WebApr 1, 2024 · If it is categorical you need to use DecisionTreeClassifier instead of DecisionTreeRegressor. If it is continuous, you need to change the metric accuracy_score for example for r2_score. I also noticed you named your model df.model but when predicting this is named df_model. So I recommend to change both to df_model. Hope it helps!
