tbpy如何查询历史数据

# encoding utf-8 import tbpy import sys from datetime import datetime import numpy as np import pandas as pd if __name__ == '__main__': init = tbpy.init('tbquant3') if init is False: print('init fail.') sys.exit() print('init success.') # get quote test # get history kline by count # get_history_n(symbol, frequency, count, fields: list=None, timeout='30s') history1 = tbpy.get_history_n(symbol='rb000.SHFE', frequency='1d', count=5) print(1) print(history1) history2 = tbpy.get_history_n(symbol=['rb000.SHFE', 'a9000.DCE'], frequency='1m', count=10, fields=['open', 'high', 'time'], timeout='10s') print(2) print(history2) # get history kline by begin/end time # get_history(symbol, frequency, begin_time: datetime, end_time: datetime, fields: list=None, timeout='30s') history3 = tbpy.get_history(symbol='rb000.SHFE', frequency='1d', begin_time=datetime(2025, 11, 7), end_time=datetime(2025, 11, 11), flag=tbpy.QuoteFlag.RolloverBackWard) print(3) print(history3) # get_quote(symbol) tick4 = tbpy.get_current_tick(symbol='IF000.CFFEX') print(4) print(tick4) tick5 = tbpy.get_current_tick(symbol=['IF000.CFFEX', 'a9000.DCE', 'CF000.CZCE']) print(5) print(tick5) df = pd.DataFrame(history1) df.set_index('time', inplace=True)请问为什么查询不到数据，tbquant3正常打开。
