hi - first time trying to install this and i am experiencing this error:

sudo python3 main.py --led-gpio-mapping="adafruit-hat" --led-slowdown-gpio=2
Traceback (most recent call last):
File "/home/pi/led-stock-ticker/main.py", line 7, in
from rgbmatrix import RGBMatrix
ModuleNotFoundError: No module named 'rgbmatrix'

any help is appreciated.

thank you

Were there any errors shown after running the install.sh script? This script takes care of installing the rgbmatrix library.
