can't invoke "destroy" command

This is an "error" that occurs at the very end of using PESSTOFASTSPEC and does not really affect the reduction, but is annoying. This happens with the latest versions of the pipeline (with python 3) and Ubuntu/Linux (not sure if Mac OS as well).

_tkinter.TclError: can't invoke "destroy" command: application has been destroyed

Anyway, the quick solution is to comment out line 90 in the file _pylab_helpers.py in your matplotlib directory of your environment (i.e. manager.destroy() --> #manager.destroy()).
