【问题描述】：

我在 windows 10 x64 上使用 openAI gym，通过 windows 远程桌面 使用 python 3.6.7 我成功安装了 atari-py 和 mujoco-py，但是当我尝试运行这段代码时。

import gym

env = gym.make('Humanoid-v2')

for i_episode in range(100):
    env.reset()
    for t in range(100):
        env.render()
        action = env.action_space.sample()
        observation, reward, done, info = env.step(action)
        if done:
            print("Episode finished after {} timesteps".format(t+1))
            break

我收到了这个错误：

GLFW error (code %d): %s 65544 b'Vulkan: Failed to query instance extension count: The requested version of Vulkan is not supported by the driver or is otherwise incompatible'
Creating window glfw
GLFW error (code %d): %s 65542 b'WGL: The driver does not appear to support OpenGL'

【问题讨论】：

GLFW error (code %d): %s 65542 b'WGL: The driver does not appear to support OpenGL' 检查您的图形驱动程序到底支持什么。
@Nadir，谢谢兄弟。我有 GTX 1070ti，它支持最高 4.5 的 OpenGL，可能是因为 PyOpenGL 包（3.1.0）只支持最高 OpenGL 4.4。

【解决方案1】：

OpenGL over WindowsRemote 在 1.1 之后的 OpenGL 版本的 NVIDIA GPU 上不受支持。是否有关于存在什么解决方法的文章： Current state and solutions for OpenGL over Windows Remote

要在伤口上加盐：您可以启动 opengl 上下文，然后通过 WindowsRemote 连接。但是如果没有变通方法，直接在会话中启动是不可能的。
