examples not working 'weather' and 'LCD' (v 1.0.0)

[bsimmo]

So installed the new version v1.0.0
BME and averaging etc work fine.

weather.py and LCD.py do not.

Could it be NUMPY 2.0.0 ? Which I just got fixed on pywheels so we can install. #32
See my install log here

#33 (comment)

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: Python3.11 from "/home/weatherhat/.virtualenvs/pimoroni/bin/python"
  * The NumPy version is: "2.0.0"

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:

Followed the link in the error and read to this
https://numpy.org/devdocs/user/troubleshooting-importerror.html#raspberry-pi

Tried sudo apt install libatlas-base-dev
but that didn't help

Ran out of time for now.

Same issue here in RPI Zero W. Fixed this by installing two missing dependencies:

sudo apt-get install libopenblas-dev
sudo apt-get install libopenjp2-7

You can also see in the error message that it complains about not finding the binaries (.so) for those libraries.
Note that those are different from libopenatlas which was already in the instructions.

I've also downgraded numpy to 1.26.4 (pip install -U numpy==1.26.4), but don't know if that was a required step to make it work.
