我正在读写hecdss中的信息。如何为hec hms导入此库。使用python自动化hec hms模型

from hec.script import Plot, MessageBox
from hec.io import TimeSeriesContainer
from hec.io import PairedDataContainer
from hec.hecmath import TimeSeriesMath
from hec.hecmath import PairedDataMath

[ModuleNotFoundError: No module named 'hec.script][1]
