PyPilot (CLI & Python Package)

⭐ Enjoying PyPilot? If it saved you from a broken environment, please star it on GitHub. It's free and it helps other Python developers find it.

PyPilot is a deterministic Python environment doctor, dependency solver, and toolchain manager. Powered by a high-speed compiled Rust engine, PyPilot calculates dependency intersections directly from PyPI wheel metadata, resolves hardware and CUDA build compatibility, and sets up working virtual environments without external AI or API keys.

⚡ High-Speed Native Rust Architecture

PyPilot combines the ease of installation via pip with the raw execution speed and low memory footprint of compiled Rust:

• Instant startup: Binary execution starts in single-digit milliseconds.
• Zero Python overhead: CLI commands delegate directly to the native pypilot binary.
• Automatic platform management: Transparently downloads and caches the verified native engine matching your operating system (Linux x86_64, macOS Apple Silicon / Intel, Windows x64), or respects a system-installed Rust binary on your $PATH.

📥 Installation

Install via pip:

pip install pypilot-cli

Or install as an isolated global tool with uv:

uv tool install pypilot-cli

Or via pipx:

pipx install pypilot-cli

📖 CLI Reference & Commands

PyPilot provides a complete suite of environment doctor and bootstrap tools:

1. pypilot doctor

Analyzes your current workspace, virtual environment, and dependency manifests (requirements.txt, pyproject.toml, environment.yml). Displays a read-only health check without modifying any files.

pypilot doctor
# Target a specific workspace folder:
pypilot doctor --path /path/to/project

2. pypilot setup

Bootstraps a deterministic virtual environment. Automatically detects existing system tools:

• Uses system uv if present on $PATH.
• Supports pip-compatible mode (uv venv + uv pip) to accelerate installations without forcing a pyproject.toml migration.
• Falls back cleanly to standard python -m venv + pip if uv is not installed.

3. pypilot check <package>

Verifies whether a specific package and its wheels support your project's current Python interpreter version and operating system.

pypilot check mediapipe
pypilot check torch
pypilot check tensorflow

4. pypilot install <package>

Installs a package into your virtual environment and records it in your manifest (requirements.txt or pyproject.toml), preserving version constraints.

pypilot install requests
pypilot install numpy

5. pypilot fix python

Recomputes dependency version intersection and rebuilds the virtual environment on a Python version supported by all dependencies.

pypilot fix python

6. pypilot fix cuda

Scans system NVIDIA driver version and CUDA runtime, then re-pins PyTorch or TensorFlow wheels to the exact hardware-matched CUDA build.

pypilot fix cuda

7. pypilot update-data

Forces an immediate update of bundled hardware driver, CUDA compatibility matrices, and package wheel metadata.

8. pypilot migrate-conda

Translates legacy Anaconda / Miniconda environment.yml configuration files into a standard modern pyproject.toml.

pypilot migrate-conda

9. pypilot lsp

Runs PyPilot as a Language Server Protocol (LSP) server over stdio. Used natively by editor extensions (Zed and VS Code) for live import diagnostics and automated environment actions.

🐍 Python Programmatic API

PyPilot can also be imported and used directly inside Python code:

import pypilot

# Run any PyPilot command programmatically
result = pypilot.run(["doctor"], capture_output=True)
print(result.stdout)

# Locate or ensure native engine is available
bin_path = pypilot.ensure_binary()
print(f"Native engine located at: {bin_path}")

⚙️ Configuration

PyPilot respects workspace settings in .pypilot.toml or your editor configuration:

• package_manager: "auto" (default), "uv", "uv-pip", or "pip".
• notifications: "all", "problems-only", or "off".

💙 Support the project

PyPilot is free and open source, built and maintained in spare time. If it helps you:

• ⭐ Star it on GitHub: it's the easiest way to show support.
• 🐛 Report a bug or request a feature: reproducible environment problems are especially welcome.
