How to reproduce the problem from neovim/Vim startup (Required!)

1.open a empty python 2.type im(import)

[Shougo]

neosnippet-snippets does not have import snippet. So this is feature.

If you input if, you can get ifmain snippet.

And your configuration is wrong.

It must be:

call deoplete#custom#option('sources', {
            \ 'python':['jedi','neosnippet'],
            \})
