当我尝试以下导入语句时

from sklearn.feature_extraction.text import CountVectorizer

我收到以下错误：

我目前正在使用 Windows 8 64 位、PyCharm 4.5.1 和 Python 2.7.1（64 位）并且已经安装了 scikit-learn 0.16.1 及其依赖项（Numpy 1.9.2 和 0.15.1如Scikit Installation guide中所列）：

Python（>= 2.6 或 >= 3.3）
NumPy (>= 1.6.1)
SciPy (>= 0.9)

也许尝试使用 Anaconda？我认为这是更流行的 scipy 发行版之一，而且非常稳定。还要确保您使用pip 或其他包管理器来安装您的包。
