@Shougo Unfortunately the problem persists after I updated it to the latest.

OK. I get it.

But please provide the real minimal vimrc.

It is the real minimal vimrc.

set rtp+=~/work/deoplete.nvim/
set rtp+=~/src/deoplete-jedi

let g:deoplete#enable_at_startup = 1
let g:deoplete#sources#jedi#show_docstring = 1

call deoplete#custom#option('auto_complete_popup', 'manual')
call deoplete#custom#option('min_pattern_length', 0)

This is jedi's issue.
Please create the new issue in jedi issues.
https://github.com/davidhalter/jedi/issues

And I have found the reason.
The patch fixes the problem for me.
