methratio.py AssertionError

[animaltracks7]

Hi, I'm getting an error when running methratio.py. Code: methratio.py -o methratio.txt -d Genome.fna -r bsmap.bam Output: [methratio] @Sat Apr 9 20:12:26 2022 Using 90% of available memory (11165 MB) as limit [methratio] @Sat Apr 9 20:12:26 2022 Presorting inputs [methratio] @Sat Apr 9 20:12:26 2022 Processing 8 chromosomes at a time Traceback (most recent call last): File "/usr/local/bin/methratio.py", line 590, in main() File "/usr/local/bin/methratio.py", line 136, in main chromPool = ChromPool(maxChromProcs) File "/usr/lib/python3.8/multiprocessing/pool.py", line 212, in init self._repopulate_pool() File "/usr/lib/python3.8/multiprocessing/pool.py", line 303, in _repopulate_pool return self._repopulate_pool_static(self._ctx, self.Process, File "/usr/lib/python3.8/multiprocessing/pool.py", line 319, in _repopulate_pool_static w = Process(ctx, target=worker, File "/usr/lib/python3.8/multiprocessing/process.py", line 82, in init assert group is None, 'group argument must be None for now' AssertionError: group argument must be None for now

Any idea what is wrong? Thanks.

Hi, I just ran into the same issue running make test on an Ubuntu 18.04 system. Were you able to resolve this? Thanks.
