FAQPage Schema
How do I fine-tune a VLM action model for autonomous vehicle navigation?

Fine-tune a VLM action model for autonomous vehicle navigation by running the Alpamayo-1.5 pipeline on the PAI dataset with navigation conditioning to predict trajectories guided by route instructions. The process automates training and evaluation end-to-end.

Can I train a visual question answering model for driving scenes using LingoQA?

Yes, you can train a visual question answering model for driving scenes using the LingoQA dataset. The Alpamayo-1.5 fine-tuning pipeline automates the training process specifically for driving scene question answering.

What datasets are supported for Alpamayo-1.5 supervised fine-tuning?

The datasets supported for Alpamayo-1.5 supervised fine-tuning are PAI and LingoQA. PAI is used for navigation conditioning and trajectory prediction, while LingoQA is used for visual question answering in driving scenes.

Do I need DeepSpeed to run the two-stage training pipeline for trajectory diffusion?

DeepSpeed is supported to ensure efficient training during the two-stage pipeline, though the optional Stage 2 specifically handles trajectory diffusion expert training. The pipeline also leverages gradient checkpointing to optimize resources.

How does the Alpamayo-1.5 model handle checkpoint conversion before training?

The Alpamayo-1.5 model requires converting the release checkpoint to A1 format before training begins. This conversion is a necessary preparatory step before executing the two-stage training pipeline on your prepared datasets.
