self.timer_frame.time_var.set(formatted_time)

                    print('updated')

                    # Update the GUI
                    MainFrame.update_idletasks()
                    DiagFrame.update_idletasks()
                    TimerFrame.update_idletasks()
                    # Delay for a certain period (e.g., 1 second)
                    time.sleep(1)
            except Exception as e:
                print("Update error:", str(e))
    # Create and start a separate thread for the update loop
    update_thread = threading.Thread(target=update_readings, daemon=True)
    update_thread.start()

到目前为止，我一直希望更新程序在线并使我的代码正常工作，以便我可以随心所欲地监视不同的情况。使用的一些例子是测量内部或外部的温度以及湿度，并将其放在日志中，这样我就可以看到凌晨 3 点左右的温度。
