    I followed this https://github.com/Unity-Technologies/ml-agents/blob/master/docs/Learning-Environment-Executable.md to create environment of my own.

    But when i run this

    from mlagents_envs.environment import UnityEnvironment
    env = UnityEnvironment(file_name="v1-ball-cube-game.x86_64")


    env.reset()
    behavior_names = env.behavior_spec.keys()
    print(behavior_names)
    Game window pop up and then terminal show error saying

    Traceback (most recent call last):
    File "index.py", line 6, in <module>
    behavior_names = env.behavior_spec.keys()
    AttributeError: 'UnityEnvironment' object has no attribute 'behavior_spec'

    I created environment by following https://github.com/Unity-Technologies/ml-agents/blob/master/docs/Learning-Environment-Create-New.md ( it make without brain ) and i was able to train modal by .conf file. Now i wanted to connect to python API.

    Ok I think it is due to a different version of ml-agents. Try get_behavior_spec()
