unable to pass the test

[wittycheng]

hi,this is really great work. I want to use MEP and PECAN in this repo but when I was installing and run run_test.py as mentioned in readme I shows this error

and my overcooked_ai version is this

. I think there might be something wrong with overcooked_ai

[wittycheng]

In a word I don't know whether to use overcoooked_ai in this repo or some branch of https://github.com/HumanCompatibleAI/overcooked_ai

[wittycheng]

I know that the main branch don't have this error. But from the folder names I don't think the code used here is the same as main

[wittycheng]

I see that some file is ignored in this folder?
