Sorry for the problem!
This is somthing new for us. We will investigate this error in the next 2-3 days.
From our end, it looks as you tried to submit a solution file with the same content as an already succesfully submited one. The name is not taken into this check - just the actual content.
On a side note, you already had some succesfuly submitted solutions and the best among them is displayed on the leaderboard (currently it is top2).
Yes, but those previous solutions are from the past. I will check but specially being a regression problem, is very hard to have the actual exact output.
I will modify the first value and try again. But so far the new submissions all they failed.
Found it, it indeed was the same content, typo in the code.
Probably a good idea to change the error message, it would have been trivial to solve if it provides a bit more detail.
Also, for some applications, the same output can be valid, e.g. maybe the models are similar, specially those where you need to post-process the output to fit a set.
