使用mujoco为MuJoCo物理库绑定Python
我想使用MuJoCo（http://www.mujoco.org/），一个使用python绑定的高级物理模拟器（https://github.com/openai/mujoco-py）。
我有我的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
但是，只要我想用下面的简单代码导入libray，
import mujoco_py
我收到以下错误消息。

我在使用MuJoCo 1.31 64位的Windows 7 64位上使用Python 3.5.1 64位。
我猜想这个问题是由于某种不兼容性的原因，我还尝试使用32位MuJoCo 1.31的Python 3.5.2 32位。 甚至，我尝试了非逻辑的32位Python和64位的MuJoCo组合，反之亦然。
MuJoCo库中已编译的示例“simulate.exe”非常完美。 所以，我想我的64位MuJoCo库没有问题。 （顺便说一句，它的32位版本不能在64位Windows上运行）
因此，将C ++库加载到Python时可能会出现问题。 我进行了调试，至少检查了mujoco_py库中的Python代码尝试从正确的路径加载“mujoco131.lib”（不是“mujoco131.dll”）。 然后发生错误，代码无法进一步运行。
我愿意接受任何意见和建议。
干杯! 祝你有愉快的一天！
尝试编辑mjlib.py ，用加载器中的"bin/mujoco131.dll"替换"bin/mujoco131.lib" 。
我还必须在platname_targdir.py明确指定platname = "win"
