Don't have an answer to this unfortunately. Known issue: #489
Possible workaround: #326 (comment)
from pynvim.

A workaround is to use nest_asyncio. It is not a perfect solution as the behavior of nested asyncio loop can be quite unintuitive and strange, but works at least minimally:
[1]: import nest_asyncio
nest_asyncio.apply()
[2]: from pynvim import attach
nvim = attach('socket', path='/tmp/nvim.sock')
[3]: nvim.current.buffer[:] = 'foo'
from pynvim.

GH doesn't support uploading ipynb files, so here's the raw text of a minimal Jupyter notebook to reproduce the issue:
