load_from_csv is never called

[gathierry]

Hi, the wan example suggests using csv data format. However, I find the function load_from_csv is never called in the code. Did I miss anything?

And as estimate_data_tokens_per_row needs key ["messages"] to estimate token length, the format video,prompt in readme might not work.

I remember we clean and updated the config after the release for wan. Maybe current example config is not correct? @BIGKnight . Thanks!
