I am managing a project with uv. My project includes - src - app.py - constants.py - notebooks - testing.ipynb - pyproject.toml  where my pyproject.toml is [project] name = "benchmark-extractor" version = "0.1.0" description = "Add your description here" readme = "README.md" requires-python = ">=3.13" dependencies = [ "anthropic>=0.42.0", "ipykernel>=6.29.5", "markitdown>=0.0.1a3", "pandera>=0.22.1", "tabula-py>=2.10.0", ]  I want to import app.py and constants.py into notebooks/testing.ipynb, for experimentation purposes. When I do this naively, e.g. import src.app, I get a ModuleNotFoundError. I believe I could approach this using uv pip install -e . (e.g. Sibling package imports) but when I try that, I get ERROR: Package 'benchmark-extractor' requires a different Python: 3.11.3 not in '>=3.13'.
Add this section into pyproject.toml: [tool.uv] package = true  Then run uv sync Now you should be able to import app in notebooks/testing https://docs.astral.sh/uv/concepts/projects/config/#project-packaging
