Hi, I am trying to make a classification using automl service , I've chosen KNN as model to train and for the primary metric i used accuracy . Based on the automl documentation the metric accuracy can be used with this type of classification task, but I get the error : AutoMLException: Message: Could not find a model with valid score for metric 'accuracy'. Please ensure that at least one run was successfully completed with a valid score for the given metric. when I checked azure ml studio I find this error of the run is that means that the dataset that i am using can be trained on KNN model ? ![197051-image.png][1] [1]: /answers/storage/attachments/197051-image.png
