Python 2.7, dpkt, and pyvisa

Question

when I simply use this single line of code:

import dpkt

I get this error:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import dpkt
  File "C:\Python27\lib\dpkt\__init__.py", line 24, in <module>
    import ethernet
  File "C:\Python27\lib\dpkt\ethernet.py", line 128, in <module>
    __load_types()
  File "C:\Python27\lib\dpkt\ethernet.py", line 122, in __load_types
    mod = __import__(modname, g)
  File "C:\Python27\lib\dpkt\ip6.py", line 101, in <module>
    import ip
  File "C:\Python27\lib\dpkt\ip.py", line 258, in <module>
    __load_protos()
  File "C:\Python27\lib\dpkt\ip.py", line 255, in __load_protos
    IP.set_proto(v, getattr(mod, name.upper()))
AttributeError: 'module' object has no attribute 'VISA'

What could be the problem?

What version of dpkt? What environment are you running in? Im using latest dpkt on python 2.7.5 and it imports fine. — gregb212, Oct 01 '13 at 13:48

The dpkt issue page has a patch for this problem. The second patch at https://code.google.com/p/dpkt/issues/detail?id=34 fixes the import issue.
