duckdb-mlpack 0.0.3: macOS binaries, unit tests, more outputs

Mon, 03 Nov 2025 10:17:00 CDT

A littler two weeks a short post announced the duckdb-mlpack as ‘ML quacks’: combining the powerful C++ machine learning library mlpack with the amazing analytical database engine duckdb. About a week ago another short post covered first extensions. We actually followed-up with release 0.0.3 days later, and never posted about it so this short note catches up.

In release 0.0.3, we provide macOS binaries: following a known issue with one of the components, we apply a simple patch to enable the build. Next up are wasm and windows, if you know your way around these platforms please get in touch. Release 0.0.3 also added first unit tests, serializes the coefficients from the (regularized) linear regression into the output table.

See see two previous posts linked above for details and background, the repo for code, issues and more, and the extension page for more about this duckdb community extension.
