# **TRPO** Agent playing **Humanoid-v3**
This is a trained model of a **TRPO** agent playing **Humanoid-v3**
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 trpo --env Humanoid-v3 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo trpo --env Humanoid-v3  -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 trpo --env Humanoid-v3 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo trpo --env Humanoid-v3  -f logs/
```

## Training (with the RL Zoo)
```
python -m rl_zoo3.train --algo trpo --env Humanoid-v3 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo trpo --env Humanoid-v3 -f logs/ -orga qgallouedec
```

## Hyperparameters
```python

             ('cg_damping', 0.1),
