Hi @zhizhuo0928

This is a hydra/omegaconf (argument) limitation described in [Question How to set bounds to my action and observation spaces and also change its type? · isaac-sim/IsaacLab · Discussion #1264 · GitHub.

However, that isssue was resolved a month ago.
Are you using latest Isaac Lab version?
