我已经解决了，原因是 MetaGym/metagym/quadrotor/env.py:25 文件中 try: from metagym.quadrotor.render import RenderWindow except Exception as e: print(e) # 本来没有这句 NO_DISPLAY = True

导致如果引用出错不会打印原因，我手动将原因打印出来，发现是包缺失，安装之后就能够跑了。

请问是缺少那些包呢？我遇到跟您一模一样的问题。

可否贴出具体问题描述？从上面报错看，需要确认机器上面是否有显示设备或者GUI。如果没有，建议把enable_render关掉

您好。使用的是windows。我想在命令行看一下的"Quadrotor", task="hovering_control"的渲染效果。问题在最后，请问如何解决 命令行输入如下：

from rlschool import make_env env = make_env("Quadrotor", task="hovering_control") env.reset() array([ 0.3764959 , 1.1376995 , 0.6062036 , 0. , 0. ,

  1. , 0. , 0. , -9.8 , -3.2034495 , -2.0571785 , 0.82844687, -0. , 0. , 0. ,
  2. ], dtype=float32) env.render() Traceback (most recent call last): File "", line 1, in File "D:\ProgramData\Anaconda3\envs\RFlearning\lib\site-packages\rlschool\quadrotor\env.py", line 166, in render raise RuntimeError('[Error] Cannot connect to display screen.') RuntimeError: [Error] Cannot connect to display screen.
