请教个 数据问题，用导入CSV的代码出现了下面的问题,谢谢！
PS C:\Users\jzz\desktop\36> python .\load_data_36.py
Traceback (most recent call last):
File "C:\Users\jzz\desktop\36\load_data_36.py", line 7, in <module> py
from vnpy.trader.database import database_manager
ImportError: cannot import name 'database_manager' from 'vnpy.trader.database'
(C:\veighna_studio\lib\site-packages\vnpy\trader\database.

找到了：改为
from vnpy.trader.database import get_database
database_manager = get_database()
