Ch.2 Error using corr()

[rejgrant]

I am getting the following error while using corr_matrix = housing.corr(), I know the method should exclude non-numerical columns, can't understand this error.
" ValueError: could not convert string to float: 'INLAND' "

Try this:-
housing_encoded = pd.get_dummies(housing, columns=['INLAND'], drop_first=True)
corr_matrix = housing_encoded.corr()
