Can't import RVector3 when installing package

[gabrahamastro]

Problem

Having created the conda environment pg on Spyder as instructed by the installation instructions, when in the pg environment and trying to run the code
import pygimli as pg
an error comes up which reads
cannot import name 'RVector3' from 'pygimli.core.core'

Background

Operating system: MacOS 15.0 (x86_64)
Python version: 3.11.9
pyGIMLi version: 1.5.1
Sypder version: 6.0.1
Way of installation: Using conda

Steps to reproduce

I entered the pg conda environment by changing the default environment in the Consoles tab, before entering the below after having entered IPython automatically.

import pygimli as @@#pg

Expected behavior

This should import the package, with no error responses.

Actual behaviour

The package was not imported correctly, with the following output being generated:

[halbmy]

This is related to an incompatible suitesparse version. Please have a look at #761 and the solution given there.

[gabrahamastro]

When running the below in terminal as per #761 before retrying in Spyder, it worked perfectly - thank you @halbmy!
conda create -n pg -c gimli -c conda-forge "pygimli>=1.5.0" python=3.10 suitesparse=5
