AttributeError: 模块“tensorflow_estimator.python.estimator.api._v1.estimator”没有属性“inpus”

问题描述

我正在尝试使用线性分类器进行预测，这里列出了估计器的构建和训练：

model = tf.estimator.LinearClassifier(
  n_classes = 2,model_dir = "ongoing",feature_columns = categorical_features + continuous_features
(
FEATURES = ['Age','Gender','ICD9Code']
LABEL = 'Condition'

def get_input_fn(data_set,num_epochs,n_batch,shuffle):
    input = tf.compat.v1.estimator.inputs.pandas_input_fn(
       x = pd.DataFrame({k: data_set[k].values for k in FEATURES}),y = pd.Series(data_set[LABEL].values),batch_size = n_batch,num_epochs = num_epochs,shuffle = shuffle
     )
     return input
model.train(
  input_fn = get_input_fn(csv_data,num_epochs = None,n_batch = 10461,shuffle = False
  ),steps = 1000
)
predict_data = pd.read_csv('feature_condition.csv',usecols = ['PatientGuid','Age','ICD9Code'],nrows = 5)
predict_input_fn = tf.estimator.inpus.numpy_input_fn(
                      x = {"x": predict_data},y = None,batch_size = 5,shuffle = False,num_threads = 5
                   )
predict_results = model.predict(predict_input_fn)
print(predict_results)

出现错误：

AttributeError: module 'tensorflow_estimator.python.estimator.api._v1.estimator' has no attribute 'inpus'

我的 tensorflow 版本是 2.4.1

你能帮我解决这个问题吗？谢谢！

更新：我已经更正了拼写错误，错误也已修复，但我在此处列出了一个警告：

The name tf.estimator.inputs.numpy_input_fn is deprecated. Please use tf.compat.v1.estimator.inputs.numpy_input_fn instead.

在我使用建议的函数后，我在这里列出了相同的警告：

The name tf.estimator.inputs.numpy_input_fn is deprecated. Please use tf.compat.v1.estimator.inputs.numpy_input_fn instead

这真的让我很困惑，你能帮忙解决吗？谢谢！

我在谷歌驱动器中上传了我的完整代码，这是这里的链接： https://drive.google.com/file/d/1R6bRcv8Afjx4cPLBZaBpuCcDg71fNN3Y/view?usp=sharing

解决方法

如果您可以将 tf.estimator.inpus.numpy_input_fn 更改为 tf.estimator.inputs.numpy_input_fn，您的问题可以得到解决。这是打字错误。
