Hmm, that looks like it should be working.  Wait, when you said

    I was already using that (wrapped in a "with-eval-after-load
    'python") from:

    https://github.com/jorgenschaefer/elpy/issues/887#issuecomment-275175119

    to no avail.

You meant the code from that exact comment?  That's a broken solution,
try this instead:

    (with-eval-after-load 'python
      (defun python-shell-completion-native-try ()
        "Return non-nil if can trigger native completion."
        (let ((python-shell-completion-native-enable t)
              (python-shell-completion-native-output-timeout
               python-shell-completion-native-try-output-timeout))
          (python-shell-completion-native-get-completions
           (get-buffer-process (current-buffer))
           nil "_"))))

If it's still not working, please post the contents of buffer " *Python
completions redirect*" (note the leading space).
