ValueError: Input train dataframe already have 0 column, consider removing it about gan-for-tabular-data

[lablebi96]

I renamed the target column from 0 to 'target' with : target = target.rename(columns={0 : "target"}) and it worked.
Thank you for helping !

Hi!

This errors comes from this function call:

def preprocess_data(self, train_df, target, test_df, ) -> Tuple[pd.DataFrame, pd.DataFrame]:
        if isinstance(train_df, pd.DataFrame) is False or isinstance(target, pd.DataFrame) is False \
                or isinstance(test_df, pd.DataFrame) is False:
            raise ValueError("Input dataframes aren't pandas dataframes: train is {}; target is ; test is {}".
                             format(type(train_df), type(target), type(test_df)))
        self.TEMP_TARGET = target.columns[0]
        if self.TEMP_TARGET in train_df.columns:
            raise ValueError(
                "Input train dataframe already have {} column, consider removing it".format(self.TEMP_TARGET))

So you actually have same named column in train dataset as you have in your target column.
Rename target column. And reopen if still error persists.
