training script question

[ruida]

Hi,

coco_fine.sh:
data=${data_dir}/fineseg_refined_val2017.tsv,${data_dir}/fineseg_refined_val2017.tsv
coco_unseen.sh:
data=${data_dir}/unseen_val2017.tsv,${data_dir}/unseen_val2017.tsv

Could you leave me input on why the two valid dataset TSV files were specified in the data variable?

Thanks,
