Missing attribute 'RAND_LIMIT' in modules Box2D

See original GitHub issue

The following traceback is produced when running examples/tf/trpo_cartpole.py:

  File "examples/tf/trpo_cartpole.py", line 3, in <module>
    from garage.envs.box2d import CartpoleEnv
  File "/home/aigonzal/ivanWorkspace/garage/garage/envs/box2d/__init__.py", line 1, in <module>
    from garage.envs.box2d.box2d_env import Box2DEnv
  File "/home/aigonzal/ivanWorkspace/garage/garage/envs/box2d/box2d_env.py", line 9, in <module>
    from garage.envs.box2d.box2d_viewer import Box2DViewer
  File "/home/aigonzal/ivanWorkspace/garage/garage/envs/box2d/box2d_viewer.py", line 1, in <module>
    from Box2D import b2ContactListener
  File "/home/aigonzal/anaconda2/envs/garage/lib/python3.6/site-packages/Box2D/__init__.py", line 20, in <module>
    from .Box2D import *
  File "/home/aigonzal/anaconda2/envs/garage/lib/python3.6/site-packages/Box2D/Box2D.py", line 434, in <module>
    RAND_LIMIT = _Box2D.RAND_LIMIT

It seems the problem is solved by running: pip install box2d-py

We should probably keep this open until gym/box2d fix the upstream bug.
