求助：qs.ths_index_member(sector)调用该函数抛出错误：ValueError: No tables found？是什么原因，如何解决？

[h6arry]

import pandas as pd
import qstock as qs

sector_industry_stocks = {}
sector_industry_lists = qs.ths_index_name('行业') #该函数调用正常，获得行业板块有300多个
for sector in sector_industry_lists:
sector_industry_stocks[sector] = qs.ths_index_member(sector) #调用该函数抛出ValueError错误，具体如下：
sector_industry_stocks.head()

错误：

这个框架，获取数据都是免费吗？

我也遇到同样的错误，估计同花顺网站的数据位置变了
