Error when running the play.py files in the tutorial.

[gadorneles]

Hello, I was able to train by following the README for the three different policies, especifically in the Isaac-Reach-OpenArm-Bi-v0 task. However, when I try to play, I get the following error in all three of them:

Traceback (most recent call last):
  File "/home/gdorneles/openrob_ws/src/openarm_isaac_lab/./scripts/reinforcement_learning/skrl/play.py", line 117, in <module>
    from isaaclab.utils.pretrained_checkpoint import get_published_pretrained_checkpoint
ModuleNotFoundError: No module named 'isaaclab.utils.pretrained_checkpoint'

I'm using:

Ubuntu 22.04
Isaac Sim 5.1.0
Python 3.11
