Panda3d Hello Panda error?

So I’m following the Panda3D “A Panda Hello World” tutorial and have this in a python file:

from direct.showbase.ShowBase import ShowBase

class MyApp(ShowBase):
	def __init__(self):

		#Load the environment model
		self.environ = self.loader.loadModel("models/environment")
		#Reparent the model to render.
		#Apply scale and position transforms on the model.
		self.environ.setScale(0.25, 0.25, 0.25)
		self.environ.setPos(-8, 42, 0)

app = MyApp()

However when I run it via command prompt “python” (note that I did put the name of the file in place of “filename”), I receive the following error:

Any ideas what’s wrong?

Thanks in advance!
