'Series' object has no attribute 'as_matrix' -- fitting

[mattou78400]

Hi,

I tried to fit a model to a pandas table, but it gave me the following error on the auto.fit function
"'Series' object has no attribute 'as_matrix'"

`dataset = pd.read_pickle(self.path_to_metadata + '/ml_dataset.pkl')
dataset.fillna(0, inplace=True)

    train_observations, test_observations = train_test_split(dataset)
    train_observations = train_observations.copy()
    test_observations = test_observations.copy()
    # List out variable types
    data_type_dict = {'numerical': list(dataset.columns.values)}
    output_var_h = 'n_h'

    # Create and fit Automater
    auto = Automater(data_type_dict=data_type_dict, output_var=output_var_h)
    auto.fit(train_observations)`

Do you know what's wrong? I followed the introduction tutorial.

Thanks!
