Python error in quantile_norm of module pulp

[mrheinnecker]

when executing:

cem-run supervoxels --cluster slurm -c 64 -g 12

the follwouing error occurs:
Traceback (most recent call last):
File "/home/rheinnec/miniconda3/envs/cebra1/lib/python3.9/runpy.py", line 197, in _run_module_as_main

lp_solvers = pulp.list_solvers(onlyAvailable=True)
AttributeError: module 'pulp' has no attribute 'list_solvers'

according to: snakemake/snakemake#2607

the list_solvers was updated to listSolvers

so i changed the line 1607 of file:
"/home/rheinnec/miniconda3/envs/cebra1/lib/python3.9/site-packages/snakemake/init.py"

from:
lp_solvers = pulp.list_solvers(onlyAvailable=True)
into:
lp_solvers = pulp.listSolvers(onlyAvailable=True)

this seems to fix the problem
