tensorflow 0.9 skflow模型保存和恢复不起作用

Question

我已经在python3上将tensorflow从0.7更新到0.9，现在我不能使用skflow(tensorflow.contrib.learn)恢复以前保存的模型。.Here是在tensorflow 0.7上工作的示例代码示例。

import tensorflow.contrib.learn as skflow
from sklearn import datasets, metrics, preprocessing

boston = datasets.load_boston()
X = preprocessing.StandardScaler().fit_transform(boston.data)
regressor = skflow.TensorFlowLinearRegressor()
regressor.fit(X, boston.target)
score = metrics.mean_squared_error(regressor.predict(X), boston.target)
print ("MSE: %f" % score)

regressor.save('/home/model/')

classifier = skflow.TensorFlowEstimator.restore('/home/model/')

在tensorflow 0.9上，我收到了这个错误。

AttributeError: 'TensorFlowLinearRegressor' object has no attribute '_restore'
