Introduction
|
||
|
------------
|
||
|
|
||
|
By design asyncio `does not allow <https://bugs.python.org/issue22239>`_
|
||
|
its event loop to be nested. This presents a practical problem:
|
||
|
When in an environment where 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 module patches asyncio to allow nested use of ``asyncio.run`` and
|
||
|
``loop.run_until_complete``.
|
||
|
|
||
|
Installation
|
||
|
------------
|
||
|
|
||
|
.. code-block::
|
||
|
|
||
|
pip3 install nest_asyncio
|
||
|
|
||
|
Python 3.5 or higher is required.
|
||
|
|
||
|
Usage
|
||
|
-----
|
||
|
|
||
|
.. code-block:: python
|
||
|
|
||
|
import nest_asyncio
|
||
|
nest_asyncio.apply()
|
||
|
|
||
|
Optionally the specific loop that needs patching can be given
|
||
|
as argument to ``apply``, otherwise the current event loop is used.
|
||
|
An event loop can be patched whether it is already running
|
||
|
or not. Only event loops from asyncio can be patched;
|
||
|
Loops from other projects, such as uvloop or quamash,
|
||
|
generally can't be patched.
