categorical encoder

[Scott]

Hi everyone,

I am working through a text book and I don't think my sklearn has the categorical encoder. I recently downloaded python 3 anaconda package so thought it would have everything.

Any ideas on how I can get the categorical encoder for my sklearn?

cat_pipeline = Pipeline([
        ('Selector', DataFrameSelector(cat_attribs)),
        ('Cat_encoder', CategoricalEncoder(encoding="onehot-dense")),
        ])

File "<ipython-input-21-92eef82c65d6>", line 3, in <module>
('Cat_encoder', CategoricalEncoder(encoding="onehot-dense")),

NameError: name 'CategoricalEncoder' is not defined
