NameError: name 'platform' is not defined

这个错误通常发生在尝试在没有导入 `platform` 模块的情况下使用它的函数或变量时。请确保您在代码中导入了 `platform` 模块，例如：

import platform

# 使用 platform 模块的函数或变量

如果您已经导入了 `platform` 模块，则可能是因为在导入模块之前尝试使用了 `platform` 模块的函数或变量。请确保您在使用 `platform` 模块之前先导入它。

NameError: name 'GPIO' isn't defined

It seems that you are encountering a NameError with the 'GPIO' module. This error typically occurs when the 'GPIO' module has not been imported or is not available in your current environment.

To resolve this issue, you need to make sure that you have the 'GPIO' module installed and imported correctly. The 'GPIO' module is commonly used for controlling hardware peripherals, such as the Raspberry Pi's General Purpose Input/Output (GPIO) pins.

If you are working with the Raspberry Pi, you can install the RPi.GPIO library by running the following command:

pip install RPi.GPIO

After installing the library, you can import it in your Python script with the following line:

import RPi.GPIO as GPIO

Make sure that your script is running in an environment where the 'RPi.GPIO' library is accessible. If you are running your script outside of a Raspberry Pi, you may encounter this error because the library is specific to that platform.

If you have already installed the 'RPi.GPIO' library and are still encountering this error, please provide more details about your setup and the specific code you are running so that I can assist you further.

这个错误提示意味着程序中使用了`pd`这个名称但是该名称没有被定义。通常情况下，`pd`指的是Python中的pandas库，因此可能是你没有导入pandas库导致的。你可以在程序开头加上以下代码导入pandas库：

import pandas as pd

如果你已经导入了pandas库，那么可能是你的安装存在问题，你可以尝试重新安装pandas库。
