# (CleanRL) **PPO** Agent Playing **Walker2d-v4**

This is a trained model of a PPO agent playing Walker2d-v4.
The model was trained by using [CleanRL](https://github.com/vwxyzjn/cleanrl) and the most up-to-date training code can be
found [here](https://github.com/vwxyzjn/cleanrl/blob/master/cleanrl/ppo_fix_continuous_action.py).

## Get Started

To use this model, please install the `cleanrl` package with the following command:

```
pip install "cleanrl[ppo_fix_continuous_action]"
python -m cleanrl_utils.enjoy --exp-name ppo_fix_continuous_action --env-id Walker2d-v4
```

Please refer to the [documentation](https://docs.cleanrl.dev/get-started/zoo/) for more detail.
