问题描述
请注意，以下描述的部分内容特定于 Python 包 mujoco_py，但问题本身很普遍。
我按照 here 和 here 中描述的步骤构建了一个容器，其中安装了 mujoco-py，使用 GPU 进行渲染。但是，当 import mujoco_py 尝试创建一些使用 GPU 渲染所需的文件/目录时，我会在 mujoco-py 什么时候收到以下错误。但是，由于文件系统变为只读，因此在构建容器后无法在容器内创建任何文件，除非这些文件将存储在 /tmp 中。此外，就我而言，将容器构建为可写不是一个选项。我还尝试通过 mujoco-py 而不是 python3 -m pip install . -e 安装 python3 setup.py install，但在执行 import mujoco_py 时遇到了其他一些类似的错误。
有没有办法更改将要创建这些文件的路径或将这些文件保留在内存中？
