From the Hugging Face model README
polaris_pi05_sft
Fine-tuned π0.5 (pi05) DROID policy for the Polaris real2sim stack.
- Base config:
pi05_droid(openpi) - Recipe:
pi05_droid_jointpos_lerobot_finetune_polaris(joint-position SFT on the Polaris LeRobot dataset) - Checkpoint step: 19999 (final)
- Contents: inference-ready only —
params/+assets/droid/norm_stats.json. The optimizertrain_state/is not included, so this checkpoint serves but cannot resume training.
Usage
Download the repo and point the Polaris openpi client at it:
huggingface-cli download Makolon0321/polaris_pi05_sft --local-dir /path/to/ckpt
export POLARIS_PI05_CKPT=/path/to/ckpt
The repo root acts as the openpi checkpoint dir; create_trained_policy reads
params/ and assets/ from it:
from openpi.policies import policy_config
from openpi.training import config as _config
train_cfg = _config.get_config("pi05_droid")
policy = policy_config.create_trained_policy(train_cfg, "/path/to/ckpt")
