Cache does not seem to be caching. Slow autocomplete.

[ClayShoaf]

Issue

When I try to do a . autocomplete, it takes a long time to load the options. I have looked at some other issues, like #163, but I have not installed any other plugins. Please see the section called "ATTENTION" as it looks like there is probably a simple solution, but I am not sure exactly what I need to add/edit in my init.vim file.

If you are not using jedi-vim from Git (but e.g. from a distribution's package,
please try it with jedi-vim's Git master, too).

I assume that's what Vundle is doing when I include the line Plugin 'davidhalter/jedi-vim' in my init.vim file, but if not, please let me know and I will see if I can install it some other way.

jedi-vim.slow.webm

Steps to reproduce

You can use the following template (save it as minimal.vimrc in the directory
where jedi-vim is installed, cd into that directory, and run Vim with
vim -u minimal.vimrc):

set nocompatible

let script_dir = fnamemodify(expand('<sfile>'), ':h')
let &runtimepath .= ','.script_dir.','.script_dir.'/after'

" Put your config changes here.
" let g:jedi#show_call_signatures=1

syntax on
filetype plugin indent on

*** ATTENTION ***

I just tried that and it significantly increased the speed on the second autocomplete! It's not the 50 ms that someone else reported, but it does go much faster, which is good.

Any idea what I should add from this to my init.vim? This is all that's in mine right now:

set nocompatible              " be iMproved, required
filetype off                  " required

set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'davidhalter/jedi-vim'
call vundle#end()            " required
filetype plugin indent on    " required

set scrolloff=10

augroup AutoView
  autocmd!
  autocmd BufWinLeave * silent! mkview
  autocmd BufWinEnter * silent! loadview
augroup END

[davidhalter]

Thanks for the report, but this is unfortunately a known issue of davidhalter/jedi#1059

There is not a lot we can do here for now, because this is really an architectural issue. I'm trying to fix it by rewriting Jedi in Rust, but that's still years away from completion. My type checker is probably at 50-60% (mypy clone) finished, but even that will take a long time and after that I will start with completions.

The issue you are seeing here is that some large libraries like matplotlib and numpy are just too big for Jedi's current design. I'm closing, because this is really the Jedi issue that I've linked.

@davidhalter I appreciate the reply!
