PEP 561 type stubs for joblib, providing type hints for joblib's core modules including Parallel, delayed, Memory, and dump/load. Current version is 1.5.3.1.20260117, compatible with joblib>=1.5.3.2 (cpython-only). Updated to track joblib releases, with occasional fixes for type accuracy.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Parallel
✓ from joblib_stubs import Parallel
✗ from joblib import Parallel
delayed
✓ from joblib_stubs import delayed
✗ from joblib import delayed
Memory
✓ from joblib_stubs import Memory
✗ from joblib import Memory

Install joblib-stubs and use joblib normally; mypy or pyright will use the stubs for type checking.

from joblib import Parallel, delayed results = Parallel(n_jobs=2)(delayed(lambda x: x**2)(i) for i in range(10)) print(results)

Known issues
gotchajoblib-stubs is a stub-only package. It does not contain joblib itself. You must install `joblib` separately.
fix
Install both: `pip install joblib joblib-stubs`.
affects: all
gotchaThe stubs are tied to specific joblib versions. Ensure the joblib-stubs version aligns with your installed joblib version (e.g., joblib-stubs 1.5.3.x expects joblib ~=1.5.3).
fix
Check compatibility: `pip install joblib-stubs==$(python -c 'import joblib; print(joblib.__version__)')` or use constraints.
affects: >=1.5.0
gotchaSome stubs (e.g., `Memory`) may have incomplete type signatures. For instance, `joblib.Memory.__init__` might not perfectly reflect runtime default parameters.
fix
If you encounter type errors for advanced usage, consider adding inline `# type: ignore[arg-type]` and report issue to GitHub.
