用NVIDIA NeMo AutoModel在Colab单GPU微调Qwen3的LoRA教程
Fine-Tuning Qwen3 with LoRA Using NVIDIA NeMo AutoModel: A Complete Single-GPU Google Colab Workflow Tutorial
教你用Colab单GPU跑Qwen3-0.6B的LoRA微调，全程实操，从环境配置到API调用都有，适合想上手NeMo的低资源玩家。
该教程展示了如何在Google Colab单GPU上使用NVIDIA NeMo AutoModel微调Qwen3-0.
6B模型。从验证CUDA硬件开始，安装NeMo AutoModel源码，加载官方LoRA配置。
在受限运行时调整精度、批次大小、检查点和调度器设置。通过automodel CLI启动微调，加载LoRA检查点后比较基础模型与微调输出的差异。
最后演示NeMoAutoModelForCausalLM Python API的使用。
Fine-Tuning Qwen3 with LoRA Using NVIDIA NeMo AutoModel: A Complete Single-GPU Google Colab Workflow Tutorial
We build an end-to-end NVIDIA NeMo AutoModel workflow in Google Colab using a single GPU. We verify CUDA hardware and precision support, install NeMo AutoModel from source, and load an official Qwen3-0.6B LoRA recipe. We then adapt its precision, batch size, checkpointing, and scheduler settings for a constrained runtime. We launch fine-tuning through the automodel CLI, reload the LoRA checkpoint, and compare base versus fine-tuned outputs. We finish with the NeMoAutoModelForCausalLM Python API.
