I'm having issues with the TOPs network. Most nodes does not have input/output connections. Getting this message when lauching:
Traceback (most recent call last):

Ooo, looks like there is some serious conflict going on in your system between your Houdini Python and your Maya Python. It's somehow picking up Maya's stuff. Check your paths, and environment variables like PYTHONHOME, PYTHONPATH, and maybe consider deleting your prefs?
Maya will set PATH and PYTHONPATH in process based on what it finds in its modules files (and any other envvars that the modules choose to set), although I don't think it pushes those values to the system environment by default. If for some reason the system environment has been set up to include the folders for maya modules, (or other folders with conflicting modules), those will be ahead of folders that we're adding to the python path.
