Usage

Download and run inference

# Download checkpoint from HF Hub
huggingface-cli download ankile/openpi-pi05-franka-insert-marker-v2-dagger-r3-ft --local-dir <local_path>

# Run inference server
cd deps/openpi
uv run python scripts/serve_policy.py pi05_sir_droid_finetune \

In-process inference (Python)

from openpi.training import config as openpi_config
from openpi.policies import policy_config as openpi_policy_config

train_config = openpi_config.get_config("pi05_sir_droid_finetune")
policy = openpi_policy_config.create_trained_policy(
    train_config, "<local_path>"
)
result = policy.infer(obs_dict)
actions = result["actions"]
