|
本软件包是基于 [JAX](https://github.com/jax-ml/jax) 对 [MuJoCo 物理引擎](https://github.com/google-deepmind/mujoco) 的重新实现。该库由 Google DeepMind 开发和维护，并与 MuJoCo 本身的最新进展保持同步。
|
|
|
|
`mujoco-mjx` 软件包在 API 上与 MuJoCo 兼容，但缺少 MuJoCo 中的某些功能。有关功能特性的对齐情况，请参阅我们的[官方文档](https://mujoco.readthedocs.io/en/stable/mjx.html)。
|
|
|
|
## 安装
|
|
|
|
推荐通过 [PyPI](https://pypi.org/project/mujoco-mjx/) 安装本软件包：
|
|
|
|
```sh
|
|
pip install mujoco-mjx
|
|
```
|
|
|
|
## 使用说明
|
|
|
|
安装完成后，可以通过 `from mujoco import mjx` 导入该包。有关该包 API 的更多详细信息，请参阅我们的[官方文档](https://mujoco.readthedocs.io/en/stable/mjx.html)。
|
|
|
|
我们建议查阅教程 Notebook，它介绍了 MJX API 并在数分钟内训练一个强化学习策略：

|
|
|
|
## 版本规范
|
|
|
|
版本号的 `major.minor.micro` 部分与该库所基于的 MuJoCo 版本保持一致。可选地，如果我们发布了针对同一 MuJoCo 版本的 MJX 自身更新，则会添加 `.postN` 后缀，例如 `3.0.1.post2` 表示针对 MuJoCo 3.0.1 的 MJX 第二次更新。
