运行时出现NLTK Python错误

Question

我已经在nltk中安装了anaconda并在本教程中尝试了一些示例pythonprogramming.net

在运行Classifier saving example 之后，它在anaconda控制台上显示了一些错误，如下所示：

当我尝试再次安装时，它显示如下：

C:\Users\Kalanka PC>pip install nltk

Answer 1

这里python文件的命名与pickle相同。因此在加载相关文件时会混淆。例如：文件名是pickle.py，代码如下：

`import nltk` 
`import random`
`import pickle`

Answer 2

您可能已经保存了名为pickle.py的文件，因为它尝试导入pickle文件而不是模块中的标准pickle。

我在使用泡菜时遇到了类似的问题，我用名称pickle保存了代码文件。然后当我执行它时，查找你创建的文件而不是标准模块pickle
