You use the designer to create a training pipeline for a classification model. The pipeline uses a dataset that includes the features and labels required for model training.
You create a real-time inference pipeline from the training pipeline. You observe that the schema for the generated web service input is based on the dataset and includes the label column that the model predicts.
Client applications that use the service must not be required to submit this value.
You need to modify the inference pipeline to meet the requirement.
