Python 3 support

[harryslapalot]

Since Python 2 is EOL since January 1st 2020 it would be nice if Octohue supported Python 3. I just migrated my Octoprint Instance to Python 3 and it seems OctoHue is the only plugin I am using that doesn't support it. If it is already compatible, Octoprint must be told that it is. See here for guidance:

Migrating to Python 3

I was able to fix this issue by running sudo apt-get install libatlas-base-dev and then reinstalling OctoHue. Before it always showed "Installed UNKNOWN" after installation and the plugin wasn't there after reboot.

^^ this doesnt seem to work anymore ^^ any thoughts?

I have installed libatlas-base-dev but it still shows unknown and doesnt seem to install it, i have fully rebooted the pi as well

I too have the same issue!

I did do the sudo apt-get install libatlas-base-dev

Hope there is a fix

@BigWebstas @Lefo16 , I'm doing a fresh octopi install right now and I'll be doing. from scratch install of octohue as a part of that.

If there is anything specific you think i need to know to reproduce the issue let me know, alternatively, this was using an new install for you?

On my clean install I did find a package that numpy expected to be there that was missing... in ~/.octoprint/logs/octoprint.log i found the following:

2023-12-04 21:19:16,172 - octoprint.plugin.core - ERROR - Error loading plugin octohue Traceback (most recent call last): File "/home/pi/oprint/lib/python3.9/site-packages/numpy/core/init.py", line 24, in from . import multiarray File "/home/pi/oprint/lib/python3.9/site-packages/numpy/core/multiarray.py", line 10, in from . import overrides File "/home/pi/oprint/lib/python3.9/site-packages/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

It was fixed with apt-get libopenblas-dev

I will take a closer look and see if I can get around the use of numpy, its being a little troublesome. But It wont be replaced quickly

this solution works. thank you!

[entrippy]

Great to hear. I've looked in to removing numpy, and its not straight forward, there is a bit of a dependency chain as the module used for colour conversion relies on it.

For now I'll document that libopenblas-dev needs to be installed in the readme and will continue to research workarounds.

[entrippy]

oh... might have figured out how to drop numpy and colourmath all in one go.

Needs some testing though

Has been resolved in the coming 0.7.0. this release might take some time due to a large number of other optimisations.
