Enable filetype recognition with jupytext converted ipynb files

[naefl]

Hi,

I'm using https://github.com/goerz/jupytext.vim to convert jupyter notebooks to vim-readable files.

I've set the filetype to be python, i.e. when I open a .ipynb file, set ft? shows me filetype=python, however I don't see any syntax highlighting.

I can also not force it with :Semshi enable

Here's relevant parts from my .vimrc:

Plug 'numirias/semshi', {'do': ':UpdateRemotePlugins'}

let g:semshi#filetypes = ['python']

Any ideas?

Much appreciated!
