A problem about examples/multiagent_chainer_test_DQN.py #26

Closed magic3007 closed 5 years ago

magic3007 commented 6 years ago

When running examples/multiagent_chainer_test_DQN.py, I encountered an exception at line 68:

Traceback (most recent call last):
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\pkg_resources\__init__.py", line 2299, in resolve
    return functools.reduce(getattr, self.attrs, module)
AttributeError: module 'marlo.envs' has no attribute 'MinecraftEnv'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "multiagent_chainer_test_DQN.py", line 73, in <module>
    env = marlo.make(env_name)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\marlo\__init__.py", line 89, in make
    env = gym.make(env_key)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 167, in make
    return registry.make(id)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 119, in make
    env = spec.make()
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 85, in make
    cls = load(self._entry_point)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 14, in load
    result = entry_point.load(False)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\pkg_resources\__init__.py", line 2291, in load
    return self.resolve()
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\pkg_resources\__init__.py", line 2301, in resolve
    raise ImportError(str(exc))
ImportError: module 'marlo.envs' has no attribute 'MinecraftEnv'

To solve this problem, I tried to compare this file with those in marlo.envs. I modified this file as following(Line 66-71):

register(
    id=env_name,
    entry_point='marlo.envs:MazeRunner.MarloEnvBuilder',
    # Make sure mission xml is in the marlo/assets directory.
    kwargs={'mission_file': args.mission_file}
)

However, I came across another exception:

Traceback (most recent call last):
  File "multiagent_chainer_test_DQN.py", line 73, in <module>
    env = marlo.make(env_name)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\marlo\__init__.py", line 89, in make
    env = gym.make(env_key)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 167, in make
    return registry.make(id)
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 119, in make
    env = spec.make()
  File "C:\Users\maiji\AppData\Local\Programs\Python\Python36\lib\site-packages\gym\envs\registration.py", line 86, in make
    env = cls(**self._kwargs)
TypeError: __init__() got an unexpected keyword argument 'mission_file'

It seemed that we need to know the specified meanings of register and its parameters. I wonder if you could explain this file in detail, especially the meaning of the parameters?

@magic3007 : It looks like you are using an older version of marLo.

Can you try installing the latest version using : 

pip3 install -U marLo
spMohanty commented 6 years ago

@magic3007 : Also, I realised the chainer examples arent updated properly yet. To get started, I would recommend to just try out the simple singleagent and the multiagent examples.

magic3007 commented 6 years ago

@spMohanty I am trying to show you my previous experience: I used to install marlo by

pip3 install -U marLo

Right after that, I run examples/multiagent_chainer_test_DQN.py, but an exception happened:

Traceback (most recent call last):
  File "multiagent_chainer_test_DQN.py", line 25, in <module>
    from marlo.multiagent import start_agents
ModuleNotFoundError: No module named 'marlo.multiagent'

I was considering that maybe it wasn't the latest version. Actually, I found marlo/multiagent.pyon github:

https://github.com/crowdAI/marLo/commit/1ab1a179382ad4b3cd15dfaea3f624b49b26256d

Maybe the version installed by pip3 isn't the latest?

The examples should have been updated on Master already. Closing this until further notice.

I'm having several issues with the examples.
