Hi there I'm trying to run Windowmasker in Galaxy and receiving the following error: "computing the genome length pass 1 pass 2 optimizing the data structure Traceback (most recent call last): File "/tools/software/galaxy/galaxy1/database/jobs/006/6476/set_metadata_bUlLkt.py", line 1, in <module> from galaxy_ext.metadata.set_metadata import set_metadata; set_metadata() File "/tools/software/galaxy/galaxy1/lib/galaxy_ext/metadata/set_metadata.py", line 14, in <module> import logging File "/usr/lib/python2.7/logging/__init__.py", line 26, in <module> import sys, os, time, cStringIO, traceback, warnings, weakref, collections File "/usr/lib/python2.7/weakref.py", line 14, in <module> from _weakref import ( ImportError: cannot import name _remove_dead_weakref" The usual suggested fix for this is to remove the Galaxy virtual environment (.venv) and recreated it. I have done that but the error persists. Galaxy is running here on Ubuntu 16.04 with Python 2.7.12. Any advice? Thanks! Peter
