python - How can I fix this error with sklearn.preprocessing?

Question

Code:

onehotencoder = OneHotEncoder(categorical_features = [3])

resulting in the error:

TypeError: __init__() got an unexpected keyword argument 'categorical_features'

Answer 1

正如 Chris 所说，scikit-learn 的 0.20 版已弃用categorical_features参数 for 。preprocessing.OneHotEncoder请参阅相关的发行说明、提交、拉取请求和问题以了解弃用。然后在 0.22 版中将其删除。请参阅PR并提交以进行删除。
