The "pynomo" version you have installed may have been developped for
Python 2 and not run in "python3".

In Python 2, you have implicit relative imports.
As an example, it allows modules in the package "pynomo"
to use "import nomo_wrapper" to import the submodule "nomo_wrapper".
Python 3 has discarded implicit relative imports. In
the example above, "import nomo_wrapper" must become
"from . import nomo_wrapper" (explicit relative import)
or "import pynomo.nomo_wrapper as nomo_wrapper" (absolute import).

For the time being, you still find many packages which run
only under Python 2. Failing relative imports or syntax errors
are a frequent indication towards this.
