从其他目录导入类

Question

我有：

script1.py in database/table_inserts/  #trying to import below file into
dbcrud.py in database/                 #trying to import by above file

在script1.py我有：

from ..dbcrud import set_db_setting

但此抛出错误：

   from ..dbcrud import set_db_setting
SystemError: Parent module '' not loaded, cannot perform relative import

我做错什么了？
