  1. What do I need for rendering images in SMARTS?

    Need x11 or a dummy of that rendering system on Linux. We recommend a decent GPU if you are training an Agent that makes use of observation’s depending on the rendering pipeline such as TopDownRGB, OGM, or DriveableGridMap.

  2. Where can I find debug logs?

    In most cases SMARTS debug logs are located at ~/.smarts. These can be helpful to diagnose problems.

  3. Exception: Could not open window.

    This may be due to some old dependencies of Panda3D. Try the following instructions to solve it.

    # Set DISPLAY
    $ vim ~/.bashrc
    $ export DISPLAY=":1"
    $ source ~/.bashrc
    # Set xorg server
    $ sudo wget -O /etc/X11/xorg.conf
    $ sudo /usr/bin/Xorg -noreset +extension GLX +extension RANDR +extension RENDER -logfile ./xdummy.log -config /etc/X11/xorg.conf $DISPLAY & 0
