title: How to scale the input data for trained model?
body: <p>I have a trained model that uses regression to predict house prices. It was trained on a standardized dataset (StandatdScaler from sklearn). How do I scale my models input (a single example) now in a different python program? I can't use StandardScaler on the input, because all features would be reduced to 0 (MinMaxScaler doesn't work either, also tried saving and loading scaler from the training script - didn't work). So, how can I scale my input so that features won't be 0 allowing the model to predict the price correctly?</p>
