It wraps the complete FastJet functionality and integrates tightly with Awkward Array and Vector, allowing you to work with columnar particle data efficiently. The package supports three execution modes: vectorized, out-of-core vectorized using Dask for large datasets, and non-vectorized clustering.\n\nYou supply particle data in any coordinate system and specify a clustering algorithm; FastJet groups particles according to that algorithm's rules. The Awkward Array integration means you can pass and receive nested, ragged arrays of particles directly, making it natural to cluster multiple events in a single call. It's designed for high-energy physics workflows where particle clustering is a standard preprocessing step.","worth_installing":"Yes, if you work in high-energy physics and need to cluster particles. The package is actively maintained, has no known vulnerabilities, and offers pre-built wheels for common platforms. Medium install friction applies only to source builds; binary wheels sidestep most C++ dependencies. The BSD-3-Clause license is permissive. Install from PyPI wheels for fastest setup."},"id":"fastjet","links":{"html":"https://skillfed.io/packages/fastjet","md":"https://skillfed.io/packages/fastjet.md","pypi":"https://pypi.org/project/fastjet/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-28","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"fastjet","python_support":"supports_current","summary":null},"popularity":{"monthly_downloads":372459,"position":7161,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.5.1.4"}
