请问answer = NA是什么意思

[YirongWho]

我看到video_info_meta.jsonl中有些行的answer = NA是什么意思？

[YirongWho]

看起来是指数据集没有提供正确答案

Hi，N/A指的是测试集，如HF的readme所述：
Each entry in the video_info.meta.jsonl file contains a video sample. Some of the dataset has the ground truth answer (the DEV set) and some not (the TEST set). You could use the DEV set to optimize your dataset and upload the answer file to our leaderboard to see your model's performance.
