 **Tianshou** ([天授](https://baike.baidu.com/item/%E5%A4%A9%E6%8E%88)) is a reinforcement learning platform based on pure PyTorch and [Gymnasium](http://github.com/Farama-Foundation/Gymnasium). Unlike other reinforcement learning libraries, which may have complex codebases,
 unfriendly high-level APIs, or are not optimized for speed, Tianshou provides a high-performance, modularized framework 
 and user-friendly interfaces for building deep reinforcement learning agents. One more aspect that sets Tianshou apart is its
