There are some id form errors in the train_v2 dataset

Hi!

First of all, thanks for all your great work.

I find the ids in the train_v2 dataset form line 674 to line 893 are incorrect (220 lines in total). These ids are displayed using scientific notation, such as "1.33485426279969e+18". Could you have a look and hopefully update it please?

Thanks in advance!
