Implemented DQN [3] and A3C [4] algorithm for ViZDoom [1] and DeepMind Lab [2] environments.

Small network on small screen resolution trained relatively fast on simple maps:

• DQN on 1 GPU: ~ 5 minutes on ViZDoom map simpler_basic.
• DQN on 1 GPU: ~ 5 hours on DeepMind Lab map seekavoid_arena_01.
• A3C on 1 CPU, 3 threads: ~13 minutes on ViZDoom map simpler_basic.
• A3C on 1 GPU, 3 workers: ~8 minutes on ViZDoom map simpler_basic.

DQN, ViZDoom map simpler_basic

DQN, DeepMind Lab map seekavoid_arena_01

• DeepMind Lab

ViZDoom

• Install ViZDoom and other dependencies
• Set path to it in variable vizdoom_path
• Set variable lab to False
• Set path to rl_3d in path_work_dir
• Run:
  • DQN: ./agent_dqn.py --gpu 0
  • A3C: ./agent_a3c.py

DeepMind Lab

• Install DeepMind Lab and other dependencies
• Set variable lab to True
• Set path to rl_3d in path_work_dir
• For now I used DeepMind Lab build and run system through bazel, so add build rule to lab_path/BUILD (change path_work_dir to your rl_3d path):

py_binary(
    name = "agent_dqn",
    srcs = ["*path_work_dir*/agent_dqn.py"],
    data = [":deepmind_lab.so"],
    main = "*path_work_dir*/agent_dqn.py",
)

py_binary(
    name = "agent_a3c",
    srcs = ["*path_work_dir*/agent_a3c.py"],
    data = [":deepmind_lab.so"],
    main = "*path_work_dir*/agent_a3c.py",
)

• From lab_path run:
  • DQN: bazel run :agent_dqn -- --gpu 0
  • A3C: bazel run :agent_a3c

A3C is a little bit tricky algorithm and there are a lot of it's implementations already. So as reference I used implementation by Arthur Juliani.
