Question

I write the following code, Here I attached the code image from sklearn.preprocessing import OneHotEncoder ohe = OneHotEncoder(categorical_features=[0])

and it gives me, TypeError: OneHotEncoder.init() got an unexpected keyword argument 'categorical_features'

I tried to creating, OneHotEncoder object with keyword argument. But it gives me TypeError

Answer 1

The error is telling you that the init function for the class does not take a keyword argument with that name. The documentation says this:

class sklearn.preprocessing.OneHotEncoder(*, categories='auto', drop=None, sparse='deprecated', sparse_output=True, dtype=<class 'numpy.float64'>, handle_unknown='error', min_frequency=None, max_categories=None, feature_name_combiner='concat')
