Train a simple model
As you determined, you are dealing with a regression problem. So, now you're ready to build a model for a subsequent submission. But now, instead of building the simplest Linear Regression model as in the slides, let's build an out-of-box Random Forest model.
You will use the RandomForestRegressor class from the scikit-learn library.
Your objective is to train a Random Forest model with default parameters on the "store" and "item" features.
