# **A2C** Agent playing **ALE/Pacman-v5**
This is a trained model of a **A2C** agent playing **ALE/Pacman-v5**
using the [stable-baselines3 library](https://github.com/DLR-RM/stable-baselines3)
and the [RL Zoo](https://github.com/DLR-RM/rl-baselines3-zoo).

The RL Zoo is a training framework for Stable Baselines3
reinforcement learning agents,
with hyperparameter optimization and pre-trained agents included.

## Usage (with SB3 RL Zoo)

RL Zoo: https://github.com/DLR-RM/rl-baselines3-zoo<br/>
SB3: https://github.com/DLR-RM/stable-baselines3<br/>
SB3 Contrib: https://github.com/Stable-Baselines-Team/stable-baselines3-contrib

Install the RL Zoo (with SB3 and SB3-Contrib):
```bash
pip install rl_zoo3
```

```
# Download model and save it into the logs/ folder
python -m rl_zoo3.load_from_hub --algo a2c --env ALE/Pacman-v5 -orga alfredo-wh -f logs/
python -m rl_zoo3.enjoy --algo a2c --env ALE/Pacman-v5  -f logs/
```

If you installed the RL Zoo3 via pip (`pip install rl_zoo3`), from anywhere you can do:
```
python -m rl_zoo3.load_from_hub --algo a2c --env ALE/Pacman-v5 -orga alfredo-wh -f logs/
python -m rl_zoo3.enjoy --algo a2c --env ALE/Pacman-v5  -f logs/
```

## Training (with the RL Zoo)
```
python -m rl_zoo3.train --algo a2c --env ALE/Pacman-v5 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo a2c --env ALE/Pacman-v5 -f logs/ -orga alfredo-wh
```

## Hyperparameters
```python
OrderedDict([('env_wrapper',
              ['stable_baselines3.common.atari_wrappers.AtariWrapper']),
             ('frame_stack', 4),
             ('n_envs', 16),
             ('n_timesteps', 500000.0),
             ('policy', 'CnnPolicy'),
             ('policy_kwargs',
              'dict(optimizer_class=RMSpropTFLike, '
              'optimizer_kwargs=dict(eps=1e-5))'),
             ('vf_coef', 0.25),
             ('normalize', False)])
```

# Environment Arguments
```python
{'render_mode': 'rgb_array'}
