ImportError: cannot import name 'WrapperHeader' from 'dlms'

[ghost]

I have been trying to use this but every time i run "examples/dlms_with_tcp_example.py" , i get this error:
from dlms_cosem import WrapperHeader
ImportError: cannot import name 'WrapperHeader' from 'dlms_cosem'

I tried changing dlms to dlms_cosem, but the problem still persists. Is there any other version that supports WrapperHeader?

Have you installed from source or are you installing from pypi?

Can you add the whole traceback? Seem like there is a code error but I am wondering why I have not gotten that in production?

when i installed this via pip, the version that got downloaded was a older version. I then downloaded the latest dlms-cosem version and the issue got resolved.
