## Summary - Add `create_import_stub()` helper to `embeddings/utils.py` for handling optional dependencies - Fix MLX doctest collection failures by using import stubs in `gte_mlx_model.py` - Module now imports successfully for doctest collection even when MLX is not installed ## Changes - **New utility function**: `create_import_stub()` creates placeholder objects that allow class inheritance but raise helpful errors when used - **Updated MLX model**: Uses import stubs instead of direct imports that fail immediately - **Graceful degradation**: Clear error messages when MLX functionality is accessed without MLX installed ## Test Results - ✅ `pytest --doctest-modules python/lancedb` now passes (with and without MLX installed) - ✅ All existing tests continue to pass - ✅ MLX functionality works normally when MLX is installed - ✅ Helpful error messages when MLX functionality is used without MLX installed Fixes #2538 --------- Co-authored-by: Will Jones <willjones127@gmail.com>

Preview Releases
Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
