LGTM with a suggestion to also log the clip fraction of truncated completions
| self._metrics[mode]["max_completion_length"].append(max_completion_length) | ||
|
|
||
| # identify sequences that terminated with EOS and log their lengths | ||
| agg_terminated_with_eos = self.accelerator.gather_for_metrics(is_eos.any(dim=1)) |

Since we now have the sequences with / without EOS, WDYT about also logging clip_ratio_completion_length or truncated_completion_length_ratio as suggested in SimpleRL-Zero:

This is just num_terminated_completions / num_total_completions ?

No it's num_truncated_completions / num_total_completions (i.e. a high clip ratio means a lot of completions are too verbose)

Nice! Can you just add these new metrics to the doc (there is a section for this "logged metrics")
