nest-asyncio

Introduction

By design asyncio does not allow its event loop to be nested. This presents a practical problem: When in an environment were the event loop is already running it’s impossible to run tasks and wait for the result. Trying to do so will give the error “RuntimeError: This event loop is already running”.

The issue pops up in various environments, such as web servers, GUI applications and in Jupyter notebooks.

This package will patch asyncio to allow nested use of asyncio.run and loop.run_until_complete.

Installation

pip3 install nest_asyncio

Python 3.5 or higher is required.

Usage

import nest_asyncio
nest_asyncio.apply()
