I have absolutely no knowledge of pysnmp, but from reading the error
message I'd guess that you have a '.py' somewhere where you shouldn't.
Either the filename shouldn't have a .py, or you are referring to
the thing to be loaded with a '.py' on the end of the name when you
should be omitting it.

But like I said, I'm speaking out of my hat here, since I've never
worked with pysnmp.
