FactorAnalyzer cannot update base_df

[Guocode]

when i try to use df1 and df2, it seems not work

        fa1 = FactorAnalyzer(
            base_df=df1,
            trade_date_col='datetime',
            symbol_col='symbol',
            price_col='close',
            factor_name='factor',
        )
        
        fa1.run()

        fa2 = FactorAnalyzer(
            base_df=df2,
            trade_date_col='datetime',
            symbol_col='symbol',
            price_col='close',
            factor_name='factor',
        )
        
        fa2.run()

the results are always the same. my os is windows

FA = FactorAnalyzer(base_df=df,
trade_date_col='datetime',
symbol_col='symbol',
price_col='close',
factor_name='alpha_003')
FA.run()
FA.create_long_return_sheet()
FA.create_long_short_return_sheet()
FA.create_short_return_sheet()
FA.create_single_fac_ic_sheet()

you may try these functions or it will not be graphs there if you only use .run()
