Trimesh show method returns AttributeError


I am using the Python trimesh library to manipulate and analyse triangular meshes. Calling the show() method returns an AttributeError :

import trimesh
mesh = trimesh.load_mesh("myfile.stl")
mesh.show()

Traceback (most recent call last):
  File "/Users/cg/anaconda/lib/python2.7/site-packages/IPython/core/interactiveshell.py", line 2881, in run_code

    window_frame = self._nswindow.frame()
AttributeError: 'NoneType' object has no attribute 'frame'

I am using Python 2.7.11 and OSX 10.11. Has anyone encountered a similar problem?
