无法导入nltk

Question

我想在程序中导入nltk以下载语料库。但是我得到了一个错误：

Traceback (most recent call last):

    from nltk.classify.scikitlearn import SklearnClassifier
ImportError: No module named scikitlearn

任何帮助都将不胜感激。我使用anaconda下载了nltk，我使用的是windows机器。

Answer 1

我相信这个模块叫做sklearn，或者叫做scikit-learn。请参阅https://docs.continuum.io/anaconda/

Answer 2

我觉得你在用

import scikit-learn

没有名为scikit-learn的模块。你应该使用

import sklearn

如果上面的方法不起作用，

尝试使用anaconda python您应该尝试以下操作

conda install scikit-learn

并添加此代码以提高性能-如果未安装

conda install numpy
