creating the environment

[DeenaAbusham]

when I try to execute this line:
env.render()
I get this error:
/usr/local/lib/python3.7/dist-packages/pyglet/canvas/xlib.py in init(self, name, x_screen)
121 self._display = xlib.XOpenDisplay(name)
122 if not self._display:
--> 123 raise NoSuchDisplayException('Cannot connect to "%s"' % name)
124
125 screen_count = xlib.XScreenCount(self._display)

NoSuchDisplayException: Cannot connect to "None"

This error is generated outside of our code. I think the rendering library is not finding a screen. Are you running this on a server or locally? If you are running it on a server I would suggest disabling rendering.
