StandardScaler`. ndarray' object has no attribute 'fit' when calling fit_transform on a pipeline 5 RandomUnderSampler' object has no attribute 'fit_resample' So to call this method and then (since it returns the instance) to call the transform method (don't forget the parentheses, and the fit function has a non optional unused argument, not sure why you did that), you should do: If you're using a relatively recent version of sklearn, then CountVectorizer has renamed the function you're trying to use as get_feature_names_out. This parameter exists only for compatibility with Pipeline. Anyone with more experience know what to 我使用的是Spark v3. Returns: self. Expected Behavior: You signed in with another tab or window. However, when I decide to apply the same pipeline to the test data in order to transform it so I can generate predictions with the various classifiers, things go wrong. I would recommend pandas.

I am doing churn prediction using keras. ‘ignore’ : When an unknown category is encountered during transform, the resulting one-hot encoded columns for For classification, I was trying to convert categorical data into numeric by applying OneHotEncoder. Provide details and share your research! But avoid . Labels. You need to fit it first - before fitting, the attribute does not exist indeed: encoder = OneHotEncoder(inputCol="index", outputCol="encoding") encoder. compose import ColumnTransformer, make_column_transformer from sklearn.

You switched accounts on another tab or window. Imo, the first consideration to be done is that CountVectorizer() requires 1D input; your example is not working because the imputation is returning a 2D numpy array which means that you'll need to add a customized treatment to make it work. Its Transform method returns a sparse matrix if sparse=True, otherwise it returns a 2-d array. setDropLast(False) ohe = Call the transform method on the OneHotEncoder object with the input data.
