Question

最近我更新了anaconda的软件包，以便安装keras和tensorflow。现在我的程序在下一行失败了：

from sklearn.preprocessing import LabelEncoder, OneHotEncoder.

Traceback (most recent call last):

  File "<ipython-input-1-83540d56f55d>", line 1, in <module>

你可以帮我解决一下。

Answer 1

从头开始重新安装解决了这个问题，已安装的软件包中存在一些版本冲突。

Answer 2

在我的情况下，我升级scikit学习包。然后转到anaconda navigator环境，然后搜索scikit learn

然后升级它并同时升级scipy（相同的过程）

＆＃34;来自sklearn.preprocessing导入LabelEncoder，OneHotEncoder＆＃34;更新Anaconda中的软件包后失败
