Often times you may find yourself going back to a previous model to see what assumptions or settings were used when diagnosing where your prediction errors were coming from. Perhaps there was something wrong with the data? Maybe you need to incorporate a new feature to capture an unusual event that occurred?

In this example, you will practice saving and loading a model.
