According to a survey by Forbes, data scientists and machine learning engineers spend around 60% of their time preparing data for analysis and machine learning. This module provides a bridge between Scikit-Learn 's machine learning methods and pandas -style Data Frames. In particular, it provides a way to map DataFrame columns to transformations, which are later recombined into features. You can install sklearn-pandas with pip: I had scikit-learn version 0.22.1 installed recently and had a similar problem.
