python-3.x - GlfwError: 无法创建 GLFW 窗口 (windows)

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，但是当我尝试运行此代码时。

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'

解决方案

1.1 之后的 OpenGL 版本的 NVIDIA GPU 不支持 OpenGL over WindowsRemote。是否写过关于存在什么解决方法的文章： Windows Remote 上 OpenGL 的当前状态和解决方案

为伤口添加额外的盐：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，直接在会话内启动是不可能的。
