Pandas: For loading the dataset into dataframe, Later the loaded dataframe passed an input parameter for modeling the classifier. A multi-output problem is a supervised learning problem with several outputs to predict, that is when Y is a 2d array of size [n_samples, n_outputs].. Multi-output problems¶. Sklearn: For training the decision tree classifier on the loaded … The required python machine learning packages for building the fruit classifier are Pandas, Numpy, and Scikit-learn. As of scikit-learn version 21.0 (roughly May 2019), Decision Trees can now be plotted with matplotlib using scikit-learn’s tree.plot_tree without relying on the dot library which is a hard-to-install dependency which we will cover later on in the blog post.
