Python 绝地维姆：弹出窗口仅在某些情况下出现

我在MacYosemite上安装了几个插件，用Vim7.3创建了一种python IDE

有关插件-设置的列表，请参见my.vimrc：

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
filetype plugin indent on
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required
Plugin 'gmarik/Vundle.vim'
Plugin 'klen/python-mode'
Bundle 'altercation/vim-colors-solarized'
Bundle 'scrooloose/nerdtree'

Bundle 'davidhalter/jedi-vim'

" All of your Plugins must be added before the following line
call vundle#end()            " required

let g:pymode_options_max_line_length = 79
let g:pymode_options_colorcolumn = 1
let g:pymode_python = 'python'
let g:pymode_indent = 1
" Don't autofold code
let g:pymode_folding = 0


" NerdTree
map <F2> :NERDTreeToggle<CR>

" Powerline setup
set guifont=DejaVu\ Sans\ Mono\ for\ Powerline\ 9
set laststatus=2

如果我在python文件中工作，我希望每次按Ctrl空格或句点时都会出现一个自动完成的弹出窗口，但事实并非如此

范例 无弹出窗口：

这里有一个弹出窗口

有什么想法吗？

不清楚你做了什么，使用了什么扩展，你到底在问什么。你必须提供更多的信息，比如你已经做了什么，你到底想发生什么，错误是什么。对此感到抱歉-我添加了一些信息。
