How to use the python bindings on DietPi?

Jeffrey · August 31, 2022, 7:29pm

The author recommends DietPi to get the best performance out of an rpi-rgb-led-matrix setup so I have downloaded this OS and installed to a test SD card on a RPI4.

I have installed Python3 using the DietPi optimized software installation system and I have installed rpi-rgb-led-matrix both directly using the included setup.py and by using the script provided by Adafruit (link) and yet whenever I try to run my python scripts (which work on Raspian Lite), I get the error 'ModuleNotFoundError: No module named ‘rgbmatrix’.

I cannot figure out how to get this library working on DietPi. Any help would be gratefully received.

I don’t use python, but this looks like you need to install the rpi-rgb-panel bindings in your pythonpath

And modify your Python path to point it to the directory that you built the python bindings in…

          import sys
          import traceback
          
          
from argparse import ArgumentParser
          from datetime import datetime
          from dotenv import load_dotenv, find_dotenv
          from pygame.locals import QUIT, DOUBLEBUF, FULLSCREEN
          
          
load_dotenv(find_dotenv())
          
          
sys.path.append(
              os.path.abspath(
                  os.path.dirname(__file__) + "/../../lib/rpi-rgb-led-matrix/bindings/python"
              )
          )
          
          
from app.config import (
              matrix_options,
              DEBUG,
              PROFILING,
              GUI_ENABLED,
