playground with missing attribute

AttributeError: module 'gym.spaces' has no attribute 'prng‘

Did this happen when you were trying to install the project dependencies or when trying to run a battle? Anything to give more context, so we can try to reproduce the problem or help you more.

thanks for the reply. This happens when I try to use the Playground.ipynb in the notebook

Can you check your version of gym? Are you using our requirements.txt to install everything?

OpenAI gym removed prng on Jan 30th. I'm also on 0.12.0 and encountered this error when attempting to use env.seed()

https://github.com/openai/gym/commit/6497c9f1c6e43066c8945f02ed3ed4d234f45dc1#diff-b6bcac3b96f9b9aa1c6be76eaa754d20

I think we can just get rid of this then as they are relying on gym.utils's seeding. Adjusted in 95c728b.
