我有一个在 Raspberry Pi 3B+ 上以 python 运行的 Discord 机器人。该程序的目的是通过按下物理按钮将实验室状态发送到我们的服务器。我注意到程序本身并不总是想要合作，并且一直在使用 100% 的内核。我相信硬件仍然健康，唯一正在运行的就是操作系统本身。每次我检查时，htop 都会读取单个程序正在使用 98-101% 的内核。

from os import system
from datetime import date
from time import sleep

from gpiozero import LED, Button
import discord
from discord.ext import commands

import asyncio

# Pull in server token and channel ID
with open('/home/pi/EVC-Discord-Bot/token.txt', 'r') as f:
    TOKEN = f.read()
with open('/home/pi/EVC-Discord-Bot/channel.txt', 'r') as f:
    CHANNEL = f.read()

# Define bot properties
description = '''EVC Lab Bot'''
bot = commands.Bot(command_prefix='!', description=description)

# Define client
client = discord.Client()

# Button and LED GPIO pins
openbutton=Button(17)
pendingbutton=Button(27)
closedbutton=Button(22)
###
openlight=LED(4)
pendinglight=LED(23)
closedlight=LED(24)

# Saved Messages
openmessage=':green_circle: :radio_button: :radio_button: OPEN :green_circle: :radio_button: :radio_button:'
pendingmessage=':radio_button: :yellow_circle: :radio_button: PENDING :radio_button: :yellow_circle: :radio_button:'
closedmessage=':radio_button: :radio_button: :red_circle: CLOSED :radio_button: :radio_button: :red_circle:'

    # Define desired channel
    channel = bot.get_channel(int(CHANNEL))
    # Terminal print channel and status

        await channel.send(closedmessage)
    # Terminal print "completed"
    print('Finished.')

    # Tell me on_ready() def has started

如果没有按下按钮，你on_ready基本上是

async def on_ready():
    print('On ready!')
    while True:
        pass

这当然会占用 100% 的 CPU！
