錯誤從sklearn

Question

進口CountVectorizer當我嘗試以下import語句

from sklearn.feature_extraction.text import CountVectorizer 

我得到以下錯誤：

我目前使用的是Windows 8 64位，PyCharm 4.5.1與Python 2.7.1（64位），並已安裝scikit學習0.16.1和它的依賴關係（Numpy 1.9.2和0.15.1列在Scikit Installation guide）：

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

也許嘗試使用anaconda？我認爲這是更受歡迎的scipy發行版之一，並且非常穩定。另外請確保您使用pip或其他軟件包管理器來安裝軟件包。
