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

This is a trained model of a SAC 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/sac_continuous_action.py).

## Get Started

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

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

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


## Command to reproduce the training

```bash
curl -OL https://huggingface.co/sdpkjc/Walker2d-v4-sac_continuous_action-seed4/raw/main/sac_continuous_action.py
