Hi, I believe this is because certain stats names have changed in recent times. Specifically, the error you sent shows that it is not able to get 'sim_seconds' from the stats file. Can you provide the stats file from your simulation?
It would be great if you can submit a change to gem5 dev doing these fixes.
