For reference, I saw a related pyqt DeprecationWarning (python 3.8) in another project

  /home/denolf/virtualenvs/pybox_ACEdYq/lib/python3.8/site-packages/oasys/util/oasys_util.py:
183: DeprecationWarning: an integer is required (got type float).  Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python.
