We can get rid of these checks. Empty callback tuple should be allowed and return None, None which it does in the code below already. And if callbacks has more than two values then it will be detected by the duplicate checks below.

This one can be removed since we're checking before both callbacks

The float type hint includes int, so remove int and the noqa

remove int since float includes the int type hint, and also remove noqa

Fixes #635 Callback tuple support and exam callback
Description
This PR implements Phase 2 of the callback redesign for EBM training.
Phase 1 changed the callback API to keyword-only arguments and ensured the
progress callback only fires on progressing boosting steps. That work was
merged in #662.
This PR builds on top of that by allowing
callbackto accept either:The supported callback signatures are:
Why
The original callback parameter was carrying more than one kind of signal.
As discussed in the review for #662, there are really two different callback
use cases:
gain was computed for it
Splitting those concepts makes the API clearer while still keeping a single
