Where can I find the ROUGE-L metric mentioned in the paper?

Sorry, I may not look into your codes carefully, but could you please show me where you put the ROUGE-L implementation? Thanks.

I think you've found where it is, but let me leave a comment just in case.

The authors declared rouge scorer object here,
and filtered out instructions that have higher score than the threshold here.
