AttributeError:“系列"对象没有属性"searchsorted" pandas [英] AttributeError: 'Series' object has no attribute 'searchsorted' pandas

问题描述

我在第38页上重现了Python书籍的代码以进行数据分析

I reproduce the code of book python for data analysis in page 38

我写

prop_cumsum = df.sort_index(by='prop', ascending=False).prop.cumsum()

and prop_cumsum.searchsorted(0.5)

然后有一个错误说:

AttributeError                            Traceback (most recent call last)
<ipython-input-30-f2e2bb3f5ba0> in <module>()
----> 1 prop_cumsum.searchsorted(0.5)

C:\Users\xxx\AppData\Local\Enthought\Canopy32\User\lib\site-packages\pandas\core\generic.pyc in __getattr__(self, name)
   1813                 return self[name]
   1814             raise AttributeError("'%s' object has no attribute '%s'" %
-> 1815                                  (type(self).__name__, name))
   1816 
   1817     def __setattr__(self, name, value):

AttributeError: 'Series' object has no attribute 'searchsorted' 

我不明白为什么 我重新安装numpy和lib pandas 它仍然无法正常工作 熊猫文件中没有串联的搜索分类方法

I can't understand why i re-install numpy and lib pandas it still can't work It's no searchsorted methode in series in the document of pandas

推荐答案

您可能使用的是0.13.0或更高版本，其中Series现在是NDFrame的子类，您现在必须执行以下操作以返回一个numpy数组:

You are probably using a version that is 0.13.0 or later where Series now subclasses NDFrame, you have to now do this to return a numpy array:

prop_cumsum.values.searchsorted(0.5)

按搜索排序是一个numpy函数，而不是Pandas Series函数.

as searchsorted is a numpy function and not a Pandas Series function.
