Loading MJCF and visualize with matplotlib will crash (MacOS Mojave 10.14.1). Reproduce with the following code:

from matplotlib import pyplot as plt
import numpy as np
from dm_control import mujoco
simple_MJCF = """
<mujoco>
<worldbody>
<light name ="top" pos ="0 0 1.5"/>
<geom name ="floor" type ="plane" size ="1 1 .1"/>
<body name ="box" pos ="0 0 .3" >
<joint name ="up_down" type ="slide" axis ="0 0 1"/>
<geom name ="box" type ="box" size =".2 .2 .2" rgba ="1 0 0 1"/>
<geom name ="sphere" pos =".2 .2 .2" size =".1" rgba ="0 1 0 1"/>
</body>
</worldbody>
</mujoco>
"""
physics = mujoco.Physics.from_xml_string(simple_MJCF)
pixels = physics.render()
plt.imshow(pixels)
plt.savefig('./test.png')

The error message is

The issue seems very similar to this one: google-deepmind/pysc2#2

@Xingyu-Lin Could you elaborate on how you installed things? I'm currently only able to test on macOS 10.13.6 (High Sierra), with Python 3.6 and GLFW installed through pip as documented in the README.

In my setup, if I do from matplotlib import pyplot as plt as you did in your snippet, I get the following error message:

ImportError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are using (Ana)Conda please install python.app and replace the use of 'python' with 'pythonw'. See 'Working with Matplotlib on OSX' in the Matplotlib FAQ for more information.

However, if I import matplotlib after I've created the Physics object, everything seems to work fine. (Note that I have not tried to install Python as a framework as requested by matplotlib. That might also make a difference.)

Closing since we don't have enough information to diagnose or reproduce this

I'm seeing the same crash with the following program:

import matplotlib.pyplot as plt
from dm_control import suite

plt.plot()
plt.show()

If I disable the dm_control import, the empty figure displays normally. If I leave it in, I get the following error:
