The viewer shows a blank 3d grid and nothing else

Operating System: MacOS

Issue #1
. ./env.sh didn't work for me. I use source env.sh instead.

Issue #2
After running the 3 terminals, I open the VNC viewer and connected. I can hear my macbook pro's fan running hard, but nothing is displayed except for the blank 3d grid. Am I supposed to see a car running on track immediately after connecting? or I have to wait for an hour or so? I don't see any errors in the 3 terminals so I supposed I set it up properly.

Sorry, I haven't worked on Deep Racer in at least 6 months. I'm betting they've changed something that impacts these instructions. The car didn't show up immediately, but should not take more than a minute to start up. Are you getting training output in the terminals even though you can't visually see the car?

This is the last lines from the sagemaker terminal:

And this is from the robomaker terminal:

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.

Sagemaker looks correct.

I'm not sure what's going on with Robomaker. I'd recommend checking here as it is much more active.
