`from sklearn.model_selection import GridSearchCV param_grid = {'polynomialfeatures__degree': np.arange(21), 'linearregression__fit_intercept': [True, False], 'linearregression__normalize': [True, False]} grid = GridSearchCV(PolynomialRegression(), param_grid, cv=7) **grid.fit(X,y)**` ------------------------------------------------- Sorry to bother you. I had a small issue...
