Auto start script not working

[jayg7800]

I'm able to get everything working properly when manually running main.py from the install folder of /home/pi/mlb-led-scoreboard, but from anywhere else, including trying to run as a service, it fails. I'm just trying to automate startup at this point. It looks like it's failing to find rgbmatrix:

I can browse to the scoreboard URL from my laptop and see that part is working fine.

My service file is as follows:
