Description
This PR adds minimal support for the unsloth library without making it a required dependency of Oumi. The idea is to let users load models and tokenizers through Unsloth’s API if it’s available, without changing the trainer abstraction or adding a new TrainerType. Since Unsloth patches
transformersandtrlunder the hood, it can work with the existing setup without needing a brand-new trainer.Feedback on whether this approach makes sense would be appreciated, or let me know if you would prefer a more explicit integration — like introducing a dedicated trainer type for Unsloth even though it’s patching everything internally. There are also some dependency conflicts between Unsloth and Oumi at the moment.
