アナコンダスパイダーは、同時実行プロセスのエラー解決を使用しています。RuntimeError: このイベントループは既に実行されています

今朝、anacondaのspyderでコンカレントコードを書いているときにエラーに遭遇しました。
コードは以下の通りです。

import asyncio

async def coroutine():
    print("hey")
    await asyncio.sleep(1)

asyncio.get_event_loop().run_until_complete(coroutine())

エラーは以下のように報告されます。

Didn't fix the problem.
Solution 1
No need for
spyder
, use
pychram
or terminal to run the program directly, you don't have this problem.
Solution 2
Install
nest_asyncio
:
pip install nest_asyncio

Start the code with.
