学習に時間がかかるAIモデルの学習時に，学習の進捗を通知したいという動機でSlack Incoming Webhookの使用を考えた．
上のURLからSlackチャネルのWebhookURLを取得して，指定する．

import socket
import requests
from datetime import datetime


class slack_channel():
    def __init__(self, url, channel):
        self.url = url
        self.channel = channel
        
        self.hostname = socket.gethostname()
        self.icon_emoji = ":desktop_computer:"
        self.current_time = datetime.now().strftime("%Y/%m/%d-%H時%M分")
        
    def send(self, title, message):
        payload = {
            "channel": self.channel,
            "username": self.hostname,
            "icon_emoji": self.icon_emoji,
            "attachments": [
                {
                    "fallback": "Fallback text for older clients",
                    "pretext": None,
                    "color": "#36a64f",
                    "title": title,
                    "text": message,
                    "footer": self.current_time,            
                }
            ]
        }
        response = requests.post(self.url, json=payload)
        # エラーが出たらプリント
        if response.status_code == 200:
            pass
        else:
            print(f"エラーが発生しました: {response.status_code}")

slack = slack_channel(url='https://yourwebhookurl', channel='#your_channel_or_yourpersonalID')
slack.send(title='TEST SEND', message='this is test sending')

• 以下のような感じで通知できます．
