FAQPage Schema

How do I set up the Cosmos3 framework for physical-AI inference?▼

To set up the Cosmos3 framework, you must validate source repositories, stage model checkpoints, and configure environment variables for GitHub, Hugging Face, and NGC to ensure secure deployment.

Do I need Hugging Face and NGC credentials to stage Cosmos3 model checkpoints?▼

Yes, you need verified environment variables for both Hugging Face and NGC. These credentials are required to securely download and cache model checkpoints to ephemeral storage.

Can I use SkyPilot for GPU-accelerated tasks with the Cosmos3 environment?▼

Yes, Cosmos3 environment setup supports workflows involving SkyPilot integration for GPU-accelerated tasks. It guides you to the appropriate NPA workflow based on your infrastructure needs.

What does Cosmos3 environment validation check for during setup?▼

Environment validation automatically checks for source repository reachability, Hugging Face access, and the presence of necessary environment variables to ensure compliant model deployment.

Why does my Cosmos3 checkpoint staging fail before inference?▼

Checkpoint staging fails when environment variables for GitHub, Hugging Face, or NGC are missing or unverified. The setup requires validated credentials to ensure secure and compliant downloads.
