Description

Native OCaml bindings to libxgboost (>=3.0). Three-layer FFI: the upstream stable C ABI, statically generated ctypes stubs, and a high-level GC-aware OCaml API. Supports dense and sparse DMatrix construction (Bigarray, zero-copy), training, prediction, JSON config, and external-memory streaming via a callback iterator.

The native libxgboost dependency is satisfied in one of two ways, decided at build time: a system libxgboost >= 3.0 discovered through pkg-config (installed through conf-libxgboost where the platform packages it), or, failing that, a vendored copy of XGBoost built from source with CMake and linked statically (needs no network).

Build status

Results of building xgboost with each compiler on check.ci.ocaml.org, run of against opam-repository 7cdc698. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
