If you run the two cases from different directories, and the current
directory is in PYTHONPATH or sys.path, and one of the directories
contains a python file named "visa.py" and the other doesn't, that
culd account for the difference in output.

Do you have access to the visa.py source code?  Can you add a simple
print statement near the top of the module so that we know the same
visa.py module is being imported in both cases?

I was more interested in the exact commands you used to run both cases,
rather than the output.
