About data split

[Wickked-swag]

Hello authors,I download SSV2 from the official website，but the split of the data set looks different than yours.
For example, the official data look like :"78687 54 19" ,that is the video id,frame number of video and the categories of video .
but yours look like:"train8/78687",What does that mean? Why do two videos with the same id correspond to different categories?
Is there something wrong with my understanding? Please help me. Thank you very much.

Hi, do you understand what does the train/8 mean? I am also confused about this.
