# **ARS** Agent playing **HalfCheetahBulletEnv-v0**
This is a trained model of a **ARS** agent playing **HalfCheetahBulletEnv-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 ars --env HalfCheetahBulletEnv-v0 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo ars --env HalfCheetahBulletEnv-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 ars --env HalfCheetahBulletEnv-v0 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo ars --env HalfCheetahBulletEnv-v0 -f logs/
```
## Training (with the RL Zoo)
```
python -m rl_zoo3.train --algo ars --env HalfCheetahBulletEnv-v0 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo ars --env HalfCheetahBulletEnv-v0 -f logs/ -orga qgallouedec
```
## Hyperparameters
```python
OrderedDict([('alive_bonus_offset', 0),
('delta_std', 0.03),
('learning_rate', 0.02),
('n_delta', 8),
('n_envs', 1),
('n_timesteps', 75000000.0),
('n_top', 8),
('normalize', 'dict(norm_obs=True, norm_reward=False)'),
('policy', 'MlpPolicy'),
('policy_kwargs', 'dict(net_arch=[64, 64])'),
('zero_policy', False),
('normalize_kwargs', {'norm_obs': True, 'norm_reward': False})])
```
