The "Event loop is closed" error typically occurs when trying to run asynchronous code after the event loop has been terminated. This can happen if the event loop is not properly managed or if it is closed prematurely by the application or framework you are using.
To address this issue, you can ensure that the event loop is correctly initialized and managed. Here are some steps you can take:
-
Check Event Loop Initialization: Make sure that the event loop is properly initialized before running any asynchronous tasks. You can create a new event loop and set it as the current event loop using the following code:
import asyncio # Create a new event loop loop = asyncio.new_event_loop() # Set the event loop as the current event loop asyncio.set_event_loop(loop) -
Use
asyncio.run(): If you are running a main asynchronous function, consider usingasyncio.run()to ensure that the event loop is properly managed. This function handles the creation and closure of the event loop automatically. -
Avoid Nested Event Loops: If you are working in an environment like Jupyter notebooks, where an event loop might already be running, you can use
nest_asyncio.apply()to allow nested event loops:import nest_asyncio nest_asyncio.apply() -
Ensure Proper Closure: Make sure that the event loop is not being closed prematurely by any part of your code or by external libraries.
By following these steps, you should be able to manage the event loop lifecycle more effectively and avoid the "Event loop is closed" error.
