# **PPO** Agent playing **MountainCarContinuous-v0**
This is a trained model of a **PPO** agent playing **MountainCarContinuous-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

```
# Download model and save it into the logs/ folder
python -m utils.load_from_hub --algo ppo --env MountainCarContinuous-v0 -orga sb3 -f logs/
python enjoy --algo ppo --env MountainCarContinuous-v0  -f logs/
```

## Training (with the RL Zoo)
```
python train.py --algo ppo --env MountainCarContinuous-v0 -f logs/
# Upload the model and generate video (when possible)
python -m utils.push_to_hub --algo ppo --env MountainCarContinuous-v0 -f logs/ -orga sb3
```
