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

問題：在jupyter notebook中使用asyncio.run()時發生如上標題報錯，沒錯就是這個

 

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

百度翻譯：當另一個異步事件循環在同一線程中運行時，無法調用此函數

 

大致就是jupyter 已經運行了loop，無需自己激活，采用上文中的await()調用即可

In jupyter

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

In plain Python (≥3.7)

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