Mujoco安装，找不到二进制文件

Question

我在安装mujoco时遇到了麻烦。

我跟着https://github.com/openai/mujoco-py/issues/253的脚步走。

一切工作正常，但当我不得不运行"python examples\body_interaction.py“时，我遇到了一个问题：

Traceback (most recent call last):
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\mujoco-py\examples\body_interaction.py", line 10, in <module>
    from mujoco_py import load_model_from_xml, MjSim, MjViewer
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\__init__.py", line 2, in <module>
    init_config()
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\config.py", line 37, in init_config
    raise error.MujocoDependencyError('Found your MuJoCo license key but not binaries. Please put your binaries into ~/.mujoco/mjpro131 or set MUJOCO_PY_MJPRO_PATH. Follow the instructions on https://github.com/openai/mujoco-py for
 setup.')
mujoco_py.error.MujocoDependencyError: Found your MuJoCo license key but not binaries. Please put your binaries into ~/.mujoco/mjpro131 or set MUJOCO_PY_MJPRO_PATH. Follow the instructions on https://github.com/openai/mujoco-py for

这是我的.mujoco目录的样子：

mujoco200是我从那里下载的目录: win64的https://www.roboti.us/index.html，

下面是我的环境变量的样子：

为了解决这个问题，我尝试从there下载"mjpro131 win64“，并将其添加到环境中。变量使用名称"MUJOCO_PY_MJPRO_PATH"，但随后它给了我另一个错误：

Traceback (most recent call last):
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\mujoco-py\examples\body_interaction.py", line 10, in <module>
    from mujoco_py import load_model_from_xml, MjSim, MjViewer
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\__init__.py", line 4, in <module>
    from .mjviewer import MjViewer
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\mjviewer.py", line 7, in <module>
    from . import mjcore, mjconstants, glfw
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\mjcore.py", line 6, in <module>
    from .mjlib import mjlib
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\mjlib.py", line 21, in <module>
    mjlib = cdll.LoadLibrary(os.path.abspath(libfile))
  File "C:\Users\User\AppData\Local\Programs\Python\Python39\lib\ctypes\__init__.py", line 452, in LoadLibrary
    return self._dlltype(name)
  File "C:\Users\User\AppData\Local\Programs\Python\Python39\lib\ctypes\__init__.py", line 374, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 193] %1 n’est pas une application Win32 valide 

最后一行翻译：

OSError: [WinError 193] %1 Is not a valid win32 application.

我也尝试过win32 achive，但它给了我完全相同的错误。

我在Linux上也遇到了同样的问题。我决定下载mujoco的0.5.7版本

pip install mujoco-py==0.5.7

然后将需求更改为

click==7.0
xmltodict==0.12.0
scipy==1.3.1
gym==0.10.8
jsonnet==0.11.2
numpy
mujoco-py==0.5.7
