test failures on CIT

I'm trying to get a PyFstat installation running on CIT, and getting test failures. (Though some basic examples to work already.)

1. something related to matplotlib backends again, MR incoming: [david.keitel@ldas-pcdev13 PyFstat]$ python tests.py Traceback (most recent call last): File "tests.py", line 5, in <module> import pyfstat File "/home/david.keitel/git/PyFstat/pyfstat/__init__.py", line 3, in <module> from .core import BaseSearchClass, ComputeFstat, SemiCoherentSearch, SemiCoherentGlitchSearch File "/home/david.keitel/git/PyFstat/pyfstat/core.py", line 15, in <module> import pyfstat.helper_functions as helper_functions File "/home/david.keitel/git/PyFstat/pyfstat/helper_functions.py", line 20, in <module> import matplotlib.pyplot as plt File "/home/david.keitel/.local/lib/python2.7/site-packages/matplotlib/pyplot.py", line 116, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/home/david.keitel/.local/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 60, in pylab_setup [backend_name], 0) File "/home/david.keitel/.local/lib/python2.7/site-packages/matplotlib/backends/backend_tkagg.py", line 6, in <module> from six.moves import tkinter as Tk File "/home/david.keitel/.local/lib/python2.7/site-packages/six.py", line 203, in load_module mod = mod._resolve() File "/home/david.keitel/.local/lib/python2.7/site-packages/six.py", line 115, in _resolve return _import_module(self.mod) File "/home/david.keitel/.local/lib/python2.7/site-packages/six.py", line 82, in _import_module __import__(name) ImportError: No module named Tkinter
2. After fixing that one, some Directory not empty or Device or resource busy errors in test 12. Full log attached. Might be a shutil version issue?test_ldas-pcdev13_20180111.log
