Elpy: What to do to get eldoc documentation via company?
In the examples on the Internet, there is a documentation appears next to the autocomplete menu, if it is possible. I have not this by default

That example uses a pretty old version of Elpy, which still used the auto-complete library. Due to various problems with auto-complete, Elpy moved to company-mode, which does not by default have these docstring popups. There are two options for you.
First, you can live without the popups. C-h on an option will display the full docstring in another buffer, so you only lose the automatic popup, which can even get annoying at times.
Second, you can install the company-quickhelp package, which replicates the pop-up behavior of auto-complete for company-mode. This is another external package, but it should do what you want.
Let me know if this solves your question, or if there are any further problems :-)

Error output when I use F1 or C-d
Output from Backend
There was some unexpected output from the Elpy backend. This is
usually some module that does not use correct logging, but might
indicate a configuration problem.
Output
** (__main__.py:9285): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-zFz4kAJHDm:
Hello!
I hope the company-quickhelp module works as you expected?
The output you see there is from some module you are using which Elpy does not control. Ideally, modules should not simply write to stdout but use the logging module, but well, not all modules are well-behaved like that.
Sadly, Elpy can not distinguish if output from the subprocess is simply a status message or if it is an indicate of an error, so it shows the output to you. If it's expected output like this, you can simply bury the buffer and ignore it.
Does this help?

Activate company-quickhelp-mode and now all works fine.
(defun prelude-personal-python-mode-defaults ()
"Personal defaults for Python programming."
;; Enable elpy mode
(elpy-mode)
;; Jedi backend
;; (jedi:setup)
;; (setq jedi:complete-on-dot t) ;optional
;; (auto-complete-mode)
;; (jedi:ac-setup)
(setq elpy-rpc-python-command "python3")
;; (python-shell-interpreter "ipython3")
(company-quickhelp-mode)
)
(setq prelude-personal-python-mode-hook 'prelude-personal-python-mode-defaults)
(add-hook 'python-mode-hook (lambda ()
(run-hooks 'prelude-personal-python-mode-hook)))
Thank you for your help and suggestive answers.
