luma.led_matrix not working on ZeroSeg 7-segment device after "Bullseye" install

[linuxminty]

Type of Raspberry Pi

Model 4B, 2GB

Linux Kernel version

Linux raspberrypi-4B 5.10.63-v7l+ #1488 SMP Thu Nov 18 16:15:28 GMT 2021 armv7l GNU/Linux

Expected behaviour

I use the ZeroSeg to display time and date with code from luma.led_matrix. It worked well with Buster operating system.

Actual behaviour

After installing "Bullseye" RPi operating system and attempting to run the luma.led_matrix code, I get the following error:

Traceback (most recent call last):
  File "/home/pi/luma7datetime.py", line 15, in <module>
    from luma.led_matrix.device import max7219
ModuleNotFoundError: No module named 'luma'

I tried to reinstall from https://luma-led-matrix.readthedocs.io/en/latest/install.html, but get the same error message. Help getting this fixed would be greatly appreciated.
