tensorflow

I am building a model with 3 classes: [0,1,2]
After training, the .predict function returns a list of percentages instead.
I was checking the keras documentation but could not figure out, what I did wrong.
.predict_classes is not working anymore, and I did not have this problem with previous classifiers. I already tried different activation functions (relu, sigmoid etc.)
If I understand correctly, the number inDense(3...) defines the amount of classes.
