Solved: It was jedi version missmatch: jedi-0.18.1 after downgrade to: pip install jedi==0.17.2 everything woks.

it also required pip install virtualenv

my .emacs:

(require 'jedi-core)
(require 'company-jedi)

(with-eval-after-load 'jedi-core
  ;;standard-jedi-settings
  ;; (setq jedi:environment-virtualenv (list (expand-file-name "~/.emacs.d/.python-environments/")))
  (setq jedi:environment-root "jedi")
  (setq jedi:server-command (jedi:-env-server-command))

  (add-hook 'python-mode-hook 'jedi:setup)
  (setq jedi:complete-on-dot t)
  (setq jedi:use-shortcuts t)
)

(with-eval-after-load 'company-jedi
  (defun my/python-mode-hook ()
    (add-to-list 'company-backends 'company-jedi)
  )
  (add-hook 'python-mode-hook 'my/python-mode-hook)
  (add-hook 'python-mode-hook 'company-mode)
)

It would be "nice" if this 'little detail' was somewhere in the documentation
