No module named luma.led.matrix.device

I’ll start by apologising, I’m new to python and raspberry pi. I have very limited programming experience from when I used to mess around with some things a few years ago but mostly forgotten.

I’m trying to program an array of 4 8x8 LED matrices to display crypto currency prices. Right now Im stuck on the basics

I’ve cloned the repository, and when I try to run $ python examples/matrix_demo.py i get hit with Traceback (most recent call last): File "examples/matrix_demo.py", line 10, in <module> from luma.led_matrix.device import max7219 ImportError: No module named luma.led_matrix.device

My pip version is 9.0.1 and python version 2.7

I’ve been trying to figure out why its happening but I really dont know Please help 😦

@boringtrousers - see comment https://github.com/rm-hull/luma.examples/issues/24#issuecomment-379677387 - maybe a force reinstall will work for you?

Obviously the package would be different:

sudo -H pip install --upgrade --force-reinstall --ignore-installed luma.led_matrix

Thank you, I saw your comment but I haven’t been able to try this for the past couple of weeks, as I have been away. Just tried force reinstalling and it fixed the problem. Thanks a lot
