I know, i haven't made any changes to BaseCheckpointCallback here. But i wonder why do we have to do it this way, changing base class, if such logic is complex enough?

@TezRomacH What do you think about this solution?

I'm gonna check it tonight, thanks a lot for participating ❤️

@Arquestro could you add the same logic to IterationCheckpointCallback?

@Arquestro could you add the same logic to IterationCheckpointCallback?

No problem for me, but are you sure that's okay to duplicate such logic? I mean, that it maybe doesn't fit the base class but double the code.

@Arquestro For now we can try the proposal with "double code" and then check out how we can improve it. Before that – it can be overoptimization.
Maybe, we will see the general part between them and implement good solution.

Done
