## Usage

### Download and run inference

```bash
# Download checkpoint from HF Hub
huggingface-cli download ankile/openpi-pi05-real01c-insert-marker-d1-ours-sobol-r0base-ft-iris --local-dir <local_path>

# Run inference server
cd deps/openpi
uv run python scripts/serve_policy.py pi05_sir_droid_finetune \
  --checkpoint-dir <local_path>
```

### In-process inference (Python)

```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"]
```

## Checkpoint Format

[Orbax](https://github.com/google/orbax) format, all parameters in bfloat16.
