Restrictions on the Prediction

[ramber1836]

Dear all,

The prediction yielded by your submitted model should not have abnormal values, which means empty prediction, NaN prediction, or the prediction with identical values will be punished w.r.t. the final score your model can obtain.
Please refer to the newly updated evaluation script.
