# Diplomacy Cicero and Diplodocus



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"](https://www.science.org/doi/10.1126/science.ade9097) published in Science, November 2022.

* ["Mastering the Game of No-Press Diplomacy via Human-Regularized Reinforcement Learning and Planning"](https://arxiv.org/abs/2210.05492) accepted to ICLR 2023.



### Code

A very brief orientation:

- Most of the language modeling and generation code is in [parlai_diplomacy](parlai_diplomacy), and leverages the [ParlAI framework](https://github.com/facebookresearch/ParlAI) for running and finetuning the language models involved.

- Within the [agents](fairdiplomacy/agents) directory, the central logic for Cicero's strategic planning lives [here](fairdiplomacy/agents/br_corr_bilateral_search.py) and [here](fairdiplomacy/agents/bqre1p_agent.py). 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](fairdiplomacy/models/base_strategy_model/base_strategy_model.py), and the bulk of the training logic lives [here](fairdiplomacy/models/base_strategy_model/train_sl.py)

- The RL training code for both Cicero and Diplodocus is [here](fairdiplomacy/selfplay)

- The [conf](conf) directory contains various configs for Cicero, Diplodocus, benchmark agents, and training configs for RL.

- A separately licensed subfolder of this repo [here](fairdiplomacy_external) contains some utilities for visually rendering games, or connecting agents to be run online.



### Game info

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](https://en.wikibooks.org/wiki/Diplomacy/Rules).

To get the game's spirit, watch [some](https://www.youtube.com/c/diplostrats) [games](https://www.youtube.com/playlist?list=PLmbDtCxqXA5CyFoBmB5dJHHOHeLQ0Nd-Y) with comments.

You can play the game online on [webDiplomacy](https://webdiplomacy.net/) either against bots or humans.



### Installation



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.



```

# Clone the repo with submodules:

git clone --recursive [email protected]:facebookresearch/diplomacy_cicero.git diplomacy_cicero

cd diplomacy_cicero



# Apt installs

apt-get install -y wget bzip2 ca-certificates curl git build-essential clang-format-8 git wget cmake build-essential autoconf libtool pkg-config libgoogle-glog-dev



# Install conda

wget --quiet https://repo.anaconda.com/miniconda/Miniconda3-4.7.10-Linux-x86_64.sh -O ~/miniconda.sh

/bin/bash ~/miniconda.sh -b



# Create conda env

conda create --yes -n diplomacy_cicero python=3.7

conda activate diplomacy_cicero



# Install pytorch, pybind11

conda install --yes pytorch=1.7.1 torchvision cudatoolkit=11.0 -c pytorch

conda install --yes pybind11



# Install go for boringssl in grpc

# We have some hacky patching code for protobuf that is not guaranteed

# to work on versions other than this.

conda install --yes go protobuf=3.19.1



# Install python requirements

pip install -r requirements.txt



# Local pip installs

pip install -e ./thirdparty/github/fairinternal/postman/nest/

# NOTE: Postman here links against pytorch for tensors, for this to work you may

# need to separately have installed cuda 11 on your own.

pip install -e ./thirdparty/github/fairinternal/postman/postman/

pip install -e . -vv



# Make

make



# Run unit tests

make test_fast

```



After each pull it's recommended to run `make` to re-compile internal C++ and protobuf code.



### Downloading model files



Please email  to request the password. Then run `bash bin/download_model_files.sh `. 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](#license-for-model-weights).



### Accessing Cicero's experiment games



JSON data and visualizations for games that Cicero played in are located in [data/cicero_redacted_games](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](fairdiplomacy_external) subdirectory for details on HTML visualizations.



### Getting started



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](heyhi/README.md)



A core abstraction is an `Agent`, which is specified by an `Agent` config whose schema lives in `conf/agents.proto`.



### Simulating games between agents



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`



### Training models in RL



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.



### Other tasks

See [here](fairdiplomacy_external) for some separately-licensed code for rendering game jsons with HTML, as well as connecting agents to run on [webdiplomacy.net](https://webdiplomacy.net).



### Supervised training of baseline models

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](parlai_diplomacy) via the ParlAI framework, and on the dialogue-free side, some of the configs [conf/c02_sup_train](conf/c02_sup_train) and [train_sl.py](fairdiplomacy/models/base_strategy_model/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.



### Pre-commit hooks



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](https://github.com/psf/black) auto-formatter to format all python code.

For protobufs use `clang-format-8 conf/*.proto -i`.



### Tests



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](https://docs.pytest.org/en/stable/) commands.



To run all tests in your current directory, simply run:

```

pytest

```



To run tests from a specific file, run:

```

pytest 

```



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/

```
