@yaojm , Submission ID 9726515 generated a predictions file that was incorrectly formatted. This validation error should have been returned in the email - apologies if you did not receive it! (We recommend checking the spam folder, just in case.) In particular, the validation error is: ```python Invalid column names and/or types: Usecols do not match columns, columns expected but not found: ['was_early_preterm']. Expecting: {'participant': , 'was_early_preterm': , 'probability': }. ``` Because you are submitting to Task 2, the expected column should be named `was_early_preterm` rather than `was_preterm`. Hope this helps! EDIT: typo fix
@vchung Thank you! Could you also check on submission id:9726515? Many thanks! Jiaming Yao
