numpy-assert-lint: A pre-commit hook to auto-fix NumPy assertions
viglovikov · x · 2026-08-02
Developer Vladimir Iglovikov shared a new tool called numpy-assert-lint, which has already been integrated into the image augmentation library Albumentations.
Running as a pre-commit hook or standalone CLI, the tool detects plain NumPy assertions (like assert np.allclose) that obscure useful failure diagnostics. Beyond reporting, it can safely rewrite these statements into numpy.testing helpers, providing detailed mismatch locations and values to accelerate debugging.
