import gym env = gym.make('GridGame-v0') Traceback (most recent call last): File "/home/xxf/gym/gym/envs/registration.py", line 143, in spec return self.env_specs[id] KeyError: 'GridGame-v0'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "", line 1, in File "/home/xxf/gym/gym/envs/registration.py", line 167, in make return registry.make(id) File "/home/xxf/gym/gym/envs/registration.py", line 118, in make spec = self.spec(id) File "/home/xxf/gym/gym/envs/registration.py", line 153, in spec raise error.UnregisteredEnv('No registered env with id: {}'.format(id)) gym.error.UnregisteredEnv: No registered env with id: GridGame-v0 您可以指点下吗？
