使用MuJoCo-py包为MuJoCo物理库绑定Python

我想使用MuJoCo(http://www.mujoco.org/)，一个具有python绑定的高级物理模拟器(https://github.com/openai/mujoco-py)。

我得到了我的MuJoCo许可证文件mjkey.text，并相应地将所需的路径MuJoCo_PY_mjkey_PATH、MuJoCo_PY_MJPRO_PATH添加到环境变量中。

MUJOCO_PY_MJPRO_PATH = C:DropboxPhDMuJoComjpro131
MUJOCO_PY_MJKEY_PATH = C:DropboxPhDMuJoComjpro131bin

然而，一旦我想导入带有以下简单代码的库，

import mujoco_py

我收到以下错误消息。

我在Windows 7 64位和MuJoCo 1.31 64位上使用Python 3.5.1 64位。

我猜问题是由于某种不兼容，我还尝试了Python 3.5.2 32位与MuJoCo 1.31 32位。甚至，我尝试了非逻辑的32位Python和64位MuJoCo组合，反之亦然。

MuJoCo库中已经编译好的给定示例"simulate.exe"运行良好。所以，我想我拥有的64位MuJoCo库没有问题。(顺便说一句，32位版本的不能在64位Windows上运行(

因此，将C++库加载到Python时可能会出现此问题。我调试并至少检查了mujoco_py库中的Python代码是否试图从正确的路径加载"mujoco131.lib"(但不是"mujoko131.dll"(。然后出现错误，代码无法继续运行。

我愿意接受任何意见和建议。。

干杯！祝你今天过得愉快！
