did you already do the steps about "cross compiling for JeVois hardware", and then "installing to jevois microSD card"?
In that tutorial, first we compile and run on the host computer, using jevois-daemon running on the host.
To use jevois inventor, however, requiries that you cross-compile the module for the JeVois camera and install it on the microSD card inside the camera. JeVois inventor is just a GUI and it relies on the JeVois camera to do all the vision processing inside the camera.
