It seem your configuration of anything-ipython is wrong, be sure to read
carefully the instructions in anything-ipython.el.
I can't reproduce your error.
Here is my config:

,----[ Config thierry anything-ipython ]
| (require 'anything-ipython)
| (add-hook 'python-mode-hook #'(lambda ()
|                                 (define-key py-mode-map (kbd "M-<tab>") 
'anything-ipython-complete)))
| (add-hook 'ipython-mode-hook #'(lambda ()
|                                   (define-key py-mode-map (kbd "M-<tab>") 
'anything-ipython-complete)))

| (add-hook 'ipython-shell-hook #'(lambda ()

To have completion in python buffer (i.e in your python file, not the
shell) you have to start first the ipython interpreter, and then load
all the modules you have in your python file.
Load modules one by one in ipython interpreter or use from your file
C-c M (see above).
Be sure also to setup python-mode (PYTHON-MODE, not the bad one that
come with emacs) correctly.
Let me know if you have more problems.
