I have been submitting a file with all zeros just to make sure that I have got the submission format correctly. I put only the result column in the submission file, so that each row has only one number as shown below.
| 0 |
| 0 |
But evaluation status always results in 'test cases with no predictions' and the score is 'NA'.
Could you clarify if I should include the reference id as well in the submission file, or if my data format is incorrect?
Your data format looks correct, you shouldn't upload the reference id in the file. It should only contain single number as an answer for each test case, ordered as in test cases datafile.
Please chcek that you have exactly one number for every test case, these should be exactly 12724 rows.
I have just created the file with all 0 answers and evaluation worked fine(you can find my score at the end of the leaderboard).
Also make sure that you are submiting a file in csv format.
If you have any questions I will be glad to answer.
