The authors present Retro-BLEU which is a statistical metric to evaluate the plausibility of retrosynthesis routes. I was asked to perform a data and code review. While the code satisfies most of the criteria within the data review checklist (attached). My only minor comment is that the authors need to clarify which versions of the datasets and the code dependencies did they use for the study.

The authors have successfully answered all my queries as part of the data and code review.
