我发现了其他一些帖子,例如this one抱怨无法导入有关sklearn的一些信息,但是我尝试了所有建议的解决方案(归结为:pip3 install -U
和apt install
在每种情况下,甚至在帖子中询问preprocessor
以外的其他内容),但这仍然无济于事。
我遇到的问题是:
>>> import sklearn
>>> sklearn.__version__
'0.20.3'
>>> sklearn.preprocessor
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'sklearn' has no attribute 'preprocessor'
>>> from sklearn import preprocessor
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'preprocessor'
安装假定正确的软件包时的输出如下:
$ pip3 install -U scikit-learn

如您所见,该软件包应该以两种不同的方式正确安装,但是仍然无法正常工作。我还尝试卸载其中一个(以防它们相互干扰),但这也不能解决任何问题。
有人知道为什么这对我不起作用吗?如果我需要提供有关安装的任何其他信息,我很乐意提供。
答案 0 :(得分:1)
这在我之前也发生过,这是解决方法
import sklearn.preprocessing # or from sklearn import preprocessing
