I was able to build successfully, but got a bit of a snag here:

from panda3d.core import *
from direct.showbase.ShowBase import ShowBase

class Game(ShowBase):
    def __init__(self):
        """Get the game ready to play."""
        ShowBase.__init__(self)
        self.node = render
        self.model = self.loader.loadModel('smiley')
        self.model.reparentTo(self.node)
        
        shaderdata = Mat4(0, 0, 0, 0,
                          0, 0, 0, 0,
                          0, 0, 0, 0,
                          0, 0, 0, 0)
        self.model.setShaderInput('shaderdata', shaderdata)

game = Game()
game.run()
