If you plan on running your deployed LabVIEW on the Pi using a SSH connection from a remote machine, make sure to setup X11 forwarding from your Pi to your development machine. This link is a good one if you are using Putty for your SSH, but this is a fairly easy to find Google topic for other SSH clients. If you fail to do that, you may see an error that will look like “_tkinter.TclError: no display name and no $DISPLAY environment variable”. This link has a good explanation as to why you need to do that.
