# **A2C** Agent playing **MountainCar-v0**
This is a trained model of a **A2C** agent playing **MountainCar-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
SB3: https://github.com/DLR-RM/stable-baselines3
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 MountainCar-v0 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo a2c --env MountainCar-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 a2c --env MountainCar-v0 -orga qgallouedec -f logs/
python -m rl_zoo3.enjoy --algo a2c --env MountainCar-v0 -f logs/
```
## Training (with the RL Zoo)
```
python -m rl_zoo3.train --algo a2c --env MountainCar-v0 -f logs/
# Upload the model and generate video (when possible)
python -m rl_zoo3.push_to_hub --algo a2c --env MountainCar-v0 -f logs/ -orga qgallouedec
```
## Hyperparameters
```python
OrderedDict([('ent_coef', 0.0),
('n_envs', 16),
('n_timesteps', 1000000.0),
('normalize', True),
('policy', 'MlpPolicy'),
('normalize_kwargs', {'norm_obs': True, 'norm_reward': False})])
```
