convert from sendump to mixture_weights

[Himanshu Srivastava]

i am doing adaptaion of my custom acoustic model. i refered this link http://cmusphinx.sourceforge.net/wiki/tutorialadapt, but i need mixture_weights file for adaptation ,when i am going to convert sendump file to mixture_weights file by using command
/python sphinxtrain\python\cmusphinx\sendump.py /sendump /mixture_weights
it gives
Traceback (most recent call last):
File "sphinxtrain\python\cmusphinx\sendump.py", line 4, in <module>
import s3mixw

Not every sendump can be converted easily, tutorial says that. You need to retrain the model.
