        self.transformer = DataTransformer()
        self.transformer.fit(train_data, categorical_columns, ordinal_columns)
        train_data = self.transformer.transform(train_data)

        data_sampler = Sampler(train_data, self.transformer.output_info)

        data_dim = self.transformer.output_dim
        self.cond_generator = Cond(train_data, self.transformer.output_info)

        self.generator = Generator(

            self.gen_dim,
            data_dim

        optimizerG = optim.Adam(
            self.generator.parameters(), lr=2e-4, betas=(0.5, 0.9),
