【Jupyter】异步RuntimeError: asyncio.run() cannot be called from a running event loop

问题：在jupyter notebook中使用asyncio.run()时发生如上标题报错，没错就是这个

 官方文档：This function cannot be called when another asyncio event loop is running in the same thread.

百度翻译：当另一个异步事件循环在同一线程中运行时，无法调用此函数

大致就是jupyter 已经运行了loop，无需自己激活，采用上文中的await()调用即可

In jupyter

async def main():
        print(1)
await main()

In plain Python (≥3.7)

import asyncio
async def main():
    print(1)
asyncio.run(main())
