Something wrong with the gym render

[Lr-2002]

Hello, Thanks for your great work, It has did a lot in language work, While ,When i'm trying to run the play_wm.py, It throw the error of gym.render() need 1 positional args, while 2 were given. Then i delete the render func 'args to only self Re-run play, It throw the error of "Not Implementderror"

        return self.env.render(mode, **kwargs)

Hi, what version of gym are you using? There are often versioning issues with env.render() and env.step() arguments.

[Lr-2002]

gym == 0.22.0 pygame == 2.5.1

Hi sorry I didn't get to this, @Lr-2002 is this still an issue that you're having? It's most likely a simple change with regards to the gym environment and the extra parameters that env.render() might expect.
