# Model parameters trained with `i-DQN` and `i-IQN`
This repository contains the model parameters trained with `i-DQN` on [56 Atari games](#i-DQN_games) and trained with `i-IQN` on [20 Atari games](#i-IQN_games) 🎮. 5 seeds are available for each configuration which makes a total of 380 available models 📈.

The [evaluate.ipynb](./evaluate.ipynb) notebook contains a minimal example to evaluate to model parameters 🧑‍🏫. It uses JAX 🚀. The hyperparameters used during training are reported in [config.json](./config.json) 🔧.

ps: The set of [20 Atari games](#i-DQN_games) is included in the set of [56 Atari games](#i-IQN_games).

## User installation
Python 3.10 is recommended. Create a Python virtual environment, activate it, update pip and install the package and its dependencies in editable mode:
```bash
python3.10 -m venv env
source env/bin/activate
pip install --upgrade pip
pip install numpy==1.23.5  # to avoid numpy==2.XX
pip install -r requirements.txt
pip install --upgrade "jax[cuda12_pip]==0.4.13" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
```
