Python监控服务器显卡使用情况程序

说明：该程序能够实时监控服务器的显卡运行情况，当达到设定的条件时，会发送邮件进行通知。建议打开微信邮件助手功能，可以实时收到通知信息。
改代码需要发送邮件部分，按要求写入自己的信息即可。

import pynvml
import time
import sys
import smtplib
from email.mime.text import MIMEText
from email.header import Header
pynvml.nvmlInit()

def send_msg(target_add, msg):
  # 发信方的信息：发信邮箱，QQ邮箱授权码
  from_addr = ''
  password = ''
  # 收信方邮箱
  # 发信服务器
  smtp_server = 'smtp.163.com'
  # server = smtplib.SMTP_SSL()
  server=smtplib.SMTP_SSL('smtp.163.com')
  server.connect(smtp_server,465)
  server.login(from_addr, password)
  # 发送邮件
  message = MIMEText(msg, 'plain', 'utf-8')
  server.sendmail(from_addr, target_add, message.as_string())
  # 关闭服务器
  server.quit()
