python 任务计时器 apscheduler.schedulers

crontab 真的不好用

import pandas as pd
import subprocess
import os
import time
from datetime import datetime
from apscheduler.schedulers.blocking import BlockingScheduler
import logging
python_path = '/home/game/anaconda3/bin/python'



def train_and_restart():

    logging.error('start train model:{}'.format(datetime.now()))
    os.system('/bin/bash /home/game/glory_deepfm1/AP/rec1/gcs_data.sh')

    #logging.error('update model weight to cloud storage:{}'.format(datetime.now()))
    #os.system('{} update_weight.py>>train_log.txt'.format(python_path))


if __name__ == '__main__':
    hours = 2
    scheduler = BlockingScheduler()

    scheduler.add_job( train_and_restart, 'cron',hour= '*/2')
#    scheduler.add_job(train_and_restart, 'interval', hours = hours, next_run_time = datetime.now() + pd.Timedelta(hours = 0))
    scheduler.start()
