cannot run example successfully

[ZeroAda]

Thank you for maintaining this repo. But after setting up, I find I cannot run the examples successfully.

For gym interface:

python -m vgdl.util.humanplay.play_vgdl vgdl/games/aliens_lvl0.txt

I got the error:
File "py-vgdl/vgdl/util/humanplay/play_vgdl.py", line 89, in main controller = controller_cls(env_name, args.tracedir) File "py-vgdl/vgdl/util/humanplay/human.py", line 122, in __init__ self.env.render(mode='human') File "/home/.local/share/virtualenvs/py-vgdl-OASzJMAw/lib/python3.9/site-packages/gym/wrappers/order_enforcing.py", line 47, in render raise ResetNeeded( gym.error.ResetNeeded: Cannot callenv.render()before callingenv.reset(), if this is a intended action, set disable_render_order_enforcing=Trueon the OrderEnforcer wrapper.

For pybrain interface, python examples/pybrain/gapworld.py. after fixing a few errors, I got this:

Traceback (most recent call last): File "py-vgdl/examples/pybrain/gapworld.py", line 95, in <module> test_gapworld() File "py-vgdl/examples/pybrain/gapworld.py", line 70, in test_gapworld env = VGDLPybrainEnvironment(game, GapworldObserver(game)) File "/home/.local/share/virtualenvs/py-vgdl-OASzJMAw/lib/python3.9/site-packages/vgdl/state.py", line 96, in __init__ assert issubclass(avatar.physicstype, GridPhysics) AttributeError: 'NoneType' object has no attribute 'physicstype'

I want to use vgdl to write my own games, but the guideline seems a little hard to follow. What should be the first step in this condition?

I'll appreciate it very much if anyone can help.

Hi! unfortunately, I did not continue to work on this.

It worked for me by adding self.env.reset() before line 123 in vgdl/util/human.py.
