Description

I'm trying to use the Data generator in correlated attribute mode.I tried with many datasets and everything works fine. However, for some datasets, I'm getting the following error when I run the DataGenerator:
ValueError: Length of values (757) does not match length of index (756)

Note that the DataDescriber works fine without raising an error. However, for the datasets that I weren't able to generate syntehtic data, I checked their description file, and in all of them, the number of attributes in the Bayesian network is less than the number of attributes in the whole datasets.

What I Did

Hi, I just reviewed all implementations of AbstractAttribute.generate_values_as_candidate_key(self, n), the number of generated values is set correctly. Can you give me more information about this error? For example, what is the data type of this column, is it integer, string, datetime, or SSN? Can you print out a few generated values?

BTW, is the DataSynthesizer the latest version?
