Can you try it after M-x load-library python RET and then evaluate
this new definition of python-shell-completion-native-try:

(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 "_")))

I'm not sure what "pyrepl" is or to "use" it, but just looking at web
search results, it seems to be connected to pypy, which is in the list
of python-shell-completion-native-disabled-interpreters, could that be
related?
