Cannot import sccoda.util.comp_ana #39

Closed

Description

I installed scCODA (pip install sccoda) without any problem/warning and performed the basic analysis following the getting started tutorial, until the model setup and inference. Unfortunately I cannot import sccoda.util.comp_ana function into python. Following the tutorial:

from sccoda.util import cell_composition_data as dat
from sccoda.util import data_visualization as viz
from sccoda.util.comp_ana import comp_ana as mod

doesn't work for my python installation (conda, python 3.9), thus I used

import sccoda.util.cell_composition_data as dat
import sccoda.util.data_visualization as viz

successfully. When I try to import comp_ana using:

import sccoda.util.comp_ana as mod

The kernel crushes. If I import sccoda separately;

import sccoda

And look for the possible functions, but I only can see cell_composition_data and data_visualization, but not comp_ana

comp_ana.py is under the sccoda/util folder where it is supposed to be. I am not sure what exactly the problem is, but somehow comp_ana is 'invisible'.

I have a Macbook pro M1 with 8-core, my environment details are:
