When I filled up every information I need to fill, and clicked at the submit button.
Then I double click the zip file, nothing happened. Is there someone know why?
Many thanks.
A few other participants encountered the same issue. However, for them it worked after a couple of trials.
I would suggest to push the submit button and have patience. Unfortunately Codalab does not show a progress bar during the uploading.
And try again if does not work a couple of hours later, eventually using another browser.
