LeanDojo: Machine Learning for Theorem Proving in Lean

LeanDojo: Machine Learning for Theorem Proving in Lean

LeanDojo is a Python library for learning–based theorem provers in Lean, providing two main features:

• Extracting data (proof states, tactics, premises, etc.) from Lean repos.
• Interacting with Lean programmatically.

LeanDojo's current version is compatible with Lean 4 v4.3.0-rc2 or later. We strongly suggest using the current version. However, you may use the legacy branch if you want to work with earlier versions (including Lean 3).
