I found the root cause of the failures.  The test needs python3 to run
correctly.  The machines where I was seeing the failures were still on
distros using python 2.  Specifically, RHEL 7.8 uses python 2 by
default.  Installing python 3 and changing the soft link
/usr/bin/python to point to python3 fixes the issue.
