Issue starting up

[Dad-Ju]

Hello,

I fiddled around a lot, but did not get it working.

I want to setup this on my Raspberry Pi 3B (Zero W 1.1 in bestcase) to control some strips, sadly I don't get it to start up right...

I applied the fix from #53 and tried from master directly but no luck there. Maybe someone can help me get started :)

sudo ledcontrol --led_count 17

Try adding 'Werkzeug==2.2.2' to the requirements list in setup.py.

one more issue, that was fixed by doing.. sudo apt-get install libopenblas-base

error was root@raspberrypi:~/led-control# ledcontrol Traceback (most recent call last): File "/root/led-control/.eggs/numpy-1.26.4-py3.9-linux-armv7l.egg/numpy/core/init.py", line 24, in from . import multiarray File "/root/led-control/.eggs/numpy-1.26.4-py3.9-linux-armv7l.egg/numpy/core/multiarray.py", line 10, in from . import overrides File "/root/led-control/.eggs/numpy-1.26.4-py3.9-linux-armv7l.egg/numpy/core/overrides.py", line 8, in from numpy.core._multiarray_umath import ( ImportError: libopenblas.so.0: cannot open shared object file: No such file or directory

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for many reasons, often due to issues with your setup or how NumPy was installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

• The Python version is: Python3.9 from "/usr/bin/python3"
• The NumPy version is: "1.26.4"

and make sure that they are the versions you expect. Please carefully study the documentation linked above for further help.

Original error was: libopenblas.so.0: cannot open shared object file: No such file or directory

The above exception was the direct cause of the following exception:
