大家晚上好,我正在尝试创建互联网机器人,我在将我的脚本从python 3.4迁移到3.5或3.6+时遇到了问题.它使用asyncio并且在3.4 python上运行良好但是当我用python3.5 +启动时我得到了错误:RuntimeError: Cannot run the event loop while another loop is running

这是代码方案:

import multiprocessing as mp
import asyncio
import concurrent.futures
import aiohttp

def create_proccesses(separate_loop_creator, coro):
    proccesses = []
    for n in range(2):
        proc = mp.Process(target=separate_loop_creator, args=(coro,))
        proc.start()
        proccesses.append(proc)
    for p in proccesses:
        p.join()

def separate_loop_creator(coro):
    sep_loop = asyncio.new_event_loop()
    asyncio.set_event_loop(sep_loop)
    tasks = [asyncio.async(coro(sep_loop)) for _ in range(100)]
    try:
        sep_loop.run_until_complete(asyncio.wait(tasks))
        sep_loop.close()
    except Exception as err:
        print(err)
        for task in tasks:
            task.cancel()
        sep_loop.close()


@asyncio.coroutine
def manager(exe, loop):
