Description

Describe the question

Hi team,

I am encountering a significant inconsistency when evaluating my model. I ran the exact same model twice on the same case, but the results are completely different.

Test Case Details:

  • Route ID: 2091
  • Town: Town12

Evaluation Results:

  • Run 1: score_composed = 21.14 (Failed)
  • Run 2: score_composed = 100.0 (Completed)
Questions
  1. Is this level of variance normal for this evaluation framework?
  2. Is the randomness in the environment (e.g., NPC behaviors, traffic manager, spawning) expected to cause such a huge gap between two runs?
  3. Are there any specific configurations or random seeds I should fix to ensure reproducible evaluation results?

Thanks in advance for your help!

Research direction

Start by reproducing route 2091 in Town12 twice with the same model and evaluation configuration. Check whether NPC behavior, traffic-manager behavior, spawning, or random seeds differ between runs; done means identifying whether the variance is expected and documenting the configuration needed for reproducible results.
