The train goes off the rails

Flatland Challenge
#1

Hello,
Help me, please. This is normal behaviour of the train, when, during training, he was going off the rails? I think I read somewhere that the train should remain in place if the agent commits an unacceptable action

Hi @xcilog

I think this is just a rendering issue. Looking at the observation rendering in the image you posted i think the render did not redraw the new rails.

Can you please try to do env_renderer.reset() where env_renderer is the renderer you defined.

Does this resolve your issue?

Best regards
Erik

Hi @xcilog

What version of FLATland are you using - it might be a bug which was reported and fixed few days ago.
