报错问题

一个小伙伴遇到问题跑来私信我，在VSCode运行强化学习代码，但是发生了报错（当时他心里瞬间凉了一大截，跑来找我求助，然后顺利帮助他解决了，顺便记录一下希望可以帮助到更多遇到这个bug不会解决的小伙伴），报错代码如下所示：

1 2	`import` `pyglet` `window` `=` `pyglet.window.Window(500,` `500)`

During handling of the above exception, another exception occurred:

报错翻译

报错信息内容翻译如下所示：

属性错误:“NoneType”对象没有属性“Window”
pyglet.canvas.xlib.NoSuch显示异常:无法连接到“None”

报错原因

报错原因：

在其他少数情况下，它不是以一种方式运行而不是以另一种方式工作的。大多数解决方案都涉及更改图形卡设置或运行X11服务器。这在这里似乎不相关，因为它似乎只与VSCode相关。

小伙伴们按照下面的方法配置vscode即可即可！！！

解决方法

这是vscode内部终端的问题，将控制台设置为launch.json中的另一个选项解决了这个问题：
