  This paper introduces the PettingZoo library and the
  accompanying Agent Environment Cycle ("AEC") games model.
  PettingZoo is a library of diverse sets of multi-agent
  environments with a universal, elegant Python API.
  PettingZoo was developed with the goal of accelerating
  research in Multi-Agent Reinforcement Learning ("MARL"),
  by making work more interchangeable, accessible and
  reproducible akin to what OpenAI's Gym library did for
  single-agent reinforcement learning. PettingZoo's API,
  while inheriting many features of Gym, is unique amongst
  MARL APIs in that it's based around the novel AEC games
  model. We argue, in part through case studies on major
  problems in popular MARL environments, that the popular
  game models are poor conceptual models of games commonly
  used in MARL and accordingly can promote confusing bugs
  that are hard to detect, and that the AEC games model
  addresses these problems.
