I wonder is there any attribute like "get_normalized_score" in D4RL? or where can i find the reference reward for each task?
Thank you!

Hi @Jiang-524,
You can find the reference rewards in the metadata:

import minari

dataset = minari.load_dataset("D4RL/antmaze/medium-play-v1", download=True)
print(dataset.storage.metadata["ref_max_score"])
print(dataset.storage.metadata["ref_min_score"])
