Tensor-based RL Baseline Agent for CivRealm

This code base includes the tensor-based baseline agent for CivRealm. More documentation about the environment can be found here.

Prepare

Install civrealm from the official CivRealm repo.

Quick Start

First install

cd freeciv-tensor-baseline
pip install -e .

then run the training script

cd examples
./train.sh # or python train.py

Fullgame

Edit freeciv-tensor-baseline/civtensor/configs/envs_cfgs/freeciv_tensor_env.yaml

Change task_name to fullgame

task_name: fullgame

Minigame

Run all minitasks

freeciv-tensor-baseline/examples/run.py will run all minitasks specified in examples/run_configs including $12\text{ types}\times 3\text{ levels} = 36 \text{ runs}$

cd exmaples
python run.py --webdir $civrealm-dir

where $civrealm-dir should specify the path of your local civrealm repo.

Expreiment results are in

freeciv-tensor-baseline/examples/results 

To view your results on tensorboard, alter the following script to match your path structure and run

cd examples/results/freeciv_tensor_env/$game_type/ppo/installtest/seed-XXXXXXXXX
# where $game_type = fullgame or minitask
tensorboard logs/

then the results should be visible in the browser.

Single Run

Edit freeciv-tensor-baseline/civtensor/configs/envs_cfgs/freeciv_tensor_env.yaml

Change task_name to random_minitask or any task name in the list of MinitaskType.list()

# copied from freeciv_minitask_env.py
MT_DEVELOPMENT_BUILD_CITY = "development_build_city"
MT_DEVELOPMENT_CITYTILE_WONDER = "development_citytile_wonder"
MT_BATTLE_ANCIENT = "battle_ancient_era"
MT_BATTLE_INDUSTRY = "battle_industry_era"
MT_BATTLE_INFO = "battle_info_era"
MT_BATTLE_MEDIEVAL = "battle_medieval"
MT_BATTLE_MODERN = "battle_modern_era"
MT_BATTLE_NAVAL_MODERN = "battle_naval_modern"
MT_BATTLE_NAVAL = "battle_naval"
MT_BATTLE_ATTACK_CITY = "battle_attack_city"
MT_BATTLE_DEFEND_CITY = "battle_defend_city"
MT_DIPLOMACY_TRADE_TECH = "diplomacy_trade_tech"

task_name: development_build_city # or random_minitask to randomly sample a minitask

You may optionally specify difficulty level and ids for minitask.

task_name: development_build_city easy 100 # type level id 
# unspecified fields would be randomly sampled 

Customize

Training parameters could be adjusted in freeciv-tensor-baseline/civtensor/configs/algos_cfgs/ppo.yaml

For training minitask tensor baseline, we used the following default setting:

seed:
  # whether to use the specified seed
  seed_specify: False
  # seed
  seed: None
train:
  # number of parallel environments for training data collection
  n_rollout_threads: 8
  # number of total training steps
  num_env_steps: 20000
  # number of steps per environment per training data collection
  episode_length: 125
  # logging interval
  log_interval: 1
