DeepRL

If you have any question or want to report a bug, please open an issue instead of emailing me directly.

Modularized implementation of popular deep RL algorithms in PyTorch.
Easy switch between toy tasks and challenging games.

Implemented algorithms:

  • (Double/Dueling/Prioritized) Deep Q-Learning (DQN)
  • Categorical DQN (C51)
  • Quantile Regression DQN (QR-DQN)
  • (Continuous/Discrete) Synchronous Advantage Actor Critic (A2C)
  • Synchronous N-Step Q-Learning (N-Step DQN)
  • Deep Deterministic Policy Gradient (DDPG)
  • Proximal Policy Optimization (PPO)
  • The Option-Critic Architecture (OC)
  • Twined Delayed DDPG (TD3)
  • ReverseRL/COF-PAC/GradientDICE/Bi-Res-DDPG/DAC/Geoff-PAC/QUOTA/ACE

The DQN agent, as well as C51 and QR-DQN, has an asynchronous actor for data generation and an asynchronous replay buffer for transferring data to GPU. Using 1 RTX 2080 Ti and 3 threads, the DQN agent runs for 10M steps (40M frames, 2.5M gradient updates) for Breakout within 6 hours.

Dependency

  • PyTorch v1.5.1
  • See Dockerfile and requirements.txt for more details
