Caption for training dataset

[ug-kim]

Thank you for sharing your awesome work.

I want to train your model, but I have one question.

How did you get "caption" for the training dataset?
There is no configuration or explanation about captions on GitHub or in the paper.
And are the captions essential for the training?

Thanks!

Caption is not used in our training. It is just a file storing ids of the training samples.
