how to import MV module

[guangshan chen]

Hi all,

I am new. I just want to run a python program.

When I run it, python can not find MV module. The follow is the error  
information:
Traceback (most recent call last):
   File "MakeCouplerRestart.py", line 22, in <module>
     import MV,struct,Numeric,string
ImportError: No module named MV

Could any one tell me how to import MV module. Where is it?

Thanks..

Guangshan
