Error with training RL expert

Hi, I'm running run/train_rl.sh and keep receiving this error

I've browsed the issues page and found the same error from other person here, and the solution is delete the outputs/checkpoint.txt. But to me it was no help

@thoithoi58, after you delete outputs/checkpoint.txt, run train_rl.sh. Make sure you let enough training take place that something syncs with wandb. Copy the run_id from outputs/checkpoint.txt to rl_birdview_agent.py.

Here's my code: https://github.com/neilsambhu/carla-roach/blob/NeilBranch0/timeline/README3.md Go to timestamps (1) 6/19/2022 5:44 PM and (2) 6/20/2022 11:50 AM

Here is my rl_birdview_agent.py: https://github.com/neilsambhu/carla-roach/blob/NeilBranch0/agents/rl_birdview/rl_birdview_agent.py#L107 As of writing this message, I'm still waiting for my initial training to finish to see if my code to read in the run_id from the outputs/checkpoint.txt works.
