does jedi support python 3 ?

I am using python 3.4.3 in virtualenv. While opening a python file I get these errors.

"asynctest.py" [noeol] 24L, 454C
Error detected while processing function provider#python#Call:
line    1:
Exception('no request handler registered for "python_execute_file"',)
Press ENTER or type command to continue

If I disable the jedi plugin these errors go away. Also in python 2 these errors dont pop up. Any idea what can be done to fix it ?

let g:jedi#force_py_version=3 or call jedi#force_py_version(3)

@vmindru Thanks for sharing. It will slowdown your Vim startup though. I recommend to use Neovim instead in general, and in this particular case you are able to configure the plugins usually instead (jedi-vim (g:jedi#force_py_version), UltiSnips etc).

If you want to keep this method, see how jedi-vim does it: https://github.com/davidhalter/jedi-vim/blob/7ddc50829eaa8350aa2bd60f4bb04e6620329b4f/autoload/jedi.vim#L76-L78:

        " Get default python version from interpreter in $PATH.
        let s:def_py = system('python -c '.shellescape('import sys; sys.stdout.write(str(sys.version_info[0]))'))
        if v:shell_error != 0 || !len(s:def_py)
            if !exists('g:jedi#squelch_py_warning')
                echohl WarningMsg
                echom 'Warning: jedi-vim failed to get Python version from sys.version_info: ' . s:def_py
                echom 'Falling back to version 2.'
                echohl None
            endif
            let s:def_py = 2
        elseif &verbose
            echom 'jedi-vim: auto-detected Python: '.s:def_py
        endif

And you should also set g:jedi#force_py_version then. Related: https://github.com/davidhalter/jedi-vim/pull/674.
