Stuck on an issue?

Hi, I tried to get the Scikit-learn example from the documentation to work

# Initialize a FeatureExtractor, which subselects only the features we want
# to run the Standard Scaler against
input_features = ['a', 'c', 'd']
output_vector_name = 'unscaled_continuous_features' # Used only for serialization purposes
output_features = ["{}_scaled".format(x) for x in input_features]

feature_extractor_tf = FeatureExtractor(input_scalars=input_features,
                                        output_vector=output_vector_name,
                                        output_vector_items=output_features)


# Define the Standard Scaler as we normally would
standard_scaler_tf = StandardScaler(with_mean=True,
                                    with_std=True)

# Execute ML-Init to add the require attributes to the transformer object
# Op and Name will be initialized automatically
standard_scaler_tf.mlinit(prior_tf=feature_extractor_tf,
                          output_features='scaled_continuous_features')

But ran into the following error:

---------------------------------------------------------------------------

AttributeError: 'function' object has no attribute 'im_class'

Any suggestions?

AirBnb price regression example breaks due to the same error.
