finetuning-scheduler
PyTorch Lightning extension that accelerates and enhances foundation model experimentation with flexible fine-tuning schedules.

About finetuning-scheduler
finetuning-scheduler is an open-source extension for PyTorch Lightning for defining fine-tuning schedules for foundation model experiments. It supports explicit or regex-based parameter selection, with implicit schedules for initial exploration and explicit schedules for tuning and behavioral experimentation.
It applies early-stopping criteria to each fine-tuning phase, restores the best per-phase checkpoint, and allows combining early-stopping with epoch-based phase transitions. It installs from PyPI using uv, with optional extras for examples, development and testing.
