今天在使用DQN来模拟仿真环境SUMO的时候出现了下面的错误：

Invalid MIT-MAGIC-COOKIE-1 keyFXApp::openDisplay: unable to open display :0.0
/usr/share/sumo/tools/traci/main.py:155: UserWarning: Could not connect to TraCI server using port 33253 (TraCI server already finished). Retrying with different port.

我运行的代码为https://github.com/Sanillala/AI-Traffic-Control-System

然后就很烦，我是用visual studio code远程连接，然后运行的，后面发现我没有开图形界面的原因，然后我就打开了ubuntu的图形化界面运行，发现问题就没有了。
