name: python-environment description: Python environment setup with uv, shared utilities, and script structure guidelines.

Python Environment

Always use uv run. Never search for Python or use venv directly.

uv run uses the venv from the nearest pyproject.toml up the directory tree. Run scripts from the project root:

Copycd /path/to/project  # directory with pyproject.toml
uv run python experiments/experiment_X/fit/run_fit.py

Shared Utilities

shared-utils is a project dependency. Import directly:

Copyfrom shared_utils import compile_model, fit_model, check_convergence, ...

Read the package source at /workspace/shared_utils/ for API details.

Script Structure

Write small, focused scripts - not monolithic files. Separate concerns:

Copyexperiment_X/
  fit/
    run_fit.py        # Main entry point
    diagnostics.py    # Convergence checks
    plots.py          # Visualization

Each script should:

• Do one thing well
• Be runnable independently via uv run python script.py
• Import shared logic from shared_utils
