ValueError: invalid literal for int() with base 10

Dear Prodigy support,

during my labeling session, I suddenly got the ValueError message indicated in the subject of this ticket. It is linked on a particular n-grams I have tagged. I have saved the labelled session, apparently without any problem. But when I try to restart the server to continue labelling, I cannot.

Thanks for your help.
Best regards
Jerome

Hi! Could you share some more details on the error and include the full traceback so we can see where it happened and what may have caused it?
