Fit the model(s)

You're finally ready to fit the models and select the best one!

Unfortunately, cross validation is a very computationally intensive procedure. Fitting all the models would take too long on DataCamp.

To do this locally you would use the code:

# Fit cross validation models
models = cv.fit(training)

# Extract the best model
best_lr = models.bestModel

Remember, the training data is called training and you're using lr to fit a logistic regression model. Cross validation selected the parameter values regParam=0 and elasticNetParam=0 as being the best. These are the default values, so you don't need to do anything else with lr before fitting the model.
