when I run the neat_train.py use the vaeRacer.json,I get this error: Traceback (most recent call last): File "neat_train.py", line 279, in main(args)

Hey, it is necessary to render the environment (the input is the pixels screen). Are you running this on something headless (is there really no display?). If you are trying to run headless you will have to use something like xvfb.

e.g. something like this: xvfb-run -a -s "-screen 0 1400x900x24 +extension RANDR" -- <your command>

Thanks for your reply!I run this program in server,and the server hasn't monitor.So,can I use this method to run this program?Thank you very much!

Hi,I have another question want to ask?Can I change the windows,for example change windows to 640x320?Thank you very much!

It should be no problem -- but remember for the racing domain the input is the pixels, so if the virtual screen is smaller than number of pixels it will probably be a problem.
