🎓 兄弟们，想把开源大模型微调成自己想要的样子，Hugging Face 官方维护的 TRL 把整套后训练都备好了。 GitHub 上 1.9 万 star，DeepSeek R1 训练用的 GRPO 算法，在 TRL 里就是一个现成的训练器。今天刚发 1.13 版，上一版是 8 月 26 号。 以前想照着论文给模型做一遍偏好对齐或者强化学习，得自己写训练循环、算奖励、处理多卡，光把代码跑通就要耗掉不少时间。 在 TRL 里，从监督微调 SFT，到用偏好数据做 DPO，再到 GRPO 强化学习，每一步都有对应的 Trainer 直接调，不想写代码还能用命令行起训练。 显卡不够也有办法：接上 PEFT 用 LoRA、QLoRA…
