当我运行代码时，出现了下面的“python int too large to convert to sqlite integer”错误。我是psql的初学者。
代码：import pandas as pd import numpy as np import pandasql as psql from pandasql import sqldf

T900_file = r'K:\myfile.xlsx'
df1 = pd.read_excel(T900_file)

T1000 = psql.sqldf("""Select Date
                            ,UP_Cust_Num
                            ,UP_Cust_Name
                            ,sum(Utilized_FVO)  as FVO
                            ,avg(UP_Generation) as UP_Gen
                      from df1
                      Group by Date, UP_Cust_Num, UP_Cust_Name""")

错误必须与聚合有关。如何解决错误？任何帮助都将不胜感激。
