A problem about OpenAI!

[hychong1997]

Hi!
I am trying to use the OpenAI following the procedure on https://www.scrimmagesim.org/sphinx/html/tutorials/openai-plugin.html.
I use Ubuntu 18.04. All of the files are built successfully.
However when i ran "python my_openai.py", it showed :
Traceback (most recent call last):
File "/home/hyc/scrimmage/scrimmage/env/lib/python3.6/site-packages/gym/envs/registration.py", line 121, in spec
return self.env_specs[id]
KeyError: 'scrimmage-v0'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "my_openai.py", line 16, in test_openai
env = gym.make('scrimmage-v0')
File "/home/hyc/scrimmage/scrimmage/env/lib/python3.6/site-packages/gym/envs/registration.py", line 145, in make

TypeError: init(): incompatible constructor arguments. The following argument types are supported:
1. scrimmage.bindings.py_bindings.ScrimmageOpenAIEnv(mission_file: str, combine_actors: bool=False, global_sensor: bool=False, static_obs_space: bool=True, timestep: float=-1)

Invoked with: kwargs: enable_gui=False, mission_file='/home/hyc/scrimmage/my-scrimmage-plugins/missions/openai_mission.xml'

Could you give me any suggestions and instructions.
Sincerely.

I haven't seen this error before, but I'm happy to make some suggestions. Have you tried removing enable_gui=False? It doesn't seem to be listed in the TypeError. Also, can you tell me what version of gym you're using in case this is something we need to update to work with a newer version of OpenAI Gym.
