SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

End-to-end capability to fine-tune and serve robot policy models built on OpenPI, enabling seamless adaptation of pi0/pi0-fast/pi0.5 to robot tasks.

Core Features & Use Cases

  • Fine-tune pi0/pi0-fast/pi0.5 models on custom datasets and convert to serving-friendly checkpoints.
  • Serve policies for ALOHA, DROID, and LIBERO environments with WebSocket or CLI interfaces.
  • Support both JAX and PyTorch training paths and checkpoint conversion.

Quick Start

Clone the OpenPI repository, install dependencies, and start the policy server to begin fine-tuning and serving OpenPI models.

FAQPage Schema
How do I fine-tune OpenPI robot policy models like pi0 on custom datasets?▼

Serving OpenPI policies for real-time robot control involves deploying converted checkpoints via WebSocket or CLI interfaces. This allows the adapted pi0, pi0-fast, or pi0.5 models to execute actions across ALOHA, DROID, and LIBERO environments during live operation.

What Python and framework versions do I need to set up OpenPI policy training?▼

OpenPI supports both JAX and PyTorch training paths for fine-tuning robot policies. After training your pi0, pi0-fast, or pi0.5 model in either framework, you convert the resulting checkpoint to a serving-friendly format, ensuring flexibility across different machine learning workflows.

Can I deploy fine-tuned pi0 models for ALOHA and DROID environments?▼

Yes, you can deploy fine-tuned pi0, pi0-fast, and pi0.5 models for ALOHA, DROID, and LIBERO environments. The OpenPI workflow enables serving these policies via WebSocket or CLI interfaces for real-time robotic control across these specific simulation and physical setups.

What is the process for converting OpenPI checkpoints for policy serving?▼

Checkpoint conversion for OpenPI policy serving takes your fine-tuned JAX or PyTorch model and transforms it into a serving-friendly format. This step is necessary before starting the policy server to enable real-time robot control via WebSocket or CLI interfaces.
