AttributeError: 'PPO' object has no attribute 'actor_critic'

[JES0406]

After running:
./unitree_rl_lab.sh -p --task Unitree-G1-29dof-Velocity

I got the following error message:
Traceback (most recent call last): File "scripts/rsl_rl/play.py", line 137, in main policy_nn = runner.alg.policy ^^^^^^^^^^^^^^^^^ AttributeError: 'PPO' object has no attribute 'policy' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "scripts/rsl_rl/play.py", line 188, in <module> main() File "scripts/rsl_rl/play.py", line 140, in main policy_nn = runner.alg.actor_critic ^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'PPO' object has no attribute 'actor_critic'
