无法从“ sklearn.preprocessing”导入名称“ StandardScalar”

Question

我正在尝试从Sklearn导入StandardScalar，但需要进行预处理，但这总是给我一个错误。

这是确切的错误：

ImportError                               Traceback (most recent call last)
<ipython-input-6-1f73df509116> in <module>
----> 1 from sklearn.preprocessing import StandardScalar

ImportError: cannot import name 'StandardScalar' from 'sklearn.preprocessing' (c:\users\abhijith rao\appdata\local\programs\python\python37-32\lib\site-packages\sklearn\preprocessing\__init__.py)

from sklearn.preprocessing import StandardScalar

Answer 1

造型错误

StandardScalar-> StandardScaler

https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.StandardScaler.html

Answer 2

是StandardScaler而不是StandardScalar 所以， 将行“ from sklearn.preprocessing import StandardScalar”替换为 “从sklearn.preprocessing导入StandardScaler”
