tf.estimator.LinearRegressor报错'tensorflow.python.estimator.estimator' has no attribute 'LinearRegre

tf.estimator.LinearRegressor报错AttributeError: module 'tensorflow.python.estimator.estimator_lib' has no attribute 'LinearRegressor'

在使用TensorFlow中的模块tf.estimator.LinearRegressor时，报错如下所示：

Traceback (most recent call last):
  File "D:/Python27/Lib/site-packages/django/bin/pylearn/deeplearning/tensorflow/tf9.py", line 8, in <module>
    estimator = tf.estimator.LinearRegressor(feature_columns=feature_columns)
AttributeError: module 'tensorflow.python.estimator.estimator_lib' has no attribute 'LinearRegressor'

解决方案：

（1）将

estimator = tf.estimator.LinearRegressor(feature_columns=feature_columns)

替换为

estimator = tf.contrib.learn.LinearRegressor(feature_columns=feature_columns)

（2）如果用到 estimator.train( ），则替换为  estimator.fit()
