It seems unnecessary to have _format for both pred and target, could these be merged?

[okotaku]

@Ezra-Yu What do you think?

[Ezra-Yu]

Engineering-wise, it is indeed possible to use a function. but one of them has a topk argument and need raise different errors(pred, target). I've tried this, but it's almost like merging the two functions together directly (there are a lot of if/else statements), without reducing the amount of code. So I think it would be OK to keep them separate for the time being, as a private method, and have no qualms about rectifying them later.
