unsloth单卡4090微调DeepSeek-R1-Distill-Qwen-14B医学领域后，跑通一下多卡微调。
1，准备2卡RTX 4090
2，准备数据集
医学领域
pip install -U huggingface_hub
export HF_ENDPOINT=https://hf-mirror.com
huggingface-cli download --resume-download --repo-type dataset FreedomIntelligence/medical-o1-reasoning-SFT --local-dir FreedomIntelligence/medical-o1-reasoning-SFT
3，安装LLaMA-Factory 和下载模型
需要提前搭建好docker微调环境
下载模型 ，需要是 safetensors 权重文件
git clone --depth 1 https://github.com/hiyouga/LLaMA-Factory.git
cd LLaMA-Factory
pip install -e ".[torch,metrics]"
llamafactory-cli webui
# llamafactory-cli version
INFO 04-12 04:48:24 __init__.py:190] Automatically detected platform cuda.

----------------------------------------------------------
/workspace# python toShareGPT.py 转换数据集
4，注册数据集
cp /datasets/medical_sharegpt_format.json ./LLaMA-Factory/data/
修改 `data/dataset_info.json`，添加自定义数据集：
"medical_sharegpt_format": {
"file_name": "medical_sharegpt_format.json",
"formatting": "sharegpt",
"columns": {
"messages": "conversations",
"system": "system"
}
}
5，llamafactory-cli webui训练
