MuJoCo 在 Windows 10 上構建錯誤

Question

運行 Windows 10 Python 3.10，嘗試運行 OpenAI Gym 人形示例： humanoid.py

懷疑與 Cython 和 C 編譯器有關。

Answer 1

Gym 最近改變了他們在新環境中依賴 MuJoCo 的方式，這種方式不需要 mujoco-py 和 cython。

我不知道您的具體問題是什么，但如果您願意切換到新版本的環境（ humanoid_v4.py ），您可能不會遇到它。

請參閱Open AI README中的詳細信息：

要安裝最新的健身房 MuJoCo 環境的依賴項，請使用pip install gym[mujoco]
