Unable to find the file: last_ant_ep_500_rew_73.78369.pth

When I tried the tutorial in the official documentation of IsaacLab, this error occurred after running it. Isaacsim opened and quickly closed, unable to display the training results.

Creating window for environment.

my command is
./isaaclab.sh -p source/standalone/workflows/rl_games/play.py --task Isaac-Ant-v0 --num_envs 32 --checkpoint last_ant_ep_500_rew_73.78369.pth

Hi @2832536846,
With rl_games, checkpoint has to be the path to the pth file and not just its name.
