Error: _tkinter.TclError: no display name and no $DISPLAY environment variable

Hi,

First of all, thank you for your amazing work on this project! It has been incredibly helpful and well-structured.

I'm encountering an issue when trying to run runner/run_benchmark.py using the tkinter library. The error message I'm receiving is:

_tkinter.TclError: no display name and no $DISPLAY environment variable

A possible cause might be that the remote server I'm using doesn't have a graphical interface. This environment likely lacks a display server, which might be causing the issue.

Could you please advise on how to resolve this? Is there a way to run the script in a headless mode or another recommended approach to bypass this error?

Thank you once again for your hard work and dedication to this project!

Best regards, swzhangslg
