Question

我当前在Visual Studio代码1.25.1中使用Python 3.5.4

我正在尝试使用openai体育馆，并试图使用MuJoCo软件包。我已经在MuJoCo成功注册了一个帐户，并为win64下载了mjpro150。使用openai提供的最基本的示例，我使用以下代码来尝试启动Humanoid-v2任务：

import gym
env = gym.make('Humanoid-v2')
for i_episode in range(20):
observation = env.reset()
for t in range(100):
    env.render()
    print(observation)
    action = env.action_space.sample()
    observation, reward, done, info = env.step(action)
    if done:
        print("Episode finished after {} timesteps".format(t+1))
        break

在终端上运行后，我收到输出：

Exception: Please add mujoco library to your PATH:
set Path=C:\Users\Adam9\.mujoco\mjpro150\bin;%Path%

我要解决的问题是“异常：请将mujoco库添加到您的PATH：”，它是builder.py第78行的输出，对于上下文行64-81是：

lib_path = os.path.join(mjpro_path, "bin")
if sys.platform == 'darwin':
    Builder = MacExtensionBuilder
elif sys.platform == 'linux':
    _ensure_set_env_var("LD_LIBRARY_PATH", lib_path)
    if os.getenv('MUJOCO_PY_FORCE_CPU') is None and get_nvidia_lib_dir() is 
    not None:
        _ensure_set_env_var("LD_LIBRARY_PATH", get_nvidia_lib_dir())
        Builder = LinuxGPUExtensionBuilder
    else:
        Builder = LinuxCPUExtensionBuilder
elif sys.platform.startswith("win"):
    var = "Path"
    if var not in os.environ or lib_path not in os.environ[var].split(";"):
        raise Exception("Please add mujoco library to your PATH:\n"
                        "set %s=%s;%%%s%%" % (var, lib_path, var))
    Builder = WindowsExtensionBuilder
else:
    raise RuntimeError("Unsupported platform %s" % sys.platform)

我已经在用户（Adam9）中添加了.mujoco文件夹，并在bin文件夹中添加了mjkey.txt。我还在Python文件夹的site-packages文件夹中包含了mujoco库的路径。添加的所有路径为：

C：\ Users \ Adam9.mujoco \ mjpro150 \ bin

C：\ Users \ Adam9.mujoco \ mjpro150 \ bin;％Path％

C：\ Python35 \ Lib \ site-packages \ mujoco_py \ mujoco \ bin

C：\ Python35 \ Lib \ site-packages \ mujoco_py \ mujoco

C：\ Python35 \ Lib \ site-packages \ mujoco_py

C：\ Python35 \ Lib \ site-packages \ Cython

所有路径都同时反映在用户变量和系统变量中。列出的“ mujoco”文件夹是从MuJoCo网站下载的“ mjpro150”文件夹的重命名。我应该如何解决这个问题？
