解决问题
sklearn.exceptions.NotFittedError: This StandardScaler instance is not fitted yet. Call 'fit' with appropriate arguments before using this estimator.
解决思路
sklearn异常未装配错误:此StandardScaler实例尚未装配。在使用这个估计器之前，使用适当的参数调用“fit”。
解决方法
ss_X = StandardScaler()
ss_y = StandardScaler()
X_train = ss_X.fit_transform(X_train)
X_test = ss_X.transform(X_test)
