Python SUDS issue

[VGNU Linux]

Hi Guys,
I am pretty new to web services.
After some googling found that python suds is a suitable module to create
web service client. I am trying to create a client but its giving me an
error which is quite confusing for me.

Here is my code:
from suds.client import Client
wsdlurl = 'https://46.51.221.138/PBExternalServices/v1/soap?wsdl'
client = Client(wsdlurl)
print client

And following is the error that occurs on trying to print client.
Traceback (most recent call last):
  File "trysuds.py", line 3, in <module>
    client = Client(wsdlurl)
  File "C:\Python25\Lib\site-packages\suds\client.py", line 112, in __init__
    self.wsdl = reader.open(url)
  File "C:\Python25\Lib\site-packages\suds\reader.py", line 152, in open
    d = self.fn(url, self.options)
  File "C:\Python25\Lib\site-packages\suds\wsdl.py", line 159, in __init__
    self.build_schema()
  File "C:\Python25\Lib\site-packages\suds\wsdl.py", line 220, in
build_schema
    self.schema = container.load(self.options)
  File "C:\Python25\Lib\site-packages\suds\xsd\schema.py", line 95, in load
    child.dereference()
  File "C:\Python25\Lib\site-packages\suds\xsd\schema.py", line 323, in
dereference
    midx, deps = x.dependencies()
  File "C:\Python25\Lib\site-packages\suds\xsd\sxbasic.py", line 469, in
dependencies
    raise TypeNotFound(self.ref)
suds.TypeNotFound: Type not found: '(GetAccountBalanceFaultResponse,
http://www.payback.net/lmsglobal/xsd/v1/types, )'

Appreciate your help.
Thanks in advance,
VGNU
