+ # (CleanRL) **TD3** Agent Playing **HalfCheetah-v4**
25
+
26
+ This is a trained model of a TD3 agent playing HalfCheetah-v4.
27
+ The model was trained by using [CleanRL](https://github.com/vwxyzjn/cleanrl) and the most up-to-date training code can be
28
+ found [here](https://github.com/vwxyzjn/cleanrl/blob/master/cleanrl/td3_continuous_action_jax.py).
29
+
30
+ ## Get Started
31
+
32
+ To use this model, please install the `cleanrl` package with the following command:
33
+
34
+ ```
35
+ pip install "cleanrl[td3_continuous_action_jax]"
36
+ python -m cleanrl_utils.enjoy --exp-name td3_continuous_action_jax --env-id HalfCheetah-v4
37
+ ```
38
+
39
+ Please refer to the [documentation](https://docs.cleanrl.dev/get-started/zoo/) for more detail.
40
+
41
+
42
+ ## Command to reproduce the training
43
+
44
+ ```bash
