input example set does not have a label attribute

Is there a way to get by without having label in test data?

Ah your process is not quite right. I would use the Cross Validation building block and encapusltate the Linear Regression/Apply Model/Perf measure in there. then pass the Test set. See this example:

This way you can an honest evaluation and performance measure of your model. 

 

Good luck on your Kaggle, let us know how well you place. We'll give you some swag.
