我如何解决sklearn.preprocessing的错误？

Question

代码：

onehotencoder = OneHotEncoder(categorical_features = [3])

得到以下错误：

TypeError：init（）获得了意外的关键字参数'categorical_features'

Answer 1

As Chris said，[c0]的categorical_features参数在scikit-learn的0.20版本中已弃用。弃用请参见preprocessing.OneHotEncoder，preprocessing.OneHotEncoder，the relevant release notes和commit。然后在版本0.22中将其删除。请参阅pull request和issue进行删除。
