Running the python notebooks

` 183 env.reset = env._reset
184 env.step = env._step
--> 185 env.seed = env._seed
186 def render(mode):
187 return env._render(mode, close=False)

AttributeError: 'RidgeEnv' object has no attribute "_seed"

I'm trying out the notebooks. I'm using python2 with tensorflow 1.5, keras 2.2.2 and blender 2.79b. When running random_agent_example.ipynb, blender starts but the screens are empty. with deepQ_agent_example.ipynb the above error message is emitted.

should I checkout different branches other than the default that comes with clone?
