Using jupyter notebook causes RuntimeError: asyncio.run() cannot be called from a running event loop

[tyePhDCandy]

fact and question

The code works when I call the .py file using python test.py on command line. It does not work when I executed the code inside the cell of jupyter notebook.

How do i modify my code such that it would work in jupyter notebook?

Here's my code.

import os
import discord
import asyncio
from dotenv import load_dotenv

load_dotenv()
TOKEN = os.getenv('DISCORD_TOKEN')
print(TOKEN)

intents = discord.Intents.default()
intents.message_content = True

client = discord.Client(intents=intents,proxy='http://127.0.0.1:7890')

@client.event
async def on_ready():
    print(f'We have logged in as {client.user}')

@client.event
async def on_message(message):
    if message.author == client.user:
        return

    if message.content.startswith('$hello'):
        await message.channel.send('Hello!')

client.run(TOKEN)

Here's my errors

RuntimeError                              Traceback (most recent call last)

     31     if message.content.startswith('$hello'):

RuntimeError: asyncio.run() cannot be called from a running event loop

My investigation

I know RuntimeError: asyncio.run() cannot be called from a running event loop is resulted from the use of jupyter notebook executing the code.

Referencing this webpage asyncio-run-cannot-be-called-from-a-running-event-loop-when-using-jupyter, I concluded:

The asyncio.run() documentation says:

This function cannot be called when another asyncio event loop is running in the same thread.`

jupyter (IPython ≥ 7.0) is already running an event loop:

You can now use async/await at the top level in the IPython terminal and in the notebook, it should — in most of the cases — “just work”. Update IPython to version 7+, IPykernel to version 5+, and you’re off to the races.

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

[2br-2b]

Could asyncio.create_task(client.run(TOKEN)) work? I believe that will run it in the current event loop.

It would either be that or one of these solutions:

loop = asyncio.get_event_loop()
loop.run_until_complete(client.run(TOKEN))
loop.close()

client.run is not a coroutine so won't work but client.start might
