dm_control

我对这个包的功能很感兴趣，尝试了一下。然而它的Stars只有1000+，质量不容乐观。

安装步骤按 README 中的 Installation and requirements 即可。

MuJoCo Pro 2.00的安装：https://blog.csdn.net/hizcard/article/details/86585217

dm_control内部存在MuJoCo的应用代码，因此不需要MuJoCo-py。

如果自定义了MuJoCo路径，需要在安装dm_control前修改它配置文件中的默认路径(single match)。

等到安装完，我满心期待地跑起 README 中的例程时，报出了如下错误：

Traceback (most recent call last):
  File "F:/GitHub Repository/dm_control_test/main.py", line 19, in 
    viewer.launch(env, policy=random_policy, width=1920, height=1080)
  File "D:\Anaconda3\envs\py36\lib\site-packages\dm_control\viewer\__init__.py", line 42, in launch
    app = application.Application(title=title, width=width, height=height)
  File "D:\Anaconda3\envs\py36\lib\site-packages\dm_control\viewer\application.py", line 191, in __init__
    self._window = gui.RenderWindow(width, height, title)
TypeError: 'NoneType' object is not callable

直接原因是 dm_control\viewer\gui\__init__.py 中的 RenderWindow 没有被赋值。这样是不能顺利运行的，所以我把代码中的忽略异常删去，得到了新的错误：
