I guess, this could overcomplicate ui, I don't see a good solution yet.

as a quick hack, we can just use separate name (eg "best_val_roc_auc") for all metric values for the current best checkpoint. then we can just add columns with the last value of this metric

exactly

DilapidatedDucks58 I see ...
This might be more complicated that one would imagine, a simple solution might be to store a snapshot of the values every-time we reach a new maximum, a quick hack might be to add it as text on one of the task's parameters or properties (that we can later add to the table as custom column).
wdyt?

Hi DilapidatedDucks58

eg, we want max validation accuracy and all other metric values for the corresponding epoch

Is this the equivalent of nested sort ?
Wouldn't you get the requested behavior if you add all metric columns but sort based on the "accuracy" column ?

Okay, I think I lost you...
DilapidatedDucks58 you mean detect at which "iteration" the max value was reported, and then extract all the other metrics for that iteration ?

I don't think so because max value of each metric is calculated independently of other metrics

so max values that I get can be reached at the different epochs
