Tianshou: a Highly Modularized Deep Reinforcement Learning Library

We present Tianshou, a highly modularized python library for deep reinforcement learning (DRL) that uses PyTorch as its backend. Tianshou aims to provide building blocks to replicate common RL experiments and has officially supported more than 15 classic algorithms succinctly. To facilitate related research and prove Tianshou's reliability, we release Tianshou's benchmark of MuJoCo environments, covering 9 classic algorithms and 9/13 Mujoco tasks with state-of-the-art performance. We open-sourced Tianshou at https://github.com/thu-ml/tianshou/, which has received over 3k stars and become one of the most popular PyTorch-based DRL libraries.
