The GridSearchCV process will then construct and evaluate one model for each combination of parameters. Cross validation is used to evaluate each individual model, and the default of 3-fold cross validation is used, although you can override this by specifying the cv argument to the GridSearchCV constructor. http://www.duoduokou.com/python/17252403328985040838.html
