feems cannot be imported properly

[Galinqiang]

Hi @haywse @jhmarcus ，
I wanted to use feems for analysis, but I ran into some problems with it
# feems
from feems.utils import prepare_graph_inputs
from feems import SpatialGraph, Viz
from feems.cross_validation import run_cv
When I used the above statement to import the feems package for analysis, I encountered the following problems：
from feems.utils import prepare_graph_inputs
File "/home/apps/anaconda3/envs/app/lib/python3.9/site-packages/feems/init.py", line 3, in
from .cross_validation import run_cv
File "/home/apps/anaconda3/envs/app/lib/python3.9/site-packages/feems/cross_validation.py", line 8, in
from .spatial_graph import query_node_attributes
File "/home/apps/anaconda3/envs/app/lib/python3.9/site-packages/feems/spatial_graph.py", line 8, in
import sksparse.cholmod as cholmod
ModuleNotFoundError: No module named 'sksparse'
I tried to download the sksparse package, there is no Linux version.
How do I fix it? Is it my code or my installation or my version issue？

Thanks in advances,
Gao

Hi @Galinqiang, you need functions from the scikit-sparse (sksparse) package to run FEEMS code. You could install this package using instructions from here: https://github.com/EmJay276/scikit-sparse (there seems to be some caveats for Windows installation, but Linux should be fine)

I would recommend creating a conda environment, then conda install -c condo-forge scikit-sparse should work.
