- 发生了什么
- TRL v1.14 now supports LoRA-only training with AsyncGRPOTrainer, syncing only adapter weights instead of full models across distributed jobs.
- 为何重要
- Engineers scaling reinforcement learning training across separate machines without shared filesystems or NCCL, using Hugging Face Jobs infrastructure.
- 注意
- Requires careful adapter slot management based on max_staleness to prevent silent policy mismatches; vLLM version pinning and specific runtime flags are essential for correctness.
