# **SAC** Agent playing **Walker2DBulletEnv-v0**
This is a trained model of a **SAC** agent playing **Walker2DBulletEnv-v0**
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 sac --env Walker2DBulletEnv-v0 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo sac --env Walker2DBulletEnv-v0  -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 sac --env Walker2DBulletEnv-v0 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo sac --env Walker2DBulletEnv-v0  -f logs/
```

## Training (with the RL Zoo)
```
python -m rl_zoo3.train --algo sac --env Walker2DBulletEnv-v0 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo sac --env Walker2DBulletEnv-v0 -f logs/ -orga qgallouedec
```

## Hyperparameters
```python
OrderedDict([('batch_size', 256),
             ('buffer_size', 300000),
             ('ent_coef', 'auto'),
             ('gamma', 0.98),
             ('gradient_steps', 8),
             ('learning_rate', 'lin_7.3e-4'),
             ('learning_starts', 10000),
             ('n_timesteps', 1000000.0),
             ('policy', 'MlpPolicy'),
             ('policy_kwargs', 'dict(log_std_init=-3, net_arch=[400, 300])'),
             ('tau', 0.02),
             ('train_freq', 8),
             ('use_sde', True),
             ('normalize', False)])
