Answer 1

pip install --upgrade category_encoders

现在，重启你的内核

import category_encoders as... 等等等等

此外，您可以查看 sk-learn 的预处理类 CategoricalEncoder ...

from sklearn.preprocessing import CategoricalEncoder

从这里获得 sk-learn，

pip install git+git://github.com/scikit-learn/scikit-learn.git

或者干脆

pip install sklearn
