Hummingbird

Hummingbird is a Microsoft-maintained library that converts trained traditional ML models (scikit-learn, LightGBM, XGBoost, PyTorch, ONNX) into tensor computations (PyTorch, TorchScript, ONNX, TVM). It enables GPU acceleration and scaling for legacy models with minimal code changes. Current version 0.4.12, release cadence is irregular (~quarterly). Requires Python >=3.8.
