Steps to reproduce
Tested inside WSL2 on Windows 11 version 23H2.
Delete all existing poetry-cookicutter Docker containers and images.
Clone the repo to a local folder:
git clone git@github.com:radix-ai/poetry-cookiecutter.gitOpen it with VSCode:
code .Run VSCode command: Dev Containers: Rebuild Without Cache and Reopen in Container.
The poetry-cookiecutter dev container builds and opens.
Once completely initialized, open VSCode's bash terminal: Terminal: Create New Terminal.
Scaffold a new Python 3.12 package project using cruft:
cruft create -f https://github.com/radix-ai/poetry-cookiecutterChoose the following cookiecutter values. Here reported in the generated .cruft.json:
{
"template": "https://github.com/radix-ai/poetry-cookiecutter",
"commit": "8ab7ee0accff3b9cb0e470bfc925858fc04d1e97",

"__project_name_snake_case": "my_package",
"_template": "https://github.com/radix-ai/poetry-cookiecutter"
}
},
"directory": null
}Exit the dev container and close VSCode.
Copy the scaffolded project to another local folder:
cd ..
cp -r poetry-cookiecutter/my-package ./Navigate to the scaffolded project folder and open it with VSCode:
cd my-package/
code .Build the project's dev container: run VSCode command: Dev Containers: Rebuild Without Cache and Reopen in Container.
Once completely initialized, open VSCode's bash terminal: Terminal: Create New Terminal.
Add Streamlit as a dependency:
poetry add streamlitCreate a Python file that imports streamlit:
In src/my_package/app.py:
"""A Streamlit app."""
import streamlit as stInit a git repo:
git initRun code linting:
poe lintRun tests:
poe testHi, @vanolucas, thanks for submitting this issue! It looks like it's a known issue on Streamlit side in combination with the strict configuration of pytest which is enabled with development_environment=strict.
I see that there's a fix merged already so I expect it to no longer be an issue in the next streamlit release. As a temporary workaround, I'd recommend switching to the simple development environment or remove the line filterwarnings = ["error", "ignore::DeprecationWarning"] in the pyproject.toml which causes pytest to fail on warnings.
