Question

在Raspberry Pi 3B上运行自定义语音助手程序时出现错误。此脚本由示例中的两个程序（assistant_library_demo.py和cloud_speech.py）组成。因此，脚本可以执行这些示例中的这两个功能。程序代码如下所示：

这是针对语音助手的，它结合了Google语音助手和Google Cloudspeech API的功能

    if language_code.startswith("en_"):

            "turn off the light",
            "blink the light",

        logging.info('Say "OK, Google" then speak, or press Ctrl+C to quit...')
    elif event.type == EventType.ON_CONVERSATION_TURN_STARTED:
        led.state = Led.ON  # Listening.
    elif event.type == EventType.ON_END_OF_UTTERANCE:
        led.state = Led.PULSE_QUICK  # Thinking.
    elif (
        event.type == EventType.ON_CONVERSATION_TURN_FINISHED
        or event.type == EventType.ON_CONVERSATION_TURN_TIMEOUT
        or event.type == EventType.ON_NO_RESPONSE

    credentials = auth_helpers.get_assistant_credentials()
    with Board() as board, Assistant(credentials) as assistant:
        for event in assistant.start():

这是错误文本的样子：从python shell运行草图时的错误文本：
