Error when install Python Packages for UMEP about umep-processing HOT 8 CLOSED

Evelina, write the following code in your QGIS Python console and report the result. @j3r3m1 , do you have any ideas on how to solve this? I know Evelina have another Python installation (3.11) on her computer also.

import numpy
numpy.__version__

import numba
numba.__version__

from umep-processing.

Numpy version:
1.24.1

Numba version:

Does some of the versions of numpy not support numba?

from umep-processing.

It seems this problem has been met in two other issues previously:
#543 and #30

It has been resolved using a Numpy version lower than 1.24.

Maybe we should specify the numpy library to be used ?

from umep-processing.

I changed the numpy version to 1.23.3 and it works now! I think it is good to specify the type of numba library used.

from umep-processing.

What is the numba version you are using ? Can you check using pip list and checking the version associated to numba ?

Here are the numba versions and the corresponding numpy dependency: https://numba.readthedocs.io/en/stable/user/installing.html#version-support-information

I do not really know why the numba version installed is not directly the right one (associated to the numpy dependency). Is it the first time you install UMEP ? If yes it might be that we do not check that the numba version installed works for the installed numpy version.
Should we add a way to check that

from umep-processing.

I am using numba version 0.56.4. And no it is not the first time using UMEP.

from umep-processing.

Do you remember when was the last time you updated the UMEP-processing plugin ? I suppose the problem comes from the fact that your numpy version was updated (outside UMEP update) but that the last update you made of UMEP created the version conflict...

from umep-processing.

As this seems solved, I will close this.
