Train RL agents to play Pokemon Crystal

Running the Pretrained Model Interactively 🎮

🐍 Python 3.10+ is recommended. Other versions may work but have not been tested.
You also need to install ffmpeg and have it available in the command line.

Windows Setup

Refer to this Windows Setup Guide

Linux / MacOS

1. Copy your legally obtained Pokemon Red ROM into the base directory. You can find this using google, it should be 1MB. Rename it to PokemonRed.gb if it is not already. The sha1 sum should be ea9bcae617fdf159b045185467ae58b2e4a48b9a, which you can verify by running shasum PokemonRed.gb.
2. Move into the baselines/ directory:
   cd baselines
3. Install dependencies:
   pip install -r requirements.txt
   It may be necessary in some cases to separately install the SDL libraries.
4. Run:
   python run_pretrained_interactive.py

Interact with the emulator using the arrow keys and the a and s keys (A and B buttons).
You can pause the AI's input during the game by editing agent_enabled.txt

Note: the Pokemon.gb file MUST be in the main directory and your current directory MUST be the baselines/ directory in order for this to work.

Training the Model 🏋️

10-21-23: Updated Version!

This version still needs some tuning, but it can clear the first gym in a small fraction of the time and compute resources. It can work with as few as 16 cores and ~20G of RAM. This is the place for active development and updates!

1. Previous steps 1-3
2. Run:
   python run_baseline_parallel_fast.py

Tracking Training Progress 📈

Training Broadcast

Stream your training session to a shared global game map using the Broadcast Wrapper on your environment like this:

env = StreamWrapper(
            env, 
            stream_metadata = { # All of this is part is optional
                "user": "pw", # choose your own username
                "env_id": id, # environment identifier
                "color": "#0033ff", # choose your color :)
                "extra": "", # any extra text you put here will be displayed
            }
        )

Hack on the broadcast viewing client or set up your own local stream with this repo:

Local Metrics

The current state of each game is rendered to images in the session directory.
You can track the progress in tensorboard by moving into the session directory and running:
tensorboard --logdir .
You can then navigate to localhost:6006 in your browser to view metrics.
To enable wandb integration, change use_wandb_logging in the training script to True.

Static Visualization 🐜

Map visualization code can be found in visualization/ directory.
