# pytest_networkx
Reproduce the error
```
git clone https://github.com/woutdenolf/pytest_networkx.git
cd pytest_networkx
python setup.py build sdist
pip install dist/myproject-1.0.0.tar.gz[test]
pytest --pyargs myproject -W error
```
In python 3.9 there seem to be two entry points for `networkx.backends`.
This does not happen for python 3.8, 3.10 or 3.11.
