Hi all Using 2x 16x32 panels in parallel connection as 32x32, Pi4B+ 4G Using all the instructions , successfully working examples on folders:

-examples-api-use folder -utils folder On python folder I have a problem... I am fighting with this error like most of beginners I suppose: $ sudo ./simple-square.py Traceback (most recent call last): File "./simple-square.py", line 2, in from samplebase import SampleBase File "/home/pi/display16x32/rpi-rgb-led-matrix/bindings/python/samples/samplebase.py", line 7, in from rgbmatrix import RGBMatrix, RGBMatrixOptions ImportError: cannot import name 'RGBMatrixOptions' from 'rgbmatrix' (/usr/local/lib/python3.7/dist-packages/rgbmatrix/init.py)**

Steps done as in readme instructions:

And here I cannot do nothing... Tried also a clean reinstall with downloading again with git, doing all the steps again. I tried also with python 2.7 usage, the same error. Reading other comments I realize that I am missing simple step... Thanks in advance Peter

Hi everyone I found my problem. Maybe solution will help others also fighting with this issue. On the file /urs/local/lib/python3.7/dist-packages/rgbmatrix/_init.py is missing one argument:

-- coding: utf-8 --

from future import absolute_import version = "0.0.1" author = "Christoph Friedrich christoph.friedrich@vonaffenfels.de" from .core import RGBMatrix, FrameCanvas

Because this file is write protected, first I had to change it to writable: sudo chmod 666 _init.py With nano adding the missing argument:

-- coding: utf-8 --

from future import absolute_import version = "0.0.1" author = "Christoph Friedrich christoph.friedrich@vonaffenfels.de" from .core import RGBMatrix, FrameCanvas, RGBMatrixOptions

Save it. Don't forget to change back permissions: sudo chmod 644 _init.py

Now all python scripts from samples folders are working. I don't know how disapeared this argument. Cheers Peter
