ImportError: cannot import name 'envs'

When I try to run the code using main.py I got the this error:

    raise error.Error('Cannot re-register id: {}'.format(id))
gym.error.Error: Cannot re-register id: MultiagentSimple-v0

I tried to install the enviroment provided, but it didn't work. Do you have any suggestions?

Hello.

Thanks for your codes, but I got some errors.

I’m using your env.py, so I renamed the env folder and changed from env import envs to import env as envs.
Is it correct?

Since I only have CPU, I change self.sess = tf.Session(config=tf.ConfigProto(log_device_placement=True)) to
self.sess = tf.Session()
But maybe this is not related to the errors.

When I ran the codes, I get such errors:

Traceback (most recent call last):

  File “xx/scalable_maddpg/maddpg.py", line 138, in action
    action[ii,:] = self.agents[ii].action(state[ii,:])
TypeError: tuple indices must be integers or slices, not tuple

I tried to solve it by changing action[ii,:] = self.agents[ii].action(state[ii,:]) to action[ii,:] = self.agents[ii].action(state[ii]), but it lead to other errors.

Do you have some idea of the errors?
Thank you.

Hello!
I have deleted the env.py from the main dictionary, but come into this error when running the main.py. Do you have any idea about this issue? Thanks a lot!
