fit/transform API not working

[jonathanhexner]

Hi,

I'm getting the following error:
Python38\site-packages\featurewiz\featurewiz.py", line 3405, in transform
print('Returning dataframe with %d features ' %len(self.features))
TypeError: object of type 'NoneType' has no len()

It seems self.features gets used before being properly configured

Thanks. That indeed helped however something is still problematic, it's not going the feature engineering\selection:

feature_wiz = FeatureWiz(feature_engg=['groupby', 'target', 'interactions'], nrows=None,
transform_target=True, scalers="std",
category_encoders="auto", add_missing=False, verbose=0, imbalanced=False,
corr_limit=self.corr_limit,
ae_options={})
feature_wiz.fit(X, y)

when I do feature_wiz.transform(X), I get:

Starting featurewiz transform for test data

Loaded input data. Shape = (112560, 15)
Beware! feature_engg will add 100s, if not 1000s of additional features to your dataset!

Starting lazytransform for test data

LazyTransformer has not been fit yet. Fit it first and try again.
