Run evaluation on custom dataset with arcface_torch

[Quanult]

I want to run evaluation on custom dataset with arcface_torch, but my dataset doesn't have the format like IJBC. I saw the eval/evalution.py but I dont know how to run it.
Is that eval/evalution.py the way to run evaluation on my dataset? Or is there someway else that I can do to run evaluation on my dataset. Please let me know.
Thank you!
