AssertionError in _enrichment

[dschrein]

have you ever seen this? i also noticed that when i try to run aucell with the num_workers argument, it complains:

>>> auc_mtx = aucell(ex_matrix, regulons, num_workers=4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: aucell() got an unexpected keyword argument 'num_workers'

AssertionError:

here are all my imports

import os
import glob
import pickle
import pandas as pd
import numpy as np

from arboretum.utils import load_tf_names
from arboretum.algo import grnboost2

from pyscenic.rnkdb import FeatherRankingDatabase as RankingDatabase
from pyscenic.utils import modules_from_adjacencies
from pyscenic.prune import prune, prune2df, df2regulons
from pyscenic.aucell import aucell

and the cpu_count()

>>> import multiprocessing as mp
>>> mp.cpu_count()
4

Hi,

I just fixed the AssertionError in the latest release of pySCENIC 0.8.2 .
