Out of it, the data has dimensions of (1, n_samples) instead of (n_samples, 1). The new CategoricalImputer from the sklearn-pandas works but it can't be exported to PMML. Any help to fix this? Many thanks!!

1.12. Multiclass and multioutput algorithms - scikit-learn Multiclass-multioutput classification (also known as multitask classification) is a classification task which labels each sample with a set of non-binary properties. Both the number of properties and the number of classes per property is greater than 2. A single estimator thus handles several joint classification tasks.
