ValueError: 0 is not in range

The above exception was the direct cause of the following exception:

Cannot produce here, you can change calculate_stock_spec.py line 171 to sh.600918 and debug calculate_stock_spec.py to check what is wrong with this stock

if name=='main': starttime = datetime.datetime.now() calculate_all_spec('sh.600918', 'sh.000001')

endtime = datetime.datetime.now()
print(endtime - starttime)

你现在数据库已经生成，k线数据也都抓到了，可以运行daily_update.py了，因为你run_first_time.py没有运行完，所以没有生成date.txt，可以手动在同级目录下创建一个date.txt，内容是 2020-08-25

最好还是看一看这个股票的数据有什么问题
