Use the trained k-NN classifier model to classify new, previously unseen objects

Question

fruit_prediction = knn.predict([[20, 4.3, 5.5]])

lookup_fruit_name[fruit_prediction[0]]

I am not able to run above two lines. I am getting this kind of error

ValueError: query data dimension must match training data dimension

Answer 1

Checking the inputs of knn classifier would be good option to analysed what is wrong in the dimensions of knn.predict. As you have nested list in your predict as inputs that can be just a list.
