Environment:
Python 3.10.11
Flask==2.2.2
I run my Flask backend code in docker container, with BASE Image:
FROM pytorch/pytorch:2.0.1-cuda11.7-cudnn8-runtime
But when I run the pytest with version pytest 7.4.2,
pip install pytest
pytest
it raised an Error, with logs:

My codes works well when I directly run it with python run.py
run.py shown below
from daat import app
app.run(host='0.0.0.0')
I guess it should be the pytest versions issue, because it used to work well without changing any related code, and I use pip install pytest without defined a specific version.
And my backend runs well without pytest.
I had the same problem. It is because Werkzeug 3.0.0 was released and Flask doesn't specify the dependency correctly (requirements says Werkzeug>=2.2.0). This is why, Werkzeug 3.0.0 is still installed and Flask 2.2.2 isn't made for Werkzeug 3.0.0.
Solution: Just set a fix version for Werkzeug such as Werkzeug==2.2.2 in your requirements.txt and it should work.
