# (CleanRL) **PPO** Agent Playing **HalfCheetah-v4**
This is a trained model of a PPO agent playing HalfCheetah-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 HalfCheetah-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/HalfCheetah-v4-ppo_fix_continuous_action-seed2/raw/main/ppo_fix_continuous_action.py
curl -OL https://huggingface.co/sdpkjc/HalfCheetah-v4-ppo_fix_continuous_action-seed2/raw/main/pyproject.toml
curl -OL https://huggingface.co/sdpkjc/HalfCheetah-v4-ppo_fix_continuous_action-seed2/raw/main/poetry.lock
poetry install --all-extras
python ppo_fix_continuous_action.py --save-model --upload-model --hf-entity sdpkjc --env-id HalfCheetah-v4 --seed 2 --track
```
