Trimesh显示方法返回AttributeError

Question

我正在使用Python库来操作和分析三角形网格。调用show()方法将返回一个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
    exec(code_obj, self.user_global_ns, self.user_ns)
  File "<ipython-input-5-cbb52bec63cc>", line 1, in <module>
    mesh.show()
  File "/Users/cg/anaconda/lib/python2.7/site-packages/trimesh/base.py", line 1339, in show
    scene.show(**kwargs)

    viewer()

    SceneViewer(self, **kwargs)

    self.reset_view(flags=flags)

    if (self.width is not None and
  File "/Users/cg/anaconda/lib/python2.7/site-packages/pyglet/window/__init__.py", line 850, in <lambda>
    width = property(lambda self: self.get_size()[0],
  File "/Users/cg/anaconda/lib/python2.7/site-packages/pyglet/window/cocoa/__init__.py", line 398, in get_size
    window_frame = self._nswindow.frame()
AttributeError: 'NoneType' object has no attribute 'frame'

我正在使用Python2.7.11和OSX10.11。有没有人遇到过类似的问题？
