  https://info.5y1.org/how-to-import-sklearn_1_003030.html

  This chapter introduces Hyperopt-Sklearn: a project that brings the bene-fits of automated algorithm configuration to users of Python and scikit-learn. Hyperopt-Sklearn uses Hyperopt [3] to describe a search space over possible configurations of scikit-learn components, including preprocessing, classification, and regression modules.

  Import some real data We will first import one of the datasets that is provided in sklearn. For a small example, we will. only take 20 datapoints. Additionally, we w ill only use one of the feature columns available in the feature matrix, i.e., to study linear regression with a single explanatory variable . We will also use
