Features===========**1. Reproducible**| We provide algorithms that reproduce stably the results of many influential reinforcement learning algorithms.**2. Large Scale**| Ability to support high-performance parallelization of training with thousands of CPUs and multi-GPUs.**3. Reusable**| Algorithms provided in the repository can be directly adapted to new tasks by defining a forward network and training mechanism will be built automatically.**4. Extensible**| Build new algorithms quickly by inheriting the abstract class in the framework.
