WebJun 13, 2024 · GridSearchCV is a function that comes in Scikit-learn’s (or SK-learn) model_selection package.So an important point here to note is that we need to have the Scikit learn library installed on the computer. This function helps to loop through predefined hyperparameters and fit your estimator (model) on your training set.
