Fitting and testing the model

In the previous exercise, you split the dataset into X_train, X_test, y_train, and y_test. These datasets have been pre-loaded for you. You'll now create a support vector machine classifier model (SVC()) and fit that to the training data. You'll then calculate the accuracy on both the test and training set to detect overfitting.
