Are Reinforcement Learning Frameworks Permitted?

Hi,
I am new to these sorts of competitions. I have mostly just used tensorflow to implement reinforcement learning algorithms while learning, however I have found several frameworks such as RLlib (ray) to be useful. While these frameworks are great for testing, I was wondering if we are allowed to use them in submission code. I did not see any rules which mentioned this.

Thanks

Of course! You are free to use what ever open-source code you would like in developing your agent =)
