sf export

Convert a checkpoint to HuggingFace format

sf export my-grpo \
  --checkpoint checkpoints/step_500 \
  --checkpoint-format nemo-dcp

把训练 checkpoint 转成 HuggingFace 格式——Playground、模型部署，以及这个平台之外的一切， 能加载的都是这个格式。

--checkpoint 填产物登记表里记录的那个路径，从作业的 Artifacts 页或 sf job status 读。--checkpoint-format 必须和框架实际写出的格式一致； 填错会尽早失败，并列出它接受哪些格式。

​

推到 Hub

sf export my-grpo \
  --checkpoint checkpoints/step_500 --checkpoint-format nemo-dcp \
  --push-repo alice/qwen-support-v3

需要先关联 Hugging Face 账号，见 Hugging Face。

​

训练后自动导出

sf submit my-grpo --profile h200:8 --then export

run 一成功就导出最后一个 checkpoint，不用谁去记着这件事。
