Questions About Using InteractionSimulator

[ShenZC25]

It's my pleasure to read your paper, and I'm sorry to disturb you. I have some questions about "InteractionSimulator". Question I: downloaded and installed the related components as required, but failed when running "test_collision_stop.py".It shows "Type Error: close() got an unexpected keyword argument 'filestr'". Question 2: I see that there are a lot of defined functions in this environment, so do I need to define a file myself to call it? If you have time, could you please help me solve my problem? Thanks.
