After installation. I am getting following error. Can you please guide what went wrong?

In [1]: import cortex

In [2]: cortex.webshow(cortex.Volume.random("S1", "fullhead"))

TypeError Traceback (most recent call last)

Ugh this looks like a version issue with configparser, which is a built-in library. I can run this in python 2.7 without problems, so that's not it. Perhaps try running pip install --upgrade configparser?
