I used the start code to generate a 'submission.json', however, it failed to submit this file in the Codalab. And it said "Invalid file type (application/json)."Posted by: mlii0117 @ Aug. 21, 2020, 10:13 a.m.
You need to submit a zip version of your `submission.json, namely `submission.json.zip`. I hope this helps you.Posted by: tosho @ Sept. 28, 2020, 12:02 p.m.
