This code contains checkpoints and training code for the following papers:
- "Human-Level Play in the Game of Diplomacy by Combining Language Models with Strategic Reasoning" published in Science, November 2022.
- "Mastering the Game of No-Press Diplomacy via Human-Regularized Reinforcement Learning and Planning" accepted to ICLR 2023.
A very brief orientation:
- Most of the language modeling and generation code is in parlai_diplomacy, and leverages the ParlAI framework for running and finetuning the language models involved.
- Within the agents directory, the central logic for Cicero's strategic planning lives here and here. The latter also contains the core logic for Diplodocus's strategic planning. "bqre1p" was the internal dev name for DiL-piKL, and "br_corr_bilateral" the internal dev name for Cicero's bilateral and correlated planning components.
- The dialogue-free model architectures for RL are here, and the bulk of the training logic lives here
- The RL training code for both Cicero and Diplodocus is here
- The conf directory contains various configs for Cicero, Diplodocus, benchmark agents, and training configs for RL.
- A separately licensed subfolder of this repo here contains some utilities for visually rendering games, or connecting agents to be run online.
Diplomacy is a strategic board game set in 1914 Europe. The board is divided into fifty-six land regions and nineteen sea regions. Forty-two of the land regions are divided among the seven Great Powers of the game: Austria-Hungary, England, France, Germany, Italy, Russia, and Turkey. The remaining fourteen land regions are neutral at the start of the game.
Each power controls some regions and some units. The number of the units controlled depends on the number of the controlled key regions called Supply Centers (SCs). Simply put, more SCs means more units. The goal of the game is to control more than half of all SCs by moving units into these regions and convincing other players to support you.
You can find the full rules here. To get the game's spirit, watch some games with comments. You can play the game online on webDiplomacy either against bots or humans.
Most of the code of the project implemented in Python with some parts in C++. The snippet below show how to install and build all required components within a conda environment on Ubuntu system. You would need C++ compiler with C++11 support. We use gcc 9.4.

After each pull it's recommended to run make to re-compile internal C++ and protobuf code.
Please email [email protected] to request the password. Then run bash bin/download_model_files.sh <PASSWORD>. This will download and decrypt all relevant model files into ./models. This might take awhile. Please note the model files have their own license separate from the code in this repository. More details on this can be found below.
JSON data and visualizations for games that Cicero played in are located in data/cicero_redacted_games. Only conversations with players who have consented to having their dialogue released are included. Please refer to the (separately-licensed) fairdiplomacy_external subdirectory for details on HTML visualizations.
The front-end for most tasks is run.py, which can run various tasks specified by a protobuf config. The config schema can be found at conf/conf.proto, and example configs for different tasks can be found in the conf folder. This can be used for most tasks (except training parlai models): training no-press models, comparing agents, profiling things, launching an agent on webdip, etc.
The config specification framework, called HeyHi, is explained here
A core abstraction is an Agent, which is specified by an Agent config whose schema lives in conf/agents.proto.
To simulate 1v6 games between a pair of agents, you can run the compare_agents task. For example, to play one Cicero agent as Turkey against six full-press imitation agents, you can run
python run.py --adhoc --cfg conf/c01_ag_cmp/cmp.prototxt Iagent_one=agents/cicero.prototxt Iagent_six=agents/ablations/cicero_imitation_only.prototxt power_one=TURKEY
If you don't have sufficient memory to load two agents, you can load a single agent in self-play with the use_shard_agent=1 flag:
python run.py --adhoc --cfg conf/c01_ag_cmp/cmp.prototxt Iagent_one=agents/cicero.prototxt use_shared_agent=1 power_one=TURKEY
To run the training for Cicero and/or Diplodocus:
python run.py —adhoc —cfg conf/c04_exploit/research_20221001_paper_cicero.prototxt launcher.slurm.num_gpus=256
python run.py —adhoc —cfg conf/c04_exploit/research_20221001_paper_diplodocus_high.prototxt launcher.slurm.num_gpus=256
The above training commands are designed for running on an appropriately configured Slurm cluster with a fast cross-machine shared filesystem. One can also instead pass launcher.local.use_local=true to run them on locally, e.g. on an individual 8-GPU-or-more GPU machine but training may be very slow.
See here for some separately-licensed code for rendering game jsons with HTML, as well as connecting agents to run on webdiplomacy.net.
Supervised training and/or behavioral cloning for various dialogue-conditional models as well as pre-RL baseline dialogue-free models involves some of the scripts in parlai_diplomacy via the ParlAI framework, and on the dialogue-free side, some of the configs conf/c02_sup_train and train_sl.py. However the dataset of human games and/or dialogue is NOT available here, so the relevant code and configs are likely to be of limited use. They are provided here mostly as documentation for posterity.
However, as mentioned above pre-trained models are available, and with sufficient compute power, re-running the RL on top of these pre-trained models is also possible without any external game data.
Run pre-commit install to install pre-commit hooks that will auto-format python code before commiting it.
Or you can do this manually. Use black auto-formatter to format all python code.
For protobufs use clang-format-8 conf/*.proto -i.
To run tests locally run make test.
We have 2 level of tests: fast, unit tests (run with make test_fast) and slow, integration tests (run with make test_integration).
The latter aims to use the same entry point as users do, i.e., run.py for the HeyHi part and diplom for the ParlAi.
We use pytest to run and discover tests. Some useful pytest commands.
To run all tests in your current directory, simply run:
pytest
To run tests from a specific file, run:
pytest <filepath>
To use name-based filtering to run tests, use the flag -k. For example, to only run tests with parlai in the name, run:
pytest -k parlai
For verbose testing logs, use -v:
pytest -v -k parlai
To print the output from a test or set of tests, use -s; this also allows you to set breakpoints:
pytest -s
To view the durations of all tests, run with the flag --durations=0, e.g.:
pytest --durations=0 unit_tests/
