Неустранимая ошибка Python: ошибка сегментации при запуске моей собственной программы Voice Assistant

У меня ошибка при запуске моей пользовательской программы голосового помощника на Raspberry Pi 3B. Этот скрипт сделан из двух программ из примеров (assistant_library_demo.py и cloud_speech.py). Следовательно, скрипт выполняет обе функции из этих примеров. Вот как выглядит код программы:

Это для голосового помощника, который сочетает в себе функции голосового помощника Google и API Google Cloudspeech 

import argparse
import locale
import logging
import RPi.GPIO as GPIO
from gpiozero import Servo
import signal
import sys
from google.assistant.library.event import EventType
from aiy.assistant import auth_helpers
from aiy.assistant.library import Assistant
from aiy.board import Board, Led
from aiy.cloudspeech import CloudSpeechClient
import aiy.voice.tts


def get_hints(language_code):
    if language_code.startswith("en_"):
        return (
            "turn on the light",
            "turn off the light",
            "blink the light",
            "goodbye",
            "repeat after me",
            "lights on",
            "lights off",
            "minimum",
            "middle",
            "maximum",
        )
    return None


def locale_language():
    language, _ = locale.getdefaultlocale()
    return language


def process_event(led, event):
    logging.basicConfig(level=logging.INFO)
    GPIO.setmode(GPIO.BCM)
    GPIO.setwarnings(False)
    GPIO.setup(24, GPIO.OUT)
    servo = Servo(6)
    parser = argparse.ArgumentParser(description="Assistant service example.")
    parser.add_argument("--language", default=locale_language())
    args = parser.parse_args()
    logging.info("Initializing for language %s...", args.language)
    hints = get_hints(args.language)
    client = CloudSpeechClient()
    logging.info(event)
    text = client.recognize(language_code=args.language, hint_phrases=hints)
    if "lights on" in text:
        GPIO.output(24, GPIO.HIGH)
    elif "lights off" in text:
        GPIO.output(24, GPIO.LOW)
    elif "maximum" in text:
        servo.max()
    elif "minimum" in text:
        servo.min()
    elif "middle" in text:
        servo.mid()
    if event.type == EventType.ON_START_FINISHED:
        led.state = Led.BEACON_DARK  # Ready.
        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
    ):
        led.state = Led.BEACON_DARK
    elif (
        event.type == EventType.ON_ASSISTANT_ERROR
        and event.args
        and event.args["is_fatal"]
    ):
        main()


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


if name == "main":
    main()

Спасибо всем за вашу помощь, я исправил проблему, переписав весь код с помощью различных демонстраций Google
