我正在调用 visikitfrontend.py来绘制 100 次迭代后的奖励。

但我得到了错误：

   Use a production WSGI server instead.

我在这里找不到问题。基本上，我正在按照教程说明进行操作。有没有人有见解？

看起来您的 IP 地址 ( localhost) 和端口号 ( 5000) 的组合已被其他一些进程使用（因为OSError: [Errno 98] Address already in use）

我认为这很可能是因为frontend.py多次运行脚本或可能在 2 个终端中运行脚本。请关闭（“退出”）所有终端，也许等待几秒钟，然后再次运行脚本。（另外，打开你的浏览器并去http://localhost:5000看看那里有什么）

如果这不起作用，您必须查看端口5000正在使用的原因。试试这些：

谁在 Mac OS X 上的给定 TCP 端口上监听？

在 Mac 上查找（并杀死）进程锁定端口 3000
