Jedi-vim: Problem with autocompletion: =jedi#complete_opened(0) -- Omni completion (^O^N^P) Pattern not found

[zotroneneis]

Issue

The completion works fine for python standard library modules.
But when I, for instance, try:

import numpy as np
np. (then pressing CTRL + Space)

I get the following error message:

=jedi#complete_opened(0) -- Omni completion (^O^N^P) Pattern not found

What's the output of

:python3 import numpy; print(numpy)

?

[blueyed]

FWIW: the example should be numpy. and not np. in the 2nd line?!
I am seeing -- Omni completion (^O^N^P) Pattern not found with np. - and not the =jedi#complete_opened(0) before it.

[zotroneneis]

@blueyed :
Yes, you're right. Fixed it.

@davidhalter
The output is:

Traceback (most recent call last):
File "", line 1, in
ImportError: No module named 'numpy'

[blueyed]

@zotroneneis
Then you do not have numpy installed with the Python you are using in Vim.
You will have to e.g. activate your virtualenv before, use something like pyenv or Neovim for better Python support in general.

btw: it is still unexpected for the =jedi#complete_opened(0) to show up..
Can you try the following patch, if it improves this (i.e. makes it more silent)?

[zotroneneis]

@blueyed:
The patch did not change the behavior.

Numpy should actually be installed with the python I am using, as conda info --envs yields

root                  *  /home/myname/anaconda3

and conda list | grep numpy returns

numpy                     1.11.3                   py35_0  
numpydoc                  0.6.0                     <pip>
numpydoc                  0.6.0                    py35_0 

Also I can run the following code:

import numpy as np
print('I like jedi')

with :w !python and :w !python3without any error.

Do I really need pyenv or Neovim to make it run, when I just want to use the root anaconda python version?

[blueyed]

It looks like your Vim installation is not using the same python3 as used in the $PATH?!

Try :!python3 -c "import sys; import numpy; print(sys.modules['numpy'])".
And :!which python3.

Your Vim / jedi-vim Python seems to be /usr/lib/python3.5/, but maybe/probably conda is somewhere else?!

Do I really need pyenv or Neovim to make it run, when I just want to use the root anaconda python version?

No, but I have no experience with setting up conda for Vim, but now that Neovim makes it more flexible.

[zotroneneis]

@blueyed
Thanks for your help. I ended up installing neovim and now everything works out fine out of the box!

[barra51]

@blueyed
Nice explanation mate. Thanks for sharing this solution, I had the same problem.

[davidhalter]

Virtualenv support should now also be much better in VIM.
