Python binding: AttributeError: 'rgbmatrix.core.RGBMatrixOptions' object has no attribute 'panel_type'

[robgyiv]

First of all, thanks so much for creating such a great library! It's been a lot of fun to be able to start writing some code and have it show on a panel so easily.

Currently on master, after following the readme and building for Python I get the following error:

$ sudo ./samples/pulsing-colors.py
Traceback (most recent call last):
  File "./samples/pulsing-colors.py", line 41, in <module>
    if (not pulsing_colors.process()):
  File "/home/pi/code/github.com/rpi-rgb-led-matrix/bindings/python/samples/samplebase.py
", line 56, in process
    options.panel_type = self.args.led_panel_type
AttributeError: 'rgbmatrix.core.RGBMatrixOptions' object has no attribute 'panel_type'

I have set HARDWARE_DESC=adafruit-hat in lib/Makefile.

If I checkout to commit 4c9a4036f44f and rebuild this does not happen. There may be a more recent commit that also works but I haven't tried it.

I'd be happy to contribute to the issue (more so in Python than C++) but may need some direction first.

Thanks again and let me know if any more information would be useful.

Hardware:

• Raspberry Pi 2 (Raspbian GNU/Linux 10 (buster))
• Adafruit RGB Matrix Bonnet
• LED panel

I am also experiencing this! master appears to be broken

It looks like commit 56b87b98f8aea9a95ee93449cf00831bcb3f0efa broke the python bindings.

I found the problem.

The script recommended by adafruit installed an old version into /usr/local/lib/python(2|3)/dist-packages which was being picked up before the local (not installed) version.

Thanks @cpforbes - this was the case for me as well as I used the adafruit guide initially. So the fix was:

• Removing rgbmatrix from /usr/local/lib/python(2|3)/dist-packages
• Rebuilding from the Python bindings in this repo
