How does NVFLARE save best_FL_global_model.pt?

Hi,

I’m using InTimeModelSelctionHandler in NVFLARE. If i have understood it correctly, to select the best fl global model, server will take the average of client’s validation metric in every round, the higher metric of round will be considered as the new best validation metric? But what model would be saved as the best_FL_global_model.pt? Is such round’s server model would be saved as best_FL_global_model.pt OR NVFLARE uses other way to save the best_FL_global_model.pt?

Thank you!
